Mortgage in Poland for foreigners: KNF rules, rates, documents
Short answer: Banks assess foreigners case by case. KNF's Recommendation S points to income in zloty and a down payment, and a market guide says a residence card is key. The NBP rate was 3.75% on 7 October 2026.
Can a foreigner get a mortgage in Poland? Banks decide case by case. What shapes their answer is a mix of the financial supervisor's rules, the bank's own policy and your documents. This guide explains the parts that are written down in official sources, separates them from market practice, and shows where interest rates stand. Information is as of 16 October 2026. It is general information, not financial advice, and each bank sets its own conditions.
What the supervisor requires of banks
The Polish Financial Supervision Authority (KNF) publishes Recommendation S, a set of good practices for banks that grant mortgage-secured loans. Banks follow it when they assess every applicant, Polish or foreign. Points from the version amended in June 2023 and earlier texts:
- Income currency. A bank should grant mortgage loans to retail clients in the currency in which they earn their income (Recommendation 6). If a household earns in several currencies, the bank assumes that currencies other than the main income currency lose 50% of their value when it calculates your ability to repay.
- Own contribution. A bank should not finance the full value of the property and should require a down payment from the borrower (Recommendation 10). Funds from government housing support programmes can count towards it.
- Credit history. When assessing creditworthiness, a bank should always use external databases, including the interbank databases (Recommendation 11).
The practical result for a newcomer is simple. Salary paid in zloty is the strongest basis for a loan in zloty. Income received in euros or dollars is treated with a haircut, and a loan in a foreign currency is something banks offer only in narrow cases.

What banks usually ask of foreigners
The KNF recommendation does not list documents for foreigners. The following comes from a commercial guide published by KrakowInvest in June 2026, so treat it as a market overview and confirm it with the bank:
- A residence card (temporary or permanent) is described as the key document, and without it banks may ask for a larger down payment, guarantors or refuse.
- Income in zloty, best under an employment contract, is the basic condition for most offers.
- A PESEL number is useful for identification and tax purposes.
- A credit history in BIK helps. A missing history does not mean automatic refusal, but it makes the assessment harder.
- The same guide gives a standard down payment of 20%, or 10% with insurance of the low down payment, and says that several large banks lend to foreigners, including PKO BP, Pekao, mBank, Santander, ING, Millennium, Alior and BNP Paribas.
These points come from one source and can change from bank to bank. Ask at least two or three banks, or an independent broker, what they require for your residence status before you sign a reservation agreement for a flat.
Interest rates: where things stand
The National Bank of Poland (NBP) reference rate is 3.75%. According to GazetaPrawna, reporting the NBP announcement of 7 October 2026, the Monetary Policy Council kept it unchanged, with the deposit rate at 3.25% and the Lombard rate at 4.25%. Finwire notes that the reference rate has stood at 3.75% since 5 March 2026, and that the flash estimate of inflation for September was 4.0% year on year. ING's economists write that the Council may discuss tightening after the November projection, and their baseline forecast is two 25-basis-point increases in the first quarter of 2027. This is a forecast, not a decision.
A mortgage rate is set by the bank and depends on the bank's margin, the reference rate used in the contract and the offer. The NBP rate is a signal of direction, not the rate you will pay. Check the rate, margin, fees and insurance in the bank's written offer.
Steps to take before you apply
- Collect your documents: identity document, residence card or EU registration, employment contract and recent payslips or bank statements.
- Check your credit history before you apply, since banks will look at it.
- Compare total cost, not only the headline rate. Ask about the margin, commission, insurance and early repayment terms.
- Plan for a rate change. If rates rise, a variable-rate instalment rises too.
- Budget for the purchase costs. Our guides on notary fees and on the PCC tax explain the main ones.
Frequently asked questions
Can a non-EU citizen get a mortgage in Poland?
Banks decide individually. According to a market guide from June 2026, a residence card and income in zloty are the key conditions, and without a card banks may ask for a larger down payment or refuse.
Why do banks prefer income in zloty?
KNF's Recommendation S says banks should lend in the currency of the client's income, and for households with several currencies the bank should assume a 50% loss of value for the other currencies when assessing repayment ability.
What is the NBP reference rate now?
3.75%, unchanged at the Monetary Policy Council meeting that ended on 7 October 2026, according to GazetaPrawna.
Do I have to put down my own money?
KNF's recommendation says banks should require a down payment. The size depends on the bank and the loan. The guide cited above gives 20% as standard and 10% with insurance.
