1 Introduction

The real estate industry encompasses a wide range of activities beyond the traditional concept of buying or selling properties. It encompasses the design, financing, development, construction, and management of land, infrastructure, and buildings [ 67 ]. The dynamics of real estate development are rapidly evolving, with a growing link between construction, marketing, regulation, finance, and management [ 84 ]. Digital real estate refers to any domain name, website, or blog that can be found online, and it encompasses buying or selling properties such as houses, apartments, or plots of land [ 79 ]. According to recent estimates, global residential and commercial real estate is valued at USD 162 trillion and USD 29 trillion, respectively [ 120 ]. In 2017, global commercial real estate transactions reached USD 873 billion, increasing to USD 30,000 billion by 2019. The value of global residential properties also grew, reaching USD 160,000 billion in 2020 [ 114 ]. Additionally, international commercial real estate reached USD 32.6 trillion, and residential real estate value grew by 13%, totaling USD 258.5 trillion [ 112 ]. These figures demonstrate that commercial and residential property transactions have grown more than any other type of real estate asset worldwide.

The real estate sector plays a significant role in the economies of nations worldwide. In the United States, the sector contributed 11.13% to the gross output, while in China, it represented 5.98% of GDP [ 134 ]. In Australia, the real estate market accounted for 11.4% of the GDP of its capital cities [ 19 ]. In Malaysia, the real estate industry contributed 4.2% to GDP from 2011 to 2014 [ 94 ]. In India, the real estate sector has a significant impact, accounting for approximately 7% of GDP and providing a significant number of job opportunities [ 117 ]. These figures demonstrate that the real estate sector is a significant contributor to the wealth of nations worldwide and plays a significant role in the GDP of many countries.

The global real estate industry is undergoing a significant transformation in response to the integration of digital technologies. It is estimated that approximately one-third of countries have already digitized their land records [ 95 ]. The fourth industrial revolution, characterized by the emergence and development of technologies such as big data analytics, cloud computing, machine learning, the Internet of Things (IoT), Artificial Intelligence (AI), distributed manufacturing, 3D printing, robotics, and automated decision-making, has brought about significant disruption in various industries and has influenced the evolution of the real estate industry as well [ 100 , 114 ]. These technologies have created new opportunities for investment and growth, as well as new risks and challenges. The digitalization of the real estate industry is expected to continue to shape the future of the sector in various ways.

Digital technologies and decision-making systems have become integral to the digital transformation of the real estate industry, promoting innovative methods for acquiring, operating, and managing properties [ 98 ]. The growing accessibility of digital real estate tools has benefited customers, developers, planners, economists, and institutions alike. All stakeholders, including buyers, sellers, financial institutions, and brokers, require access to real estate data to make informed decisions. Therefore, examining and reviewing current research on digital real estate technologies and tools is necessary. This study conducts a bibliometric and systematic review of published scientific literature on digital real estate, focusing on digital real estate technologies and their applications. The study recommends future research directions for mainstreaming digital technologies and real estate development and management tools. The research specifically tries to address the following research questions:

RQ1: What are the common themes or thematic areas in digital real estate?

RQ2: How integrating different technologies can help in transforming digital real estate?

2 Methodology

The research design employed in this study is based on a longitudinal and systematic literature review, utilizing bibliometrics, historical trend analysis, and thematic analysis. Through this analysis, the study aims to identify specific digital real estate studies, technologies, and tools that have been developed and implemented in the industry.

2.1 Data collection

The Web of Science database was utilized for retrieving relevant publications for the study. A search query of "Digital Real Estate" was used to obtain a total of 616 results from the database on 8th August 2021. After carefully examining the titles and themes of these publications, 229 were deemed irrelevant to the applied query and were subsequently excluded. The methodology employed in this study is summarized in Fig.  1 , which illustrates the flowchart of the research process.

Research methodology

A systematic review is a technique used to evaluate or summarize the results of multiple studies. It is achieved by identifying, selecting, evaluating, and synthesizing available and appropriate research evidence (Gates & March, 2016). It can also be referred to as a meta-analysis. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were adopted in this study to analyze literature based on a checklist of 27 items, along with a flow diagram of four phases, providing a robust and detailed framework for the systematic review. The purpose of using PRISMA guidelines is to provide transparent and comprehensive systematic or meta-analysis of research areas within the research community [ 59 , 70 , 72 , 99 , 101 ]. On the Web of Science platform, a total of 387 publications were obtained after applying filters to include only those suitable for review. Among these, 150 were articles that underwent a screening process, and those publications that failed to meet the inclusion criteria based on abstract examination were excluded, resulting in a final set of 32 publications for this thematic analysis. The number of articles extracted from the Web of Science database using the PRISMA flow diagram is illustrated in Fig.  2 . The inclusion criteria for this study were any publications in the selected database that analyzed and examined the topic of digital real estate in a comprehensive manner. After reviewing the abstracts, publications that did not meet the inclusion criteria were removed. Articles focused on mathematical modeling, the real estate brokerage industry, 3D modeling, digital financial services, pricing models, building construction, urban expansion, and environmental protection were excluded. Microsoft Excel 365, Microsoft PowerPoint (for listing and infographics), Mendeley Desktop (for citation), and VosViewer 1.6.16 (for keyword analysis) were used in this study.

