Bidding
Making an offer, and what overbieden really costs
Updated August 2026
Dutch house-buying has no gavel. The asking price is an invitation, the seller is free to accept whichever offer they prefer — or none — and the process rewards understanding the rules more than nerve.
How an offer is actually made
You bid through the selling agent, in writing, and a bid is more than a number. It states the price, the conditions you attach, the completion date you want, and how long the offer stands. A seller weighing two similar prices will take the cleaner, faster one, which is why the non-price terms are worth as much thought as the figure.
An offer is not binding until both sides sign the koopovereenkomst. Once you have signed as a private buyer, you get three days in which you may pull out without giving a reason and without penalty.
Why overbieden is paid in cash
This is the part that catches people. A lender lends against the home’s appraised value, not against what you agreed to pay. Bid above the valuation and the difference is not borrowable: it comes from your own savings, on top of the kosten koper you were already finding.
So “how much can I overbid” is really the question how much cash do I have that is not already spoken for — and it is answerable before you attend a single viewing. The valuation happens after the agreement, which is why the financing condition below matters so much.
The conditions worth keeping
Two are common, and in a competitive market both are the first things buyers are tempted to drop:
- Voorbehoud van financiering — the financing condition, letting you withdraw if the mortgage does not come through. Waiving it means committing to a purchase you may not be able to fund, and the penalty for failing to complete is normally a percentage of the price.
- Bouwkundige keuring — a structural survey, and a condition that lets you renegotiate or withdraw if it turns up something serious. On a period property this is the difference between buying a known quantity and buying a roof you have not seen.
Dropping a condition is a real way to strengthen an offer. It is also a transfer of risk from the seller to you, and it should be a decision rather than a reflex.
Seeing where you stood
After a sale, agents will often share a log of the bids received, so an unsuccessful bidder can see how the decision was reached rather than guessing. It is worth asking for — over several attempts it teaches you more about a neighbourhood than any average will.
One thing this site can tell you outright: how long a home has been listed, and whether its asking price has already been cut. Both sit on every listing page, un-gated, under Transfer — time on the market is the most honest negotiating signal there is.
