Hidden Costs of Buying: The €15,000+ Nobody Warns First-Time Buyers About

Thomas Bakker

Mortgage & finance specialist·Updated July 5, 2026

Kosten koper (buyer's costs) are the additional costs on top of the purchase price when buying an existing home in the Netherlands, and since a mortgage covers at most 100% of the property value, they must come from savings. Excluding transfer tax they run 3-5% of the price: notary fees (€1,200-2,500), valuation (€500-800), mortgage advice and arrangement (€2,000-3,000), a structural inspection (€400-800), and a buying agent if you use one (typically €1,500-4,500 fixed). Transfer tax then sits on top at the rate your situation attracts — 0% for a qualifying first-time buyer under 35 below €555,000, 2% for other owner-occupiers, 8% for investors — taking the all-in total to roughly 3-5%, 5-7% or 11-13%. On a €450,000 home an owner-occupier is looking at about €22,000-32,000. Buyers who discover these costs late are forced to shrink their bid, or abandon a purchase they have already committed to.

The purchase price is just the beginning. Between transfer tax, notary fees, valuation costs, and ongoing expenses, budget 3-5% of the purchase price for costs other than transfer tax, then add the transfer tax your situation attracts—0% as a qualifying first-time buyer, 2% as an owner-occupier, 8% as an investor—which takes the total to roughly 3-5%, 5-7% or 11-13% respectively, plus monthly expenses that many first-time buyers underestimate.

Reality Check

  • • €400k property = €24k-40k in closing costs
  • • Monthly costs average €400-600 beyond mortgage
  • • First-year maintenance: budget 1-2% of property value
  • • Emergency fund: 6 months of total housing costs

Frequently Asked Questions

How much are buyer's costs (kosten koper) in the Netherlands?

Plan for 3-5% of the purchase price for notary, valuation, mortgage advice, inspection and a buying agent, then add your transfer tax rate on top. That is roughly 3-5% all-in for a qualifying first-time buyer paying 0%, 5-7% for an owner-occupier paying 2%, and 11-13% for an investor paying 8%. None of it can be borrowed.

Can I include buyer's costs in my mortgage?

No. Dutch mortgages are capped at 100% of the appraised property value (106% only for documented energy improvements), so kosten koper must come from your own savings.

What ongoing costs do new homeowners forget?

OZB property tax, water board charges, VvE service costs for apartments, building insurance, and maintenance (rule of thumb: 1% of the home value per year). Together these often add €300-600 per month beyond the mortgage payment.