2.2 Data analytical tools

2.2.1 bibliometric analysis.

Bibliometrics is a method used to analyze and quantify the growth of published literature on a specific topic [ 25 ]. It supports historical assumptions about field development, recognizes links between scientific advancement and policy changes, and explores the formation of interdisciplinary fields [ 131 ]. The process of bibliometrics consists of two steps: collecting related work from the appropriate database through a valid search query and reviewing and analyzing the searched work [ 48 ].

For this study, a topic search was conducted using selected keywords that included searches from the title, abstract, and author's keywords. Bibliometric analysis covers all types of publications, such as academic articles, books, conference papers, etc. The search incorporated Title, Abstract, and Author's keywords to identify relevant publications. The year limit was not applied to the search criteria, so according to the keywords, the oldest article was from 2006. Therefore, it can be assumed that publications were extracted from the duration of 2006–2021.

The retrieved data of published literature was exported to Microsoft Excel and incorporated a year-wise number of publications, countries, authors, journals, citations, and keyword analysis. All cited references and full records were exported in text file format (delimited tabs) and used for network visualization in VOSviewer (version 1.6.16). The exported data comprises title Information, source title (journal name), author-wise publication data, publication year, subject categories (discipline), abstract, author’s keywords, language, and the number of citations (if present on publication). VOSviewer (version 1.6.16) is an open software used to analyze bibliometric data through a visualization network based on co-authorship and co-citation (van Eck and Waltman, 2009). The research findings were reaffirmed by using the online tools “Citation Report” and “Analyse Results” of Web of Science.

2.2.2 Thematic analysis

Thematic analysis is a qualitative or descriptive study approach that is widely used for the analysis of qualitative data in various studies (Attride-Stirling, 2001a, Braun & Clarke, 2008, Nowell et al., 2017a, Naeem & Rana, 2020, Zilembo, 2021). It is a methodological procedure of coding that examines and describes common facts by creating themes. A four-phased theme development approach was used in this study to identify, select, and name thematic areas: Initialization, Construction, Rectification, and Finalization, to ensure high-quality results and findings (Mojtaba Vaismoradi, 2016).

The first step in the thematic analysis process included familiarization with all published articles and generating provisional ideas [ 35 ]. At the initial stage, coding was done for generic themes extracted from published articles using an inductive approach (also known as open coding with no pre-determined codes). The process was repeated three times to revisit articles to identify any missed code/theme. After that, themes were constructed based on a qualitative analysis of the content of published articles. The constructed themes were reviewed again as a final refinement until different themes were merged as sub-themes under the umbrella of major themes. All the sub-themes were also discussed under each finalized theme.

3 Results and discussions

3.1 bibliometric analysis.

The bibliometric analysis conducted in this study provides an overall review of publications, including historical development of literature, publication sources analysis, citation analysis, country analysis, and keyword analysis. The summary of the bibliometric analysis is presented in Fig.  3 . This analysis provides valuable insights into the current state of research on digital real estate and highlights key trends and areas for future research and development.

Summary of bibliometric analysis

The overall summary of the publications is presented in Fig.  3 . A total of 1,283 authors have published research on digital "real estate." The most citations were observed in 2020 and 2021, with an average citation of 6.0 per article.

The trend of a particular topic can be analyzed through the annual number of publications. Results showed an annual increase in the number of publications on digital real estate until 2020 (Fig.  4 ). The first publication on digital real estate was in 2006, with 14 publications published. Results show that in 2006, 08 publications were published, which increased to 76 publications in 2020 and 43 by August 2021 (Fig.  4 a). This identifies an expansion of research interest of the scientific community in digital real estate. There are nine most productive journals in which most articles have been published on digital real estate. Automation in Construction, Remote Sensing, Computers Environment and Urban Systems, Geocarto International, Building Research and Information, International Journal of remote Sensing, Annals of The Association of American Geographers, Sensors, and Science of the Total Environment are the most productive journals (Fig.  4 b). Citation analysis revealed which publications on digital real estate were the most-cited ones (Table 1 ). The documents on digital real estate received 2,331 citations (an average of 6.0 citations per document). The total number of citations increased from 2007 to 2020 and up until August 2021.

3.2 Keyword analysis

Keyword analysis shows the precise content of digital real estate research. There were 2061 distinct keywords and 40 unique keywords. VOSviewer, an open-source software, was used to visualize the linkages and co-occurrence of specified or selected keywords by study authors. The circles in the visualization map represent the co-occurrence of each keyword, and the diameter of a circle shows the number of links between one keyword and another. Therefore, the larger the diameter of a circle, the more linkages with other keywords. The line thickness between two circles indicates how often keywords appear together. Figure  6 shows keywords used in publications on digital real estate with at least five times the co-occurrence of a keyword in extracted publications. This analysis has demonstrated that the concepts of GIS, blockchain, and BIM were the most frequently used keywords in digital real estate research.

