Sleutelgeld in the Netherlands: why any reservation fee before move-in is a red flag

Someone writes in, usually a student heading to Amsterdam, Utrecht, or Groningen, and the message goes something like this: 'The landlord asked me to transfer €500 to reserve the room before viewing. Is that normal here?'

Short answer: no. Not normal. Not legal in most framings. And in the cases where it technically could be legal, it's almost never worth paying.

I run House Hunter, so I see the underbelly of the Dutch rental market every day — the fake Pararius clones, the 'I'm currently in Ireland, here's the IBAN' landlords, the Kamernet profiles built in twenty minutes. The single most consistent entry point into all of these scams is the pre-move-in payment, dressed up as sleutelgeld, a reservation fee, an administratiekost, or a 'booking confirmation'.

The label keeps changing. The pattern doesn't.

Sleutelgeld literally means 'key money' — a payment demanded just for handing over the keys or for 'holding' a property. Dutch law is blunt about it: you cannot charge a tenant for access to a home on top of the deposit and first month's rent. It's illegal. It has been for a long time, and it's reaffirmed by every tenant advocacy body I've ever pointed a user toward, from!WOON to the Huurcommissie.

The trick is that landlords and shady intermediaries rarely call it sleutelgeld anymore. They call it a reservation fee, an admin fee, a contract-drafting fee, a screening fee. The Rechtswinkel's position — and the one Dutch courts tend to follow — is that any such fee has to be proportionate and tied to an actual, demonstrable cost. A blanket €250 or €500 to 'hold the room' is not that. It's sleutelgeld in a suit.

There's also a separate rule worth knowing: if an agency is working on behalf of the landlord (so you didn't hire them — the owner did), they can't charge you bemiddelingskosten either. That one was settled years ago and landlords' agents still try it, especially in Rotterdam and Den Haag.

So when you hear 'just transfer €300 and the room is yours,' you're not looking at a Dutch custom. You're looking at someone testing whether you know the rules.

The Dutch housing crisis creates the perfect conditions for this. Student housing waiting lists in cities like Utrecht and Groningen stretch past two years. Private rents sit 20–40% above regulated student housing. If you're landing at Schiphol in three weeks with a signed master's offer, you are, by definition, desperate.

Scammers know this. The numbers from 2024 are brutal: Dutch residents lost an estimated €1.75 billion to housing fraud, with individual victims typically out between €2,000 and €5,000. Only around 1% ever get their money back. Expats and international students are disproportionately represented in those losses because they can't view in person, they're paying from foreign accounts, and they're often working in their third language on a Dutch-language contract.

I've watched users lose a month's rent plus deposit to a 'landlord' who owned exactly zero properties. The common thread is never the city or the platform. It's always the same moment: a payment requested before viewing, before BSN registration was confirmed, before a real contract was on the table.

Here's where it gets slippery, because not every upfront cost is a scam. Some are legitimately grey.

A real example: a landlord in Delft asks for a €50 credit-check fee through a named screening company, with a receipt. That can be defensible under Dutch law if the cost is real, proportionate, and not refundable only because you backed out. The Rechtswinkel's framing is that the burden of proof is on the landlord — they have to show the cost exists and is reasonable.

Contrast that with a 'reservation fee' of €400 that 'will be deducted from your first month's rent' if you sign. That's the one internationals get hit with most often. It sounds reasonable. It is not. There is no legal mechanism in the Netherlands that lets a landlord charge you to take a listing off the market before a contract exists. If you don't sign — for any reason, including them changing the terms — that money is almost never coming back, and the huurcommissie route is long, uncertain, and depends on you being able to prove who you paid.

My rule of thumb, and I tell every House Hunter user this: if the 'fee' is more than €50–75, or if it's demanded before you've physically seen the property and met the person renting it out, treat it as sleutelgeld. Refuse. If it's a real landlord, they'll find a way to work with you. If they walk, you just dodged something worse.

For contrast, here's what the payment flow should look like when things are clean.

You view the property, either yourself or through someone you trust. You see ID from the landlord or check them on KVK.nl if it's a company. You get a written contract — in Dutch, with an English translation if you ask, which you should. The contract names the landlord, the address, the rent, the service costs (servicekosten) broken out, the deposit, and your right to register at the address with the municipality (the BRP inschrijving — non-negotiable; if they say no, walk).

You then pay: first month's rent, plus a deposit capped at a maximum of two months' rent for regulated tenancies. That's it. No 'reservation', no 'key handover fee', no 'admin' on top. If the agency is working for the landlord, no bemiddelingskosten from you either.

In the free sector, rent can rise — capped at 4.4% per year in 2026 — and you can run the starting rent through the huurprijscheck on the Huurcommissie website to see whether it's even in the regulated bracket. A lot of rooms in Eindhoven and Rotterdam that get marketed as 'free sector' actually fall under the points system (WOZ-based) and are being overcharged on day one. That's a separate fight, but it's worth knowing before you sign.

Nothing in that legitimate process involves a Tikkie or IBAN transfer to hold a room sight unseen.

The objection I get from users is always: 'But if I refuse, I lose the room, and the market is insane.' Fair. So here's what actually works, based on messages I've seen go back and forth in real negotiations.

Ask in writing — email, WhatsApp, anything with a timestamp — for the fee to be itemised. 'Could you specify what this €300 covers and provide a receipt?' Legitimate landlords will either drop the fee or produce a real screening-company invoice. Scammers disappear or get aggressive. Both outcomes are useful.

Mention the Huurcommissie by name. Not as a threat, just as context. 'I understand the Huurcommissie considers blanket reservation fees unlawful, so I'd like to structure this as a deposit against the signed contract instead.' Nine times out of ten, a real landlord just says fine. A fake one ghosts.

Offer to sign the contract first, then pay. This is the cleanest test. If they refuse to send a contract until money moves, that's your answer. No legitimate Dutch landlord needs your €500 before paperwork exists.

And stick to platforms with actual verification. Funda, Pararius, Kamernet, and university housing portals aren't perfect, but the scam rate is dramatically lower than on Facebook groups or Marktplaats. House Hunter pulls from 1,000+ sources, and the ones where we see the most sleutelgeld patterns are consistently the informal ones — social media groups, WhatsApp chains, unverified listings forwarded friend-to-friend.

Every time a Dutch landlord asks for money before you've seen the place and signed a contract, one of two things is true: they're breaking the law, or they're not a landlord.

There isn't really a third option. The Dutch rental system, for all its flaws and for all the pressure of the current market, does not require tenants to pay to be considered. The deposit plus first month's rent is the entire legitimate upfront cost. Anything else needs a receipt and a real justification, and most of the time it won't hold up.

You have more leverage than the urgency makes you feel. The market is brutal, but it's not so brutal that you need to wire €400 to a stranger named 'Mr. Johnson' whose property is, conveniently, already locked and whose keys are, conveniently, with a courier. Slow down for ten minutes. Ask for the itemisation. Ask for the contract. Check the KVK. If the listing evaporates because of those questions, it was never yours to begin with.
