[Modes for carrying out the invention]

[0022] The following describes each embodiment in detail with reference to the attached drawings. In this example, publicly known technologies are omitted from the explanation. Furthermore, the devices and methods described are illustrative examples for realizing the technical idea of ​​the invention, and the technical idea of ​​the present invention is not limited to those described below. The technical idea of ​​the present invention can be modified in various ways within the scope of the claims. In particular, it should be noted that the drawings are schematic and may differ from reality.

[0023] Figure 1 is a schematic diagram of the real estate information management system 1 of this embodiment. The real estate information management system 1 of this embodiment is a system that connects a seller site (computer, PC, etc.) 10 of the owner of the real estate who is selling the property, a seller's related company site (computer, PC, etc.) 20 of the seller (sales brokerage, PM (supports real estate management on behalf of the owner), BM (role of managing the building), design and construction company's computer, PC, etc.), a buyer's brokerage site (computer, PC, etc.) 30, a buyer's site (computer, PC, etc.) 40, a buyer's related company site (computer, PC, etc.) 50 of the buyer (computer, PC, etc.), a real estate information management site (computer, PC, etc.) 60, and a 3D modeling program provision site (computer, PC, etc.) 70 via a communication network (Internet Protocol) 80. Here, in Figure 1, there are multiple seller sites 10, seller's related company sites 20, buyer's brokerage site 30, buyer site 40, and buyer's related company site 50, but they are shown as one each.

[0024] Figure 2 is a schematic program configuration diagram of the control unit 62 of the real estate information management system 1 in this embodiment.

[0025] As shown in Figure 2, the control unit 62 of the real estate information management site 60 includes a seller-side real estate information acquisition unit 601 that acquires real estate information from the seller site 10 and stores it in the storage unit 63, a buyer-side information acquisition unit 602 that acquires real estate information from the buyer site 40 and stores it in the storage unit 63, a 3D modeling program acquisition unit 603 that acquires a program for generating a 3D model, a various information association unit 604 that acquires individual information from the seller's affiliated company site 20, the buyer's intermediary site 30, and the buyer's affiliated company site 50 and stores it in the storage unit 63, a designated location information provision unit 605 that provides real estate information and individual information for selected locations in the 3D model, and a storage unit 63, etc.

[0026] Refer to Figure 3. This shows the overall flow of this embodiment.

[0027] In Step S1, as shown in Figure 4, the seller site 10 considers the sale. The seller site 10 includes sales, BPM (business process management), and construction. Ultimately, the decision is made by the decision-maker.

[0028] Step S2 involves establishing an investigation system. As shown in Figure 5, this will be done based on brokerage, ER (real estate valuation), BPO, etc.

[0029] Step S3 involves conducting a property survey. As shown in Figure 6, the seller's considerations include economic, legal, and physical aspects.

[0030] Step S4 involves verifying the survey results. Specifically, as shown in Figure 7, economic items, legal items, and physical items are verified.

[0031] Step S5 involves reviewing and correcting the property. As shown in Figure 8, this is done based on factors such as brokerage, property management (PM - supporting property management on behalf of the owner), building management (BM - managing the building), construction, and property valuation (ER - properly evaluating the property). Then, a decision is made on the feasibility of each item, including economic, legal, and physical aspects.

[0032] In step S6, as shown in Figure 9, property documentation is prepared based on the corrected items for each economic, legal, and physical category.

[0033] In step S7, buyer site 40 reviews the property. This is done through an intermediary, as shown in Figure 10.

[0034] In Step S8, the buyer site 40 verifies important details. This is done based on PM, BM, and construction, as shown in Figure 11.

[0035] In step S9, the final agreement is concluded between the seller and the buyer. This is done by the respective settlement authority for the seller and the buyer, as shown in Figure 12.

[0036] In step S10, a contract is concluded between seller site 10 and buyer site 40.

[0037] Refer to Figure 13. Once a contract is concluded as described above, the following characteristics arise. Specifically, since the economic, legal, and physical items shown in area A are examined, comprehensiveness of information is ensured.

[0038] Refer to Figure 14. As shown in area B, the accuracy of the information is judged for economic, legal, and physical items, thus ensuring the accuracy of the information.

[0039] Refer to Figure 15. As shown in Area C, the information is based on seller, broker, PM, BM, construction, and ER, ensuring the integrity of the information.

[0040] Refer to Figure 16. As shown in Area D, information is made public based on the buyer, intermediary, PM, BM, construction, etc., thus ensuring information sharing and clear indication of approval or disapproval.

