Brainbay Modelwaarde API

Brainbay's Model Value API grants access to highly accurate home valuations across the Netherlands. As a subsidiary of the NVM (the largest Dutch association of real estate brokers), Brainbay possesses a unique data advantage: direct access to the NVM's comprehensive database of property transactions and specific housing characteristics.

This proprietary data allows the Brainbay AVM to factor in detailed property features — such as interior condition, specific renovations, and real-time market dynamics — that are often missing from public registries like the Kadaster. The API returns a model value, comparable reference properties, and a confidence score.

The API is extensively utilized by mortgage lenders for automated desktop valuations, by real estate investors for portfolio monitoring, and by appraisers as a reliable baseline for property valuation reports.