Geographic Information System (GIS) is a valuable tool for enhancing access to documents and data, expediting transactions [ 38 ]. Its capabilities include creating three-dimensional maps and models, assessing the livability of an area, and presenting diverse datasets that assist real estate development [ 8 , 76 ]. On the other hand, Building Information Modeling (BIM) functions as a digital representation of a building's physical and functional attributes [ 22 , 128 ]. Through BIM, available data and information in digital format can be easily edited, copied, and shared with project stakeholders. This approach saves time and costs, enhances design and communication processes, boosts productivity and efficiency, and reduces the likelihood of errors [ 88 , 104 ]. Additionally, blockchain technology has been investigated to digitize and legitimize informal land ownership across various regions worldwide. Blockchain can significantly save time and money by eliminating paperwork, reducing fraud, and expediting transactions. Its implementation has the potential to revolutionize the field of land administration and contribute to streamlined and transparent processes [ 85 ]. This highlights the role of these technologies and concepts in shaping the future of the digital real estate industry.

3.3 Themes of digital real estate

Thematic analysis has proven to be a valuable approach to identifying recurring themes within the realm of digital real estate. As a qualitative data analysis method, it involves discerning and constructing themes from a given dataset. This analytical technique enables the segmentation and categorization of extensive data in an easily comprehensible manner [ 5 , 69 ]. It serves as a means to identify, analyze, and interpret patterns of meaning, commonly referred to as "themes," or shared characteristics inherent in qualitative data [ 16 , 81 ]. After thoroughly reviewing selected articles, themes were categorized and named as Information and Communication Technology (ICT), Data Collection Technologies, Data Networking Tools, and Decision-Making Systems (Fig.  7 ).

Nowadays, ICT plays a vital role in every domain of life in this era of technology. ICT is used in smart cities to enable real-time monitoring, proficient management of urban facilities, and public safety insurance. ICT can promote the modernization process, and it positively affects urbanization and regional development. Data collection technologies deal with hardware and gadgets. In real estate, gadgets are used to tell a digital story based on augmented information through the integration of VR and BIM, real-time tracking of accidents, and as-built modeling with Lidar and 3D laser scanning. Various data collection methods and devices have been developed with the passage of time to augment real estate activities. Data Networking Tools means to use digital telecommunications that allow devices to share resources on a network. It has been used in several real estate domains, including coordinating multi-site construction projects via federated clouds, indoor door environment detection, reconstruction and modeling of as-built 3D pipelines, etc. Decision-making is a critical part of a typical real estate property valuation, as selecting a home to purchase or rent is an important multi-criteria decision. From a monetary point of view, a property purchase can be the largest investment an individual can make and carries a high financial risk. The decision is primarily based on three high-level criteria: household needs, building facilities, and location characteristics. Decision-making systems or procedures fed with property information are based on different methods and models. Some of them are geographic information systems (GIS) for locational characteristics/geostatistical analysis/geographic locations and building information systems for describing building details/facilities. While the more dominant approach involves artificial-intelligence-based methods in the framework of Geo-Computation.

The convergence and integration of various data sources and technologies (such as GIS, BIM, AI, and networking) in the real estate domain have the potential to enhance decision-making, improve efficiency, and provide valuable insights for investors, developers, and stakeholders. This digital transformation will likely continue shaping the future of real estate and urban development. All these themes represent the key areas where digital technologies are being applied to transform the real estate industry.

3.4 Information and communication technology

3.4.1 urbanization and smart city.

Urbanization is a process that is driven by technological advancements, particularly in the field of information and communication technology (ICT). ICT significantly promotes modernization and positively impacts urbanization and regional development [ 121 ]. It also contributes to reducing poverty by generating employment opportunities and enhancing per-capita income (T.D. Stanley, Chris Doucouliagos, 2015). The widespread use of ICT in urban planning and management, including infrastructure, property and land records, finance and mortgage, and digital information systems [ 31 , 109 ], has led to the emergence of the concept of the "smart city."

The review showed that the smart city concept has been extensively covered in the digital real estate literature (Fig.  8 ). Smart buildings are shifting real estate from the physical to the digital realm. Technology has become the main differentiating factor for real estate in smart cities, both at the city and property scales [ 54 ]. Real estate technology in smart cities is considered an evolving solution to address the challenges of urbanization and achieve sustainable development [ 10 ]. Smart buildings, smart mobility, smart citizens, smart governance, smart education, smart infrastructure, smart technology, and smart energy are all components of a smart city, and they are interconnected through the Internet of Things and Big Data. The real estate sector plays a crucial role in the transition towards smart cities and is making rapid progress in the development and innovation of smart buildings in smart cities [ 47 ].

