In the free-sector rental market, a Randstad tenant often pays more per month than the net mortgage cost on a comparable home. That is down to mortgage interest deduction, and to the fact that your repayment builds equity rather than disappearing. On monthly cost alone, buying wins surprisingly often.
Monthly cost is not where the decision sits, though. Buying costs a one-off 4–6% in buyer’s costs, and selling costs agent commission and notary fees again. Together, reckon on roughly 6–8% of the property value going on the transaction itself. You only earn that back through price growth, or through the years you lived more cheaply than renting.
Hence the practical rule of thumb: buying generally pays from about five years. If you already know your contract ends in two years and you will probably leave the country, renting is almost always the wiser call — even when the rent feels steep.
There is no nationality or residency requirement to buy property in the Netherlands. You need a BSN and a Dutch bank account, and lenders look at your income, your contract type and your residence status. On a temporary contract or a time-limited residence permit, your maximum mortgage may come out lower, or the bank may ask for additional security.
Mind the 30% ruling if you have it. It raises your net income but expires, and most lenders assess your gross salary anyway. Base your monthly commitment on what you keep after the ruling ends, not on the figure currently landing in your account.
One trap that catches expats out: you cannot simply rent out the home you bought if you go abroad for a while. Municipalities with buy-to-let protection impose a self-occupancy obligation, and your mortgage terms generally forbid letting without the bank’s consent. If there is a real chance you leave within a few years, weigh that in.
The rental market itself makes the calculation less optional than it looks. Free-sector supply in the big cities is scarce and turnover is low, and a tenancy gives you little long-run certainty about your housing costs. That is a genuine argument for buying sooner than the plain five-year rule suggests — not because buying is cheaper, but because it buys you control over what you pay five years from now.
Look at the shape of your mortgage too. To qualify for interest deduction you must repay on an annuity or linear basis within a maximum of thirty years. An annuity mortgage starts with low repayment and high interest, which maximises your deduction early but builds little equity; a linear one costs more per month at the start but pays down faster. If there is any chance you sell within five years, that equity build-up is exactly what decides whether you walk away without residual debt.
Finally, the scenario people skip: selling into a falling market. Buy with little of your own money in, watch the market drop 10%, and your equity is gone — you finish the sale owing a residual debt you still have to repay. That risk is manageable if you stay long and small if you put substantial cash in, but it is why the five-year rule is not accounting nicety so much as a buffer against bad timing.
