Buying in the Netherlands?
Bidding without data
You don’t know what the property is actually worth — or whether the asking price is fair for the neighbourhood.
Most properties sell above asking price, sometimes up to 10% over.
Hidden risks you can’t see
Foundation problems, asbestos, outdated wiring — Dutch pre-war buildings have specific risks that aren’t in the listing.
Structural issues can cost tens of thousands to fix — and sellers aren’t required to disclose everything.
VvE and ground lease pitfalls
The VvE (homeowners association) and erfpacht (ground lease) are unique to Dutch property — and can add thousands in hidden annual costs.
Most Amsterdam apartments are on ground lease, and many VvE funds are underfunded.