Sub-Themes of Information Communication Technology (ICT)

A smart city utilizes comprehensive ICT infrastructure to enable real-time monitoring, efficient management of urban facilities, and public safety. The smart housing concept and commercial real estate are two areas that are closely linked to smart cities [ 111 ]. Real estate is shifting from a physical to a digital environment through smart cities, and commercial real estate is shifting from providing assets to providing services [ 54 ]. Policymakers around the world are actively supporting and implementing smart city concepts. The Covid-19 pandemic has further accelerated the trend towards smart built environments, which are equipped with smart devices, such as sensors, and can interact intelligently with their human occupants and assist them in their daily activities [ 127 ]. While ICT acts as a primary engine of urbanization, it also has the potential to widen the digital divide, which can impede urbanization. In the information age, the digital divide poses a significant challenge to healthy urbanization. However, if the digital divide can be reduced, there is huge potential for effective urban governance. The government plays a crucial role in urbanization and technological progress, and government-led and ICT-based urbanization is believed to mitigate the effects of the digital divide and achieve balanced regional growth [ 121 ] .

3.4.2 Digitalization

Digitalization refers to the process of converting information into digital format and making everything that can be digitized (Bhadra, 2015). It involves using digital technologies to transform business models and create new revenue streams and value-producing opportunities, leading to a digital business [ 15 , 37 ]. It is closely linked to future socioeconomic pathways such as urbanization, sustainability, climate change, and demographics, which all significantly impact the daily lives of individuals and society [ 29 ].

In the real estate industry, digitalization is important for coding residential property attributes, such as location, size, and standard, in digital format [ 111 ]. This has led to real estate organizations investing in digitalization and modern computer-aided facility management software [ 49 ]. This provides the input for supporting Building information models (BIM), big data, Internet of Things (IoT), augmented reality (AR), blockchain, and building information standards [ 49 ]. The COVID-19 pandemic has provided an opportunity to invest in digitalization to revolutionize the real estate industry [ 74 ].

3.4.3 Real estate transactions

Real estate transactions involve the transfer of ownership of land, properties, and apartments and can be a costly and time-consuming. For example, on average, it takes about 22 days to complete a property transfer, costing around 5% of the total value (The World Bank 2018). Factors that contribute to delays in transactions include the unavailability of accurate or digital information, inefficient search criteria for customers, inconsistencies in parcel identification due to the difference between digitalized and paper plans, and the unavailability of standard inquiry forms or reporting mechanisms [ 90 ].

To address these challenges, an online land registry system is needed. This system is a conceptual and abstract model that includes four components: parties (individuals and organizations), administrative units (ownership rights), spatial units (parcels), and spatial sources (surveying) [ 42 , 55 ]. An efficient electronic system can better monitor the registration process, automatically prevent fraud, and alert by detecting typical fraud patterns [ 89 ]. These systems can save time, reduce workforce, minimize bureaucratic delays, improve convenience and public access to land registration, enhance search possibilities, and provide remote access to records or registers. Additionally, it can provide a trusted and reliable source of information for the public, property buyers and sellers, and other stakeholders [ 124 ].

3.4.4 Proptech innovation

Proptech, short for property technology, refers to integrating technology with real estate operations. It involves using technology to perform tasks, facilitate interactions between buyers and sellers, transform physical products and information into data and services, and support the organization of people [ 106 ]. The development of real estate digital technologies, commonly referred to as Proptech, is expected to have a transformative impact on the entire real estate industry [ 51 ].

Proptech, short for property technology, refers to integrating technology with real estate operations. It involves using technology to perform tasks, facilitate interactions between buyers and sellers, transform physical products and information into data and services, and support the organization of people. The development of real estate digital technologies, commonly referred to as Proptech, is expected to have a transformative impact on the entire real estate industry.

Large-scale real estate organizations are adapting to recent technological advancements by focusing on new technology platforms, tools, and paradigms [ 9 ]. Proptech enhances customer experiences, increases sales, and improves operational efficiencies (Nikolai Siniak, 2020). Baum (2017) divided the Proptech industry into three categories: Smart real estate (SRE), Shared Economy, and Real Estate Fintech. These categories encompass technology-oriented systems that make it easier to utilize, operate, or manage real estate assets and ownership transactions. The real estate framework includes automation, brokerage, digitization, and management processes that explain the overall impact of technology on the industry [ 106 ].

3.5 Data collection technologies

3.5.1 augmented and virtual reality.

Various data collection technologies have been utilized in digital real estate, such as virtual reality (VR), drones, and big data. Virtual and augmented reality (AR) are among the most common tools used in the industry [ 20 ]. Virtual reality (VR) creates virtual worlds without a spatial reference to the real world, while augmented reality (AR) combines actual life with digital reality by superimposing computer-created virtual objects, scenes, and systems on actual scenes to enhance reality. These technologies have evolved, and in 2017 alone, they attracted huge investments of around $13 billion [ 115 ]. By 2025, revenues generated from VR/AR software are expected to reach $2.6 billion, and the market of VR and AR is expected to reach at least $80 billion in real estate (Forbes Real Estate [ 21 ].

