Amsterdam's Anti-Buy-to-Let Rule Is Quietly Killing the Mid-Market Rentals Internationals Need

When the Dutch government introduced opkoopbescherming in 2022, the logic sounded airtight. Investors were outbidding first-time buyers, neighborhoods were losing their owner-occupiers, and something had to be done. So municipalities got the power to ban investors from buying homes below a set WOZ threshold and renting them out. Buy the place, live in it, or don't buy it.

In Amsterdam, that threshold now covers roughly 60% of the city's housing stock. If you buy a home under the cap, you must live in it for at least four years. No long-term rental, no short-stay, no holiday let. A few narrow exceptions exist — letting to direct family, or temporary rental during an overseas assignment — but that's it.

The problem isn't the intention. It's the chain reaction nobody in The Hague seems to have modeled.

The numbers are stark. According to Capital Value Research, the share of mid-rental homes in the Dutch rental market dropped from 18% in Q1 2022 to just 12% by Q3 2025. In Amsterdam specifically, the share of homes owned by private investors fell from 7.4% to 6.2% between 2023 and 2026 — a loss of about 5,000 rental homes, concentrated in exactly the affordable segments where supply was already tight.

Those homes didn't disappear. They got sold to owner-occupants. Which sounds fine until you realize who was renting them.

Internationals and young professionals. People who don't qualify for social housing because they earn too much, and can't buy because they don't have a Dutch credit history, a BSN, or the €40,000+ down payment the mortgage market demands. They're now competing for a shrinking pool of legal mid-market listings, many of which get snapped up within hours of appearing on Pararius or Funda.

We see it in the data we process at House Hunter every day. The mid-market listings that do appear are gone faster than ever, and the ones replacing them are priced well above what most internationals can afford.

Here's where it gets uncomfortable. Dutch researchers found that in Rotterdam's regulated neighborhoods, investor purchases fell by 75%, and about 2,000 homes nationwide went to first-time buyers instead of investors. That's a real number, and it represents real people who got a foothold in ownership.

But those first-time buyers are typically older, earn about €10,000 more than the tenants they replaced, and are more likely to be Dutch-born. The policy didn't open doors for lower-income or international residents. It shifted ownership from landlords to a slightly more affluent, native-born demographic.

Meanwhile, the renters who were displaced — the people who were actually living in those 5,000 Amsterdam homes — got pushed into a market with fewer options and higher prices. In regulated areas of Rotterdam, rents rose about 4% relative to non-regulated areas, roughly €50 more per month. In Amsterdam, more than 42% of private rentals are now priced above €2,000 per month, and private-sector rents rose 7.3% in Q1 2026 alone.

Nearly 1,900 more rental homes left the Amsterdam market than entered it during that same period. The pipe is draining faster than anyone's refilling it.

Internationals arrive in the Netherlands in a specific kind of bind. They usually earn too much for social housing but don't have the documentation or financial history to get a mortgage. They need the mid-market rental segment — the one that opkoopbescherming is hollowing out.

The homes most likely to be illegal to let under the WOZ cap are precisely those that internationals can afford. A €350,000 apartment in Amsterdam Noord? Probably under the cap. A €450,000 place in Bos en Lommer? Same. These are the price points where small landlords used to operate, and where internationals used to find housing.

Now those landlords are selling. The buyers are owner-occupants. And the international renter who would have lived there is competing with 450 applicants for a social unit they probably don't qualify for, or staring at a €2,200/month listing on the liberalised market.

Some end up in precarious sublets, sometimes illegal ones, because the legal options have narrowed to almost nothing. That's not a housing strategy. That's a crisis management plan.

There's a quieter danger that most internationals never hear about until it's too late. If you rent a property that was recently purchased and falls under the opkoopbescherming WOZ cap, your lease may be illegal — even if you found it on a legitimate platform, even if the landlord seemed above board.

Municipalities monitor compliance using registration and utility data. Violations can result in fines, forced sales, or lease termination. Which means a tenant who signed in good faith can face eviction through no fault of their own.

I've talked to renters who had no idea their apartment was subject to opkoopbescherming. They found a listing, signed a contract, moved in, and months later got a letter from the gemeente. The complexity of the rule — WOZ thresholds, four-year occupancy requirements, narrow exceptions — creates a legal grey zone that punishes the people least equipped to navigate it.

This is the part that feels most unfair. The policy was designed to protect ordinary people. Instead, it's created a trap for the exact demographic it claims to serve.

The European Commission, the IMF, and the OECD have all cautioned the Dutch government that its cumulative regulations — opkoopbescherming, the Affordable Rent Act (Wet betaalbare huur), higher transfer taxes, stricter energy requirements — are undermining the private rental market.

The IMF specifically notes that while most low-income tenants have access to social housing, those who don't qualify and can't buy are left with almost nothing. The OECD highlights that low- and middle-income households, especially singles, are being squeezed out of both the ownership and rental markets simultaneously.

The Dutch government is now considering easing some rent controls to stem the investor exodus. But the damage to the mid-market is already significant. You don't unwind the loss of 5,000 Amsterdam rental homes by tweaking a points system.

The deeper issue is structural. Over 38% of Dutch households live in rental housing, but only 4.1% sit in the mid-rental segment, with another 4.1% in the liberalised sector. The vast majority of rentals are either tightly regulated social housing or expensive private lets. There's almost nothing in the middle. And opkoopbescherming is making that worse, not better.

I'm not arguing that opkoopbescherming should be scrapped entirely. The instinct to protect first-time buyers from speculative investors isn't wrong. But a blunt instrument applied across 60% of Amsterdam's housing stock is creating damage that outweighs the benefit.

The rule needs nuance. Properties that have historically been rentals should be eligible for continued rental use, even under the cap. Exceptions should exist for homes that serve international workers — the people Dutch employers actively recruit and then can't house. And municipalities need to provide clear, accessible information on which properties can legally be rented, so tenants aren't signing leases that could collapse under them.

More fundamentally, the Netherlands needs to build. Tax breaks, streamlined permitting, public-private partnerships — whatever it takes to expand mid-market rental supply. Restricting the existing stock through layered regulation is a zero-sum game. Every home that moves from rental to owner-occupancy is a home taken from someone who can't buy.

Amsterdam markets itself as a global hub for talent and innovation. That pitch rings hollow when the people you're recruiting can't find a place to live.
