When you browse Amsterdam listings you’ll see two little letters after many prices: “k.k.” It stands for kosten koper — “costs for the buyer” — and it’s one of the most important things to understand before you make an offer. Here’s what it really means for your budget.
What “kosten koper” actually means
Most existing homes in the Netherlands are sold kosten koper, meaning the buyer pays the costs associated with the purchase on top of the agreed price. (Newly built homes are often sold “vrij op naam” / v.o.n., where many of those costs are included instead.) So the headline price is not the full amount you’ll need.
The main costs to budget for
- Transfer tax (overdrachtsbelasting): a percentage of the purchase price paid to the government. Rates depend on the property and the buyer’s situation, and there can be exemptions for younger first-time buyers within certain limits — always confirm the current rules for your case.
- Notary (notaris) fees: for the deed of transfer and, if you have a mortgage, the mortgage deed.
- Valuation (taxatie): lenders require an independent valuation report of the home.
- Mortgage costs: mortgage adviser fees and any arrangement costs.
- Buying-agent fee (aankoopmakelaar): if you use a buyer’s agent to represent you.
- Structural survey (bouwkundige keuring): optional but often wise, especially for older buildings.
A worked example (illustrative only)
Imagine an apartment listed at a given price, kosten koper. On top of that price you’d add transfer tax, notary, valuation, mortgage and adviser costs, plus your buying-agent fee. Together these commonly add up to several percent of the purchase price. The exact total depends on the home, your mortgage and current tax rules — so the key habit is simple: never budget only the asking price.
Why this matters when you bid
Knowing your all-in number keeps your bidding disciplined. Buyers who budget only the listing price can find themselves stretched once the purchase costs land. Factor everything in up front, and you can bid with confidence and no nasty surprises near the notary.