Real estate agencies are using AR technologies to enhance classified advertisements and real estate search functions (Fig.  9 ). AR and VR offer opportunities such as platforms of virtual property, directed and interactive visits, virtual presentations, architectural visualization, and virtual trade [ 34 ]. 3D-virtual tours can be accessed through VR headsets. Individuals wear these headsets over their eyes and the upper part of their faces, allowing them to be fully immersed in a virtual home [ 97 ]. AR has also caught the attention of design review and collaboration as it is suitable for creating an interactive 3D communication setting. It allows consumers to explore greater possibilities for design scenarios and more intuitively analyze 3D BIM models before they are physically constructed [ 46 ]. In this way, the end-user can get a sense of an asset before viewing it, increasing their confidence in purchasing such property [ 115 ]. The advantages of using such technologies include global transactions, time savings, addressing intangibility, and narrowing down the pool of interest for buyers (Forbes Real Estate [ 21 ].

Sub-Themes of data collection technologies

The current state of Augmented Reality (AR) technology is not without limitations. Technical issues such as difficulties in detecting real-time tracking sensors, user discomfort, and dissatisfaction with visual quality and display screens have been commonly cited as criticisms of existing AR displays. In response to these shortcomings, Spatial Augmented Reality (SAR) has been introduced as a potential solution. This technology uses an optical projector to alter the appearance of the real-world environment, providing a more immersive and realistic AR experience [ 46 ].

3.5.2 Drones

Drones, also known as unmanned aerial vehicles (UAVs), have become increasingly popular in the real estate industry for data collection purposes. These devices, which are operated through remote control or a ground control station, allow property managers and agents to capture aerial views of properties in the form of videos and images, which can then be used for marketing and promotional purposes [ 53 ].

In recent years, the use of drones in real estate management has increased significantly. They are used for various purposes, such as aerial photography, automated mapping, property marketing, 3D images, and the development of land surface data [ 71 ]. According to industry statistics, 72% of real estate companies in the United States, 52% in the United Kingdom, 48% in France, and 24% in Germany use drones for their business [ 53 ].

One of the major advantages of using drones in real estate is that they allow customers to view properties from an aerial perspective, providing them with a better understanding of the proximity of the property to neighboring houses and facilities without having to visit in person [ 115 ]. Customers highly value this feature, with 83% of home sellers globally preferring to work with agents who use drones. As a result, the selling rate of properties with aerial photographs taken by drones is 68% quicker than properties with normal photographs [ 130 ].

3.5.3 3D Scanning

3D scanning is a powerful data collection technique that is increasingly being used in the real estate industry to create accurate and detailed models, views, and images. This technology allows real estate stakeholders to access more reliable and credible data, which can be used for various purposes such as construction, renovation, and preservation [ 107 ].

Several types of 3D scanning technologies are available, including hand-held scanners, mobile scanners, and structured light scanners. Hand-held scanners, such as Lidar, are commonly used to create as-built drawings, which can be used to amend existing drawings or keep a record of maintenance and repairs. These scanners allow construction managers to update data and drawings using updated multi-dimensional models [ 92 ]. Scanned models can also be used to restore and preserve historical buildings, making them an important tool for real estate departments and government agencies [ 115 ]. These models can also be used in virtual tours and virtual walkthroughs, which can help to sell properties faster and more efficiently.

3.5.4 Wearable technology

Wearable technology, or wearables, refers to electronic devices or accessories that can be worn on the body and provide real-time data and information to the wearer. Due to their proximity to the body, wearables can provide more accurate and detailed information about a user and their surroundings [ 78 , 113 , 123 ].

In the real estate industry, wearable technology and devices can be used for various purposes, such as tracking maintenance and equipment records, providing visual cues for building elements, and presenting public data to potential customers [ 123 ]. The integration of wearable technologies with building management systems can also provide benefits such as fault detection and as-built drawings, allowing customers to make more informed decisions [ 115 , 91 ]. Similarly, in the construction industry, wearable technology can play a critical role in monitoring the well-being and safety of workers and equipment in real-time [ 96 ]. Wearable devices can be used to track workers' location, monitor their vital signs, and alert managers in case of any emergency. This can help improve the safety and efficiency of construction sites and protect workers from potential hazards.

3.5.5 Big data

Big data is complex and multidimensional, entailing overlaps with various data collection and analysis technologies. It refers to the large and complex data sets generated by various sources such as smartphones, computers, and social media [ 123 ]. These data sets are difficult to process and analyze using traditional software techniques, making big data management and analytics challenging and costly [ 52 ]. According to a report, nearly 95% of businesses produce unstructured data and spent $187 billion 2019 on big data management and analytics [ 7 ].

