Mansion Research Adds New 'Land & House Map' Feature to its Map-Based Real Estate Search Service to Streamline Sourcing and Appraisal

Mansion Research Launches New 'Land & House Map' Feature for Real Estate Professionals

Mansion Research Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; CEO: Chikara Yamada) has officially released the 'Land & House Map' feature on April 7, 2026. This new addition expands the map-based search functionality of their 'Real Estate Data Cloud' service—previously limited to condominiums—to now include land and detached houses.

### Development Background: Accelerating Area Understanding for Sourcing and Appraisal

For real estate agencies and buy-back/resale companies, improving the accuracy of sourcing decisions and appraisal proposals to sellers requires a deep understanding of local market trends and transaction cases.

However, land and house transactions presented several challenges: - **Scattered Data:** Low consistency in data, making it time-consuming to grasp surrounding conditions. - **Opaque Supply-Demand Balance:** Difficult to intuitively understand price ranges and supply status by area. - **High Explanation Costs:** Preparing evidence for appraisals was laborious, affecting the quality of proposals.

To solve these issues, Mansion Research extended its map search feature—already popular for condominiums due to its ease of use on the go—to include land and detached houses.

### Features of the New 'Land & House Map' - **Visualizing Cases on a Map:** Intuitive grasp of market conditions for land and houses by area. - **Supply & Distribution Analysis:** Supports understanding the supply-demand balance at a glance. - **Improved Explanation Power:** Immediate presentation of surrounding cases during appraisals, increasing client satisfaction and persuasion. - **Optimal Analysis by Type:** Specialized analysis for condos, land, and detached houses. - **Consistent Decision-Making:** Supports the entire workflow from sourcing consideration to appraisal proposals.

### Use Cases - **Sourcing Consideration:** Rapid analysis and price judgment in unfamiliar areas. - **Sales Appraisal:** Presenting surrounding cases to clients with visual evidence for pricing. - **On-site Sales:** Quick, evidence-based responses to sudden consultations while out of the office, improving efficiency in document creation.

### Service Overview and Pricing 'Real Estate Data Cloud' is a sales support tool that allows users to freely search and view over 460 million historical real estate transaction records across Japan. It visualizes transaction history and price trends dating back over 10 years, enabling 'data-driven proposals' rather than relying on experience or intuition.

- **Target:** Real estate agencies, buy-back/resale companies, and professionals involved in sourcing, brokerage, and appraisal. - **Pricing:** Monthly from 2,000 JPY (excluding tax). *No additional cost for existing 'Real Estate Data Cloud' subscribers.
