What is the difference between a Desktop Valuation and an NWWI Appraisal?
A Desktop Valuation is a 100% digital estimate (€95) completed remotely without an appraiser visiting your home. This is only allowed for refinancing low-loan-to-value mortgages. A full NWWI Appraisal (€650) is an official, comprehensive on-site inspection where a certified appraiser thoroughly examines your property. This report is mandatory for home purchases and major renovations and is accepted by all lenders.

When determining your property's value in the Netherlands, you will notice significant price differences. A remote digital valuation (the Desktop Valuation) costs just €95. In contrast, an extensive, fully validated report by the NWWI averages €650. When can you choose the cheaper digital option, and when is the full on-site appraisal legally required? We explain the rules simply below.

The Digital Desktop Valuation (€95)

The Desktop Valuation is a modern, fast way to value your home. No physical property visit is conducted. Instead, a statistical model estimates the property's market value. This is calculated using official records from the Kadaster (Land Registry) and transactional data of comparable sold properties in your direct neighborhood.

A certified Dutch register-appraiser reviews the automated calculation remotely and signs off on it. The process is typically finalized within 4 hours at a minimal cost. However, keep in mind: Dutch mortgage lenders rarely permit this method for securing property financing.

Expert Inzicht
A digital Desktop Valuation is cheap (€95). However, Dutch mortgage lenders rarely accept it for official financing. It is legally prohibited when purchasing a property, funding a renovation with a construction deposit, or refinancing for energy efficiency upgrades. Furthermore, it is not allowed if your total outstanding loan exceeds 90% of the property's market value (LTV). For 100% security, lenders require a comprehensive, on-site NWWI appraisal.

The Full NWWI Appraisal (€650)

The validated NWWI report is the absolute gold standard in the Dutch housing market. A certified, local appraiser physically visits your property to conduct a meticulous inspection. They examine the entire home: from the foundations and crawl space to the roof insulation, overall maintenance state, and energy rating details.

Following the inspection, the appraiser compiles a highly detailed valuation report. The Nederlands Woning Waarde Instituut (NWWI) rigorously validates the document. This double-check ensures the accuracy and objectivity of the valuation, making the report 100% guaranteed to be accepted by all lenders.