With the wide utilization of technology, the real estate industry has also become a data-driven sector. Big data is increasingly being used in various forms, such as visualization of properties [ 30 ], virtual and augmented realities [ 116 ], stakeholder management [ 113 ], and online customer management [ 73 ]. Big data can save time and resources by providing real-time information on property prices, rents, and customer needs [ 123 ]. It can also help real estate agents and property managers to find potential clients and make more informed decisions. Big data in real estate incorporates a wide range of databases that include transaction histories, sociodemographic data, and geo-referenced data [ 9 ]. This data can be used for research purposes to better understand urban dynamics and infrastructure management [ 108 ].

3.6 Data networking tools

3.6.1 cloud computing.

Networking refers to the ability of devices to connect and share resources on a network through wired or wireless connections. Various tools and technologies are available for networking and computing, including cloud storage, retrieval, and computing (Fig.  10 ). Cloud computing is a data networking technology that offers on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service [ 17 , 18 ]. In 2021, the global cloud market had a value of US$133.6 billion and is projected to reach US$168.6 billion by 2025 [ 63 ].

Sub-Themes of Data Networking Tools

In the real estate industry, cloud computing offers several benefits, such as cost-effectiveness, improved security, data tracking, enhanced customer relationships, and increased productivity [ 36 , 45 , 75 , 77 ]. For instance, cloud-based software and apps can help archive, store, and display real estate data for decision-making, reducing the risk of regret associated with insufficient information [ 115 ]. Additionally, it can assist in tracking and displaying maintenance and refurbishment records to stakeholders, providing them with financial details of the property. Furthermore, cloud computing improves scalability, flexibility, device integration, data security, and reliability [ 17 , 119 , 135 ]. Several studies have highlighted the use of cloud-computing services, such as Google App Engine, Microsoft Azure, Salesforce.com, Google Docs, Online Payroll, Cloudwatch, and Azurewatch, in the management of real estate [ 1 , 2 , 39 , 44 ]. The market share of cloud computing in the real estate industry is expected to grow to 9.7% in the next five years [ 60 ].

3.6.2 Internet of Things (IoT)

The Internet of Things (IoT) refers to the interconnected network of devices that can detect physical characteristics such as temperature, humidity, lighting, and other parameters [ 125 ]. It is a novel internet-based model that connects various things or objects in the environment through wireless or wired technologies to achieve specific goals [ 115 , 125 ]. The global market for IoT is projected to reach $875,000 million by 2025, with an annual compound growth rate of 26.9% [ 80 ].

In real estate property management, IoT devices are used to monitor buildings and associated environments to manage temperature, humidity, indoor air quality, and lighting levels [ 115 ]. IoT in real estate includes real-time production logistics synchronization systems and fog computing for wind farms, smart grids, and smart cities [ 11 , 83 ]. Almost 73% of real estate businesses have already adopted IoT. IoT is transforming the real estate industry through innovations such as house hunting, smart real estate homes, smart buildings, and management systems [ 68 ]. It can help to reduce operational costs, improve the quality of life, and provide additional security. In large sites such as industrial zones, office parks, shopping malls, airports, and seaports, IoT can reduce energy costs, improve spatial management, and lower building maintenance costs by up to 30% [ 93 ].

3.6.3 Software as a Service (SaaS)

Software as a Service (SaaS) is a model of providing software in the technology industry by offering remote access to software via web-based network services instead of installing it on the user's desktop. This remote access is provided through the internet, making it cost-effective for agents and users [ 123 ]. SaaS integrates various solutions by combining several property management services under one platform [ 115 ].

SaaS has been widely used in construction management, client care management, supplier management, marketing, retailing, and various administrative tasks [ 61 , 123 ]. SaaS-based software packages such as RealSpace and PropertyBase facilitate sharing information regarding contracts and work orders, lease and occupancy, maintenance, and security among key stakeholders, including consumers. This information reduces post-purchase regrets [ 115 ]. In the real estate industry, SaaS platforms typically offer key functions such as customer management, transaction management, property management, team management, listing management, and marketing automation [ 28 ].

The benefits of SaaS in the real estate industry include ease of accessibility, affordability, flexibility, cost-effectiveness, and ease of use. SaaS software can be accessed from anywhere, making it convenient for users. Additionally, as the software is provided as a service, it eliminates the need for high initial investments, making it cost-effective for businesses [ 4 ]. Furthermore, SaaS software is flexible and can be customized to meet specific needs, and it is easy to use, making it accessible to a wide range of users.

3.6.4 Blockchain

A blockchain is a decentralized and distributed database that stores ownership records in digital format through blocks linked together through cryptography. In the case of Bitcoin, transactions are recorded permanently and are viewable to anyone. Decentralized blockchains cannot be modified, and once entered, data is irreversible [ 40 ].

