The Dutch housing market demands absolute transparency. Since April 2026, appraisers are legally required to verify and document foundation integrity (funderingslabel) and energy conservation details in every NWWI report.

At SlimmeTaxatie, you pay a single flat rate. No post-appraisal surprises, no hidden cadastre charges, and no express surcharges. We keep property valuation simple, transparent, and quick.
