The Bidding Process in the Netherlands

How Dutch bidding actually works: negotiation versus closed tender, the five decisions in every offer, the valuation ceiling that caps your bid, and what waiving conditions really costs.

The asking price of a Dutch house is a marketing decision, not a price. Some are set optimistically and the house sells below them; others are set deliberately low to draw a crowd and the house sells well above. Your job as a buyer is to work out what the house is worth, how much you can actually pay, and how much risk you are willing to carry — and only then what to bid.

The market you are bidding into

The market has loosened noticeably since the peak. In the second quarter of 2026 the NVM recorded a record ~57,000 existing homes newly listed and 45,200 sold, with the average transaction price at €506,000. Overbidding nationally has been running at roughly 4–5% above the asking price, far below the figures of a few years ago, and there is real room to negotiate in more places than there was.

Treat national averages as background only. Overbidding is wildly uneven between a canal flat in Utrecht and a 1970s house in Drenthe, and the number that matters is what comparable homes on that street actually sold for — not what they were listed at.

Two bidding formats

Individual negotiation (onderhandeling). You make an offer; the seller accepts, rejects or counters. You are only formally 'in negotiation' once the seller counters or says so explicitly — which matters, because until that point the agent will keep showing the house and taking other offers.

Closed tender (inschrijving). When interest is heavy, the agent sets a deadline and asks everyone for a single best-and-final offer. You bid blind, and there is no second round, so a strategy of opening low to see what happens simply loses the house.

The seller does not have to accept the highest bid

This is gunning — the seller's free choice of whom to sell to, and whether to sell at all. A lower bid with no conditions, a flexible transfer date and a buyer who is visibly able to complete often beats a higher bid that depends on a mortgage still being approved. The seller can also reject every offer and relist. Nothing you do obliges them to sell to you.

An offer is five decisions, not one

The ceiling nobody mentions until it is too late

A Dutch mortgage is capped at 100% of the home's market value as established by a formal valuation (taxatie) — not at the price you agreed. Every euro you bid above the valuation has to come out of your own savings, on top of the 4–6% you already need for the buying costs.

Worked example. Asking price €400,000, you win at €420,000, the valuation comes back at €405,000.

Had the valuation matched your bid you would have needed €21,000. So the €20,000 overbid did not cost you €20,000 of extra borrowing — it cost you €15,000 of savings you may not have. This is the most common reason a winning bid falls apart afterwards, and it is why "how much should I overbid?" is really the question "how much cash do I have left after the costs?"

Home Valuation (Taxatie) explains how that figure is arrived at, and Mortgage Requirements covers the income ceiling that applies at the same time. The lower of the two ceilings is the one that binds. To put your own numbers on this before you make an offer, the overbidding calculator shows exactly how much of a given bid would have to come from your savings.

Resolutive conditions, and what waiving them really costs

The financing clause (voorbehoud van financiering) lets you walk away if you cannot arrange a mortgage, typically within four to six weeks of signing. It is not automatic. You have to invoke it in writing before the deadline, and the standard contract requires you to substantiate it — normally with rejection letters from lenders. Miss the deadline and the clause is spent.

Waiving it is the most common way to win a bidding war and the most expensive way to lose one. The standard NVM purchase agreement carries a penalty of 10% of the purchase price if you fail to complete. On a €400,000 house that is €40,000 — and the 10% deposit or bank guarantee exists precisely so the seller can collect it. Do not drop the financing clause on the strength of an online maximum-mortgage figure. Drop it only if you hold a binding mortgage offer, or if you could complete without a mortgage at all.

The inspection clause (bouwkundige keuring) lets you withdraw or renegotiate if a survey finds more than an agreed amount of necessary repair. In a competitive market the stronger move is to have the survey done before you bid — a few hundred euros — so you can bid without the clause while still knowing what you are buying. Purchase Agreement Clauses covers the wording in detail.

Nothing is binding until both sides have signed

For a private buyer, a verbal agreement to buy a home is not enforceable: the schriftelijkheidsvereiste requires a written contract signed by both parties. Until that happens either side can still walk away — including a seller who accepted your bid over the phone. This cuts both ways, and it is why offers are sometimes still being taken on a house that is already 'sold'.

Once both parties have signed, the statutory cooling-off period (wettelijke bedenktijd) begins: three days, of which at least two must not be a Saturday, Sunday or public holiday, starting the day after you receive the signed contract. Within it you can cancel with no reason given and no penalty. It is the last free exit in the process — use it to read everything properly. See The Purchase Agreement.

Platforms and the bid log

Bidding is largely digital now, through platforms such as Move.nl, Eerlijk Bieden and Biedboek.nl. Agents bound by NVM or VBO rules keep a bid log (biedlogboek), and participants can ask for it once the sale completes. It is a reasonable check on whether the process was run straight, so ask for it if the bidding felt odd.

Do you need a buying agent?

Not legally, and not always. What an aankoopmakelaar buys you is access to what comparable homes actually sold for, a read on the local market, and someone to run the tender on your behalf. Expect a fixed fee of a few thousand euros, sometimes a percentage of the price, sometimes partly contingent on success.

It is most worth it if you are new to the country, bidding in a competitive city, or buying an older property where the survey really matters. It is least worth it if you know the area well and the local market is slow. Either way, remember that the seller's agent works for the seller — they are not a neutral party, however helpful they are.

Deciding your number

A workable sequence, in this order:

  1. Get your borrowing capacity confirmed by an adviser, not by a website.
  2. Count your cash and subtract the buying costs. What is left is your overbid budget, and it is a hard limit.
  3. Ask the agent what comparable homes sold for, and judge the asking price against those rather than against a neighbourhood average.
  4. Decide the number above which you would rather lose the house — before the deadline, written down, to yourself.
  5. Bid it, with only the conditions you can genuinely afford to drop, and accept that you will lose some.

Losing a bid costs you nothing. Winning one you cannot finance costs up to 10% of the purchase price. That asymmetry should shape how you bid.
