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.
