How a Foreigner Can Buy an Apartment in Poland: Part 3 — The Search, the Purchase, and Life After Closing
The last of three parts. Part 1 covered the rules and costs; Part 2 covered the money. This is the part you actually came for: finding a flat and buying it.
You've worked out whether you can buy and how you'll pay. Now comes the fun bit — and the bit where a clear head saves you the most money. Here's how the search and the purchase really go, from first listing to the keys in your hand. As before, treat this as a practical map rather than legal advice; your notary and lawyer fill in the specifics of your deal.
Finding the flat
Most listings live on a handful of big Polish portals, and the same flat often appears under several agents at slightly different prices. The descriptions are in Polish, but a few words do most of the work. Rynek wtórny means resale; rynek pierwotny means a new-build from a developer (which, remember from Part 1, changes the tax). Powierzchnia is the floor area in m². Stan is the condition — do remontu means it needs gutting, deweloperski means bare walls and no flooring, wysoki standard means done up. Piętro is the floor, and you'll want to know if there's a winda (lift). And rok budowy, the year it was built, tells you a lot: a pre-war tenement, a communist-era block, and a new build behave very differently on upkeep and resale.
The single most useful habit is to sanity-check a price against the local average before you get attached. Our city price pages show what each market is really doing, and because we track actual notarial transaction prices — what flats sold for, not just asking prices — you can see when a listing is hopeful rather than realistic. A price far above the area average needs a reason; far below usually hides one. If you're still weighing cities, the housing-market comparison and tools like Warsaw vs Kraków or the rent-vs-buy calculator help you decide where your money actually goes furthest.
Don't over-trust the photos. The same price buys wildly different things across districts, so if you don't know the city, lean on transport links, the monthly building fee, and the year of construction rather than the staging.
Agents, and viewing from abroad
An agent (pośrednik) in Poland might be working for the seller, for you, or — in practice — for both. The seller's agent is not on your side, so if the search is complex or you're overseas, consider hiring your own buyer's agent and agreeing their fee (usually 1–3%) in writing up front.
If you can't fly in for viewings, ask for a live video walkthrough rather than a photo set, and have the agent show you the windows, the water pressure, any damp, and the state of the stairwell and entrance — a well-run building shows in its common areas. And if you can't attend the signing either, set up a power of attorney early: as noted in Part 1, it has to be notarised and usually apostilled abroad, which takes time you won't have at the last minute.
Before you commit: do your homework
Never buy on trust. Before you put money down, you or your lawyer should pull a current extract from the Land and Mortgage Registry (Księga Wieczysta) and check three things in particular: who legally owns the flat, whether it's full ownership or a cooperative right, and — crucially — whether there's a mortgage or other claim registered against it. A seller's existing mortgage has to be cleared out of the sale money, and the notary structures that; you just need to know it's there.
Ask for proof there are no arrears on the building fee or utilities, since unpaid balances can quietly become yours. For a new-build, confirm the flat has its own registry number (not just the building's), that the developer is properly registered, and that your payments sit in a protected escrow account. And if you're a non-EU buyer, get the notary to confirm — again — whether your specific purchase needs the ministry permit. A city flat is almost always exempt; a house with land usually isn't.
The preliminary agreement
Once you and the seller shake hands on a price, you sign a preliminary agreement (umowa przedwstępna). This is the backbone of a Polish purchase and it protects both of you. It names the parties, the flat, and the price; sets the deadline for the final deed; and records the deposit, usually 5–10%.
Two details are worth real attention. First, the type of deposit: a zadatek has teeth — if you walk away you lose it, and if the seller walks away they owe you double — whereas a plain zaliczka is just a refundable advance. Second, the conditions. If you're borrowing, make the agreement conditional on your mortgage being approved (see Part 2) so you don't lose the deposit if the loan falls through. If you need a permit, make it conditional on that. You can sign this as a private contract or as a notarial deed — the notarial version costs more but lets you force the sale through the courts if the seller gets cold feet, which is worth it on a big purchase.
Closing day: the notarial deed
The sale is completed by a notarial deed (akt notarialny) signed in front of the notary — who, remember, is neutral, not your advocate. On the day, the notary checks everyone's identity and a fresh registry extract, and confirms whether a permit applies. If you don't speak Polish, a sworn translator must be there to read the deed to you in a language you understand, so book that ahead. The deed is read aloud and signed, the balance is transferred (often through the notary or an escrow arrangement — and if you have a mortgage, the bank releases the funds straight to the seller), and the notary collects the taxes and fees from Part 1 and forwards them. The moment you both sign, you legally own the flat — even before the paperwork catches up.
After signing
The notary files the transfer with the registry. Two entries matter: your ownership, which becomes legally effective from the deed even though the court entry takes a few weeks to finalise, and, if you borrowed, the bank's mortgage. Until the mortgage entry appears, the bank often charges a slightly higher bridging rate, which drops off once it's registered. Keep your stamped copy of the deed somewhere safe — it's your core proof of ownership and you'll need it for utilities, insurance, and any future sale.
In the first days, take meter readings on handover and note them in writing with the seller so you're not billed for their usage. Move the utility contracts and the building fee into your name, and tell the building management you're the new owner. Sort out buildings insurance — if you have a mortgage the bank requires it and must be named (see Part 2). And keep your tax number handy for the small annual property tax. From here on it's the running costs from Part 2 — the building fee, utilities, insurance, and that modest tax — and not much else.
The whole journey, in one breath
Across the three parts, the path looks like this: in Part 1 you sorted the rules, the budget, the bank account, the tax number, and a notary. In Part 2 you decided between cash and a mortgage and lined up the money. And here in Part 3 you searched, did your due diligence, signed a conditional preliminary agreement, completed the deed, registered the title, and took the keys. That's the full arc — from "can I even buy here?" to standing in your own flat in Poland.
