Digital Real Estate Appraisal: Scraping Open Data for Accurate Valuations

Case Study


A client in the real estate sector needed to periodically retrieve diverse data from Dutch municipal websites regarding property status.
The objective was to standardize this heterogeneous information into a high-quality dataset, enabling accurate property valuations for market transactions and strategic decision-making.

The Solution


We developed an integrated solution featuring:

  • Scraping Agents: Automated tools to extract data from various Dutch municipal open-data portals, ensuring continuous updates
  • Data Normalization: Processing and standardizing collected data into a uniform, analyzable format
  • Property Valuation Algorithms: Support in developing advanced models for property price estimation, leveraging normalized data and market-specific variables
  • Seamless Process Integration: Direct system integration to export real-time property valuations and enhance strategic decision-making

The Benefits

  • Continuous Updates: Real-time access to official data ensures property valuations remain accurate and up to date
  • Precise Valuations: Standardized data and advanced algorithms improve appraisal accuracy, enhancing market competitiveness
  • Operational Efficiency: Automation reduces manual workload and minimizes errors in data collection and analysis
  • Strategic Decision-Making: Reliable data and predictive analytics support more informed, data-driven real estate transactions


This case study demonstrates how integrating scraping technologies with valuation algorithms can revolutionize real estate decision-making, ensuring precision and continuous updates for optimized strategies.