The real estate industry has relatively high profits but also faces significant issues such as high transaction fees, lack of transparency, time-consuming transactions, fraud, and undue commissions [ 3 , 129 ]. Blockchain technology has emerged as a powerful supporting technology to address these real estate investment market issues. It offers various benefits such as speed, reliability, immutability, traceability, transparency, decentralization, and trust [ 3 , 33 , 129 ]. Therefore, the need for a blockchain-based structure arises to execute efficient, tamper-proof, fast, fraud-free, and reliable property transactions.

Blockchain technology can act as a registry that records property rights (token title) and transactions. Due to this, it fits both legal traditions by keeping title records and chains of deeds [ 50 ]. To minimize the risk of fraud, personal digital keys are given to involved parties in a contract [ 3 ]. The technologies in blockchain include smart contracts, immutable record management, and time-stamped [ 3 , 33 , 49 , 50 ]. These technologies can ensure that property transactions are secure, transparent, and tamper-proof, which are essential for the real estate industry.

3.6.5 Property passports

A property passport, a digital logbook, is a unique digital file containing comprehensive information about an individual's property. This information is maintained and transmitted by the property owner and can include details such as the property's title, legal documents, and any relevant information about its occupants. To ensure that property passports are detailed, transparent, and cost-effective, it is essential to integrate advanced digital technologies such as IoT (Internet of Things) and BIM (Building Information Modeling) and automated means of managing occupants and properties. Real estate professionals have identified the implementation of property passports as a crucial step towards streamlining real estate transactions and reducing delays [ 90 ].

3.7 Decision making systems

Decision-making is critical to real estate property valuation, selection, purchase, or rental. From a financial perspective, purchasing property can be a significant investment with a high level of risk. Decision-making is typically based on three key criteria: household needs, building facilities, and location characteristics. Various decision-making systems and procedures have been developed to assist in this process, including geographic information systems (GIS) for evaluating locational characteristics, geostatistical analysis for identifying patterns in the data and building information systems (BIM) for describing building details and facilities. However, the most prevalent approach involves using artificial intelligence-based methods for real estate management (Fig.  11 ).

Sub-Themes of Decision-Making Systems

3.7.1 Building Information Model (BIM) and Geographic Information System (GIS)

Building Information Modeling (BIM) is a digital representation of the physical and functional characteristics of a building that creates a shared information resource for building information [ 27 ]. Originally introduced in the architecture, engineering, and construction (AEC) industry, BIM provides a reliable foundation for decision-making throughout the life cycle of a building, from initial conception and design to construction, operation, maintenance, and demolition [ 22 , 128 ]. The data and information available in digital format through BIM can be modified, replicated, and shared with project stakeholders [ 66 ,  88 , 104 ]. BIM and GIS can be used together to identify specific property units, accurately depict cadastral boundaries, and provide detailed representation of complex buildings [ 104 ].

BIM is a new paradigm for real estate that allows for the design, building, and management of built assets in a digital environment. It facilitates the flow of information throughout the project's life cycle and enables effective collaboration among all real estate stakeholders [ 13 ]. Using BIM has numerous benefits, including cost and time savings, improvements in quality and performance, detection of potential design conflicts, improved accuracy, enhanced collaboration and communication, better process of presentation and documentation, improvement in planning and design, and better visualization, cost estimation, facility management, and sustainability management [ 6 , 65 , 82 ].

A Geographic Information System (GIS) is a computing system designed for assembling, processing, and analyzing spatial data or information [ 26 , 62 , 103 ]. GIS has become vital in designing and planning real estate projects, particularly in community management. Using GIS, real estate professionals can measure the precise impact of location and make informed decisions based on that knowledge. GIS has become a widely used tool for property valuation by comparing the physical characteristics of a property, proximity, and network analysis [ 26 , 103 , 110 , 126 , 132 ].

GIS technology presents a means of implementing vastly improved land information systems, providing consistent, accurate, and timely data. GIS-based frameworks can support sustainable land use planning or land use scenario planning in the urban renewal of high-density cities, acting as an assessment tool to evaluate particular land sites and as a prototype of planning support systems [ 54 ,  114 ]. GIS tools can support and facilitate urban planners and other stakeholders involved in decision-making [ 23 ]. GIS data provides opportunities to locate regional real estate markets for new residential, retail, and industrial developments. It also provides an opportunity to improve real estate analysis by linking geographic location with data types such as demographics, customer profile, transport network, distance, employment, climate, etc. Large institutional investors such as real estate investment trusts, pension funds, life insurance companies, mortgage bankers, and international banks can utilize GIS databases to evaluate real estate investments in their portfolios [ 32 , 86 ].

3.7.2 Artificial Intelligence (AI)

Artificial Intelligence (AI) is the ability of computers and intelligent programs to perform complex tasks using various forms of rules and reasoning [ 87 ]. The field of AI is rapidly growing and is being adopted by various industries. According to industry estimates, global AI revenue is expected to reach approximately $126 billion by 2025 [ 64 ].

