Opkoopbescherming: why a recently bought apartment may not be legal to rent to you

When you finally get a viewing in Amsterdam or Rotterdam, the last thing on your mind is the landlord's purchase history. You're thinking about the deposit, the commute, whether the radiator works.

But here's something I've watched trip people up: in a lot of Dutch cities, a home bought in the last few years simply cannot be rented out. Not "it's complicated." Legally forbidden.

The rule is called opkoopbescherming — purchase protection. And if the person renting you that apartment bought it recently and below the city's price cap, you may be signing a lease that the municipality can come in and unwind.

So before you transfer a euro, two questions are worth their weight in gold: When did you buy this place? and Are you allowed to let it under opkoopbescherming?

The national government gave municipalities the power to introduce opkoopbescherming from January 2022. The goal was to stop investors with deep pockets from outbidding first-time buyers, snapping up affordable homes, and turning them into rentals.

The mechanism is blunt and effective. In designated neighbourhoods, if you buy a home below a set value, you have to live in it yourself for at least four years. Renting it out — long-term, short-stay, holiday let, doesn't matter — is prohibited during that window. There are only a handful of narrow exceptions.

What catches people off guard is that this applies regardless of the property's history. Even if the apartment was a rental before, a new owner buying below the cap is locked into self-occupancy. The slate gets wiped clean on sale.

By 2026, every Dutch city with more than 200,000 residents has some version of this in place. So this isn't a fringe rule affecting a few streets. It's the backdrop to a huge chunk of the market you're searching in.

The coverage is bigger than most renters realise. In Amsterdam, around 60% of the housing stock falls under opkoopbescherming. In Rotterdam it's about 27%, concentrated in the lower and mid-priced segments — exactly the homes internationals on a normal budget are competing for.

The threshold that decides whether a property is caught is the WOZ value — the official valuation the municipality uses for tax. Each city sets its own cap. Rotterdam's sits at €355,000. The Hague, where average prices run higher, uses a lower cap of €255,000 and only protects the most affordable homes. Amsterdam's cap covers most affordable and mid-market apartments.

So the apartments most likely to be illegal-to-let are precisely the ones renters most want: the affordable and mid-range ones. That's the cruel irony of this whole policy. The protection aimed at helping ordinary people buy has quietly shrunk the rental pool those same people depend on.

If you want to sanity-check a place, you can look up its WOZ value — it's public — and compare it to the city's cap. Below the cap plus a recent purchase date equals a red flag.

There's one detail that matters enormously if you're moving into a place that's already been a rental.

If a property was already let out at the time it was bought, and had been rented for more than six months, opkoopbescherming may not bite immediately — the new owner can keep that tenancy running. But if the home was vacant when sold, or rented for less than six months before the sale, the new owner cannot legally let it out at all.

This is where I'd push for a straight answer. If a landlord recently bought the place and it sat empty between purchase and your viewing, the maths often doesn't work in your favour. The lease they're offering you might not be one they're allowed to give.

And Amsterdam adds another layer on top. Many new-build apartments there carry perpetual no-renting clauses baked into their erfpacht — the ground lease. That's not a four-year restriction; that's potentially a lifetime ban on letting, enforced alongside the municipal rules. So even an owner who clears the opkoopbescherming hurdle can still be sitting on a property they're contractually forbidden from renting.

From 1 January 2026, Amsterdam goes further with a permit system for second homes — pied-à-terre properties that owners don't live in full-time.

Under the new rules, you need a municipal permit to own a second home, and it's only granted under strict conditions: you work in Amsterdam at least two days a week for six months, you provide informal care to an Amsterdam resident, or you lived in the city for at least three years before moving away.

Properties classified as social or mid-range regulated rental housing — those scoring 186 points or fewer under the WWS — aren't even eligible for a second-home permit. Existing owners can apply for a one-year transitional permit, but new buyers have to meet every criterion.

The city reckons there are 2,500 to 3,000 underused second homes it wants to free up. For renters, the takeaway is simple: the legal terrain under a recently bought Amsterdam apartment is now layered three deep — opkoopbescherming, erfpacht clauses, and the second-home permit. Any one of them can make your rental impossible.

Here's the uncomfortable part. The data shows opkoopbescherming has done what it set out to do on one narrow measure — investor purchases in Rotterdam's regulated neighbourhoods fell by around 75%, and roughly 2,000 homes nationwide went to first-time buyers instead of investors.

But look at who those buyers are. The typical first-time buyer under the new regime earns about €10,000 more than the tenants they replaced, is three years older, and is more likely to be Dutch-born. House prices, meanwhile, barely moved — the effect in Rotterdam was a negligible 0.1%.

So the rental supply got smaller without prices coming down. In Rotterdam's regulated areas, rents actually rose about 4% relative to non-regulated areas — roughly €50 a month more. Landlords anticipating tighter controls have been selling off rental properties, shrinking the pool further.

If you're an international arriving without a Dutch credit history, often without a BSN yet, competing for exactly the affordable and mid-market homes opkoopbescherming covers — you're feeling all of this at once. Fewer listings, higher rents, and a real risk that some of the listings you do find come from owners who can't legally let.

I'm not telling you to walk away from every place owned by a recent buyer. Plenty of legal rentals exist — sitting tenancies that transferred, homes above the cap, properties outside protected zones, owners with a valid exception.

What I am saying: ask. When did you buy this? Does opkoopbescherming apply here, and if so, do you have an exemption or a sitting-tenant situation? A legitimate landlord won't blink at those questions. Evasiveness is your answer.

Cross-check the WOZ value against the city cap. If you want certainty about your rights once you're in, the huurcommissie and the huurprijscheck are there for rent and points disputes — but they won't save you from a lease the municipality declares illegal because the owner was never allowed to let in the first place. Prevention beats the cleanup.

The reason House Hunter watches 1,000+ sites and pushes listings to you the moment they appear is exactly this: speed gives you room to be choosy. When you're not the desperate 80th applicant, you can afford to ask the awkward purchase-date question and wait for a place where the answer holds up.

The apartment that looks perfect on the viewing isn't worth much if the city can pull the lease out from under you. Ask early, verify the WOZ, and treat a recent purchase below the cap as a question to resolve — not a detail to ignore.