[0041] Refer to Figure 17. As shown in Area E, the above can be achieved through a multi-stakeholder platform.

[0042] Here, we will provide specific examples of information for economic, legal, and physical items. This information constitutes real estate information when entered by the seller site 10 and the buyer site 40. Furthermore, it becomes individual information when entered by the seller site's affiliated company site 20, the buyer's intermediary site 30, and the buyer site's affiliated company site 50.

[0043] Refer to Figure 18. Economic items such as officially announced land price, standard land price, inheritance tax land price, fixed asset tax land price, rental income, and operating expenses are entered by the guest (seller's affiliated company site 20, buyer's intermediary site 30, buyer's affiliated company site 50) or the seller.

[0044] Refer to Figure 19. Legal items include, for example, the boundary between the first floor of the building and the adjacent property has not been determined. There is no renewal agreement for the lease contract. The guest (seller's affiliated company site 20, buyer's intermediary site 30, buyer's affiliated company site 50) and the seller enter the information regarding the Building Standards Act (smoke vent windows are not tall enough), the Building Standards Act (parking lot roof is added to building coverage), the Fire Service Act (emergency lighting is out), the Fire Service Act (emergency lighting is out), etc.

[0045] Refer to Figure 20. Furthermore, as legal matters, the boundary between the second floor of the building and the adjacent property cannot be determined. There is no renewal agreement for the lease contract. The guest (seller's affiliated company site 20, buyer's intermediary site 30, buyer's affiliated company site 50) and the seller will enter information regarding the Building Standards Act (smoke vent windows are not tall enough), the Building Standards Act (parking lot roof is added to building coverage), the Fire Service Act (emergency lighting is out), the Fire Service Act (emergency lighting is out), etc.

[0046] Refer to Figure 21. Physical items include soil contamination, ground survey data, water leaks, mold on the ceiling, peeling wallpaper, and confirmation of the long-term repair plan, which are entered by the guest (seller's affiliated company site 20, buyer's intermediary site 30, buyer's affiliated company site 50) and the seller.

[0047] Figure 22 is a sequence diagram illustrating the schematic operation of this embodiment.

[0048] First, the seller site 10 accesses the real estate information management site 60 and transmits real estate information. This real estate information is stored in the storage unit 63 by the seller's real estate information acquisition unit 601 (a10, a12).

[0049] Individual information transmitted from other sites (seller's affiliated company site 20, buyer's affiliated company site 50, buyer's intermediary site 30) is received and stored in the storage unit 63 (a14, a16). Meanwhile, the buyer's site 40 transmits a request to obtain information related to real estate (a18).

[0050] On the real estate information management site 60, the 3D model acquisition unit 603 acquires a 3D model from the 3D model provision site 70, generates a 3D model of the real estate, and stores it in the storage unit 63 (a20, a22, a24). Here, the 3D model includes parts of the real estate that are not normally visible (for example, underground piles). In addition, photographs and other images are linked to the 3D model to form a digital twin.

[0051] Then, the various information association unit 604 reads real estate information and individual information from the storage unit 63 and assigns them to the corresponding parts of the three-dimensional model (a26, a28).

[0052] At the request of buyer site 40 (a30), the designated location information provision unit 605 searches for a three-dimensional model of the property that buyer site 40 wishes to purchase (a32). The designated location information provision unit 605 then transmits the retrieved three-dimensional model to buyer site 40 (a34, a36).

[0053] Buyer site 40 further requests disclosure of unclear property information (a38). Accordingly, property information management site 60 creates a three-dimensional model of the designated portion of the three-dimensional model (d40), adds property information or individual information (added as important information), and transmits it to buyer site 40 (a42, a44).

[0054] Similarly, if the seller site 10 requests disclosure of unclear property information, other sites (for example, the seller's affiliated company site 20, the buyer's affiliated company site 50, and the buyer's intermediary site 30) will add individual information to the three-dimensional model (a46, a48). In this way, a digital twin of the property is generated.

[0055] Refer to Figures 23 to 25. These are sequence diagrams that explain the detailed operation of the parts that were omitted from the explanation in Figure 22. First, the seller's website 10, which is the property owner, registers as a user (d1).

[0056] Then, seller site 10 accesses the login page and enters login information (d2, d3). Next, it displays the list of owned properties on the top page (d4).