AI-based technologies have been extensively used in the fields of civil engineering, urban planning, and smart city domains. In the real estate industry, AI can assist real estate agents in filtering potential buyers by collecting information through data-mining search algorithms and marketing strategies. AI-based solutions can also connect buyers to their dream properties by applying filters to narrow their search and extract related attributes based on massive data sets through AI predictive analysis. This type of intelligent matching can help prevent consumers from making decisions they may regret [ 115 ]. AI will continue to play an important role in the real estate industry, becoming an instrument for value-added and innovative business models and products. Examples include automated data validation and evaluation, documentation review, benchmarking, and other analytical applications [ 14 ]. The use of AI in the real estate industry will help improve the buying and selling process, making it more efficient, accurate, and cost-effective.

3.8 The Digital Real Estate Transformation Framework (DReTF)

The Digital Real Estate Transformation Framework (DReTF) is a comprehensive approach that outlines the essential components of digital real estate. This framework emphasizes the importance of information communication technology, data collection, networking tools, and decision-making systems in facilitating a successful digital real estate transformation (Fig.  12 ). The Digital Real Estate Transformation Framework (DReTF) envisions these components of digital real estate through the adoption, integration, and implementation of specialized software and technologies.

The Digital Real Estate Transformation Framework (DReTF)

Adoption: Adoption is a crucial aspect of digital real estate transformation. As the field of real estate evolves rapidly, real estate professionals and firms need to learn and utilize the specialized software required for modern real estate practices. Real estate agencies must adapt to the digitization of consumer behavior to increase their competitiveness or meet the changing market demands. This can be achieved by staying current with digital updates and progress to remain competitive. Additionally, by placing sustainability and quality of life at the heart of their projects through technology and digitalization, real estate firms can generate a safer, healthier, and more fulfilling future.

Integration: Integration is another critical aspect of the DReTF, as it emphasizes the seamless integration of digital real estate technologies with website components to provide customers with useful tools for making decisions about selecting and purchasing a property. These tools can include inspection, view, and customization services. Digitalizing all available stored data related to the environment, transportation, landmarks, amenities, property/real estate, cadastral, legal affairs, planning, demographics, remote sensing, and mapping is essential. This can bring greater transparency to real estate transactions and protect individuals from fraudulent activity. Furthermore, digital developments should provide new forms of integration between physical and digital urban infrastructure, which can support future territorial and urban management and development.

Implementation: Implementation is the final component of the DReTF, which is hindered by various factors, including a lack of awareness, understanding, and capabilities among stakeholders, as well as a lack of support and willingness to adopt these technologies. Additionally, the high cost of software, hardware, and digital services poses a significant challenge for digital real estate. Moreover, in developing countries, data inaccessibility and availability also limit the adoption of digital technologies. Furthermore, as digital technologies evolve, so do the policies, regulations, standards, security protocols, and user privacy concerns surrounding their use.

To address these barriers, consumers need access to information that allows them to make informed decisions about using digital technologies in real estate. Governments can also play a key role in promoting the adoption of digital technologies in real estate by developing urban development plans and investing in ICT projects. This can help to enhance city operations and improve urbanization levels and efficiency. Additionally, governments should focus on promoting the digitalization of records at both the national and local levels and establishing clear regulations regarding real estate ownership data. By promoting innovation and expediting the widespread use of ICT services, governments can help to overcome these barriers and facilitate the adoption of digital technologies in the real estate sector.

4 Conclusion

The real estate sector is a significant contributor to global economies, and digital technologies are increasingly shaping the industry operations and customer behaviors in the real estate market. Digital technologies provide various decision support tools and services to various stakeholders, including real estate agents, developers, and consumers, which can enhance the proficiency and effectiveness of day-to-day operations, decision-making, cooperation, and monitoring.

This study has reviewed the current literature on digital technologies, data collection methods, network techniques, and decision-making tools in the real estate sector. It also addresses the possible barriers and benefits of adopting particular digital technologies in real estate. The study aims to provide a benchmark for practitioners, scholars, and policymakers to consider as they undertake work in the field of digital real estate.

It is worth noting that this study is limited to published literature on digital technologies used in real estate, and future research can expand on this by collecting primary data from real estate experts through structured or unstructured interviews to understand the implications of digital technologies in the real estate industry. Moreover, based on subjective judgment, themes identified might differ for similar analysis. Additionally, this study can be extended to investigate the impact of digital technology on consumer decision-making about purchasing a property through questionnaires.

Leveraging AI as a Business Advantage

2024 CREW Network Research Paper: How Women in Commercial Real Estate Can Use Artificial Intelligence to Advance Their Careers and Impact Company Success

In this research paper, CREW Network explores how commercial real estate (CRE) companies can leverage artificial intelligence (AI) to gain a business advantage—and how women in particular can use this technology to advance in the industry.  

Drawing on statistical data from more than 1,000 industry professionals, the paper includes insights on:  

how CRE professionals are using AI 

how CRE companies are using AI 

opportunities and challenges of using AI in commercial real estate 

the impact of the technology on the global workforce and its gender disparities and biases