[0057] Similarly, users must register on the seller's affiliated company websites (sales brokerage, PM, BM, design and construction companies) 20, the buyer's brokerage websites 30, the buyer's websites 40, and the buyer's affiliated company websites (PM, BM) 50. Then, access the login page and enter your login information. Next, view the list of owned properties on the top page (d12~d15, d19~d22, d28~d31, d35~d38).

[0058] Then, seller site 10 proceeds to the individual property details page (d5). Seller site 10 displays the property's digital twin (3D model) and detailed property information (d6).

[0059] Seller site 10 grants the seller's affiliated company site 20 access rights to the property details page (d7).

[0060] The seller's affiliated company website 20 provides access to the property details page (d16).

[0061] The seller's affiliated company site 20 posts important information items within the 3D model and sets important information items linked to location information (d17).

[0062] Seller Site 10 reviews the posted important information (d8). If Seller Site 10 finds any issues with the content (d9), it conducts a Q&A session. Seller's affiliated company Site 20 responds to the Q&A (d18).

[0063] Seller site 10 grants buyer site 30 permission to access the property details page (d10). Buyer site 30 accesses the property details page (d23).

[0064] Buyer site 30 confirms important details and answers questions (d24). Seller site 10 confirms and responds to questions (d11).

[0065] The buyer's site 30 grants the buyer's site 40 access to the property details page (d25). The buyer's site 30 provides an explanation of important matters to the buyer's site 40 and the buyer's affiliated company site 50 (d26).

[0066] Buyer site 40 accesses the property details page (d32).

[0067] Buyer site 40 grants the buyer's affiliate sites (PM, BM) 50 permission to access the property details page (d33).

[0068] Then, important matters are confirmed (d34). If there are any questions, the buyer's intermediary site 30 will reply with the answers (d27). Also, the buyer's affiliated company site 50 accesses the property details page (d39). Then, important matters are confirmed (d34).

[0069] Finally, seller site 10 and buyer site 40 agree (d40).

[0070] Refer to Figure 26. The seller's site 10, the seller's affiliated company's site 20, the buyer's intermediary's site 30, the buyer's site 40, the buyer's affiliated company's site 50, or the real estate information management site 60 all include a comment input field, and comments are added to the digital twin. Then, important matters are extracted from the comments and automatically created as data P for the important matters explanation document.

[0071] As described above, the present invention improves the accuracy and comprehensiveness of information. Specifically, each stakeholder directly inputs information on the web, and the building information is linked and mapped to the 3D scan data. This allows for centralized management of a wide range of information, including building compliance, repair history, rights, management status, inspection records, and corrective actions. It enables the creation of accurate important matters documents. Specifically, by incorporating the seller's approval flow into the system, it is possible to create more accurate and reliable important matters documents. It enables efficient information management through 3D display. Specifically, even for large-scale properties, utilizing 3D display allows for an overview of the entire property, resulting in efficient information management.

[0072] Detailed property assessment is possible from a distance. In other words, by using a three-dimensional model, it becomes possible to understand the detailed condition of properties even when they are located far away. This will streamline communication when overseas funds purchase Japanese real estate, reduce the need for on-site visits, and significantly reduce time and costs. Collaboration with experts will be promoted. In other words, collaboration with experts from different fields, such as architects and equipment specialists, will become smoother, enabling a more accurate understanding of the property.

[0073] This platform, centered on three-dimensional models, completely digitizes the process of creating research materials for important real estate disclosures, significantly contributing to increased efficiency and transparency in real estate transactions as a whole. Furthermore, by utilizing the building information created once, it streamlines real estate management and accelerates the digital transformation of the industry.

[0074] Major real estate brokerage firms can streamline the creation of important disclosure statements and improve communication with customers. By utilizing 3D models and detailed property information, even complex properties can be explained clearly. This speeds up transactions and improves customer satisfaction. Real estate funds and REITs can improve the accuracy of investment decisions through detailed property information, understanding property conditions from remote locations, and high-precision 3D models and detailed data. Furthermore, it becomes possible to understand the detailed conditions of properties located remotely, leading to an expansion of investment opportunities. Building management companies, architects, construction companies, and equipment specialists can provide property information that reflects their expertise. By integrating the knowledge of each specialist, it becomes possible to evaluate properties from multiple perspectives. This enables more precise property management and the development of renovation plans.

[0075] Although each embodiment has been described in detail above, the invention is not limited to any particular embodiment, and various modifications and changes are possible within the scope described in the claims. Furthermore, it is possible to combine all or more of the components of the embodiments described above. [Explanation of symbols]
