Mortgage pre-approval for expats in Prague: what it is and how to get one

You find a flat on Friday. The seller wants a reservation by Monday. You have no idea whether a Czech bank would lend you the money. A pre-approval keeps you out of that spot: you search with a number a lender has at least looked at.

This guide explains the idea and what expats should prepare. It is not mortgage advice, and every lender decides for itself.

What a pre-approval is

It goes by several names: pre-approval, pre-assessment, indicative offer. In every case a bank, or a broker working with several banks, looks at your income, costs, debts and documents and tells you roughly how much it could lend and on what terms. It is not a binding offer. The final decision comes after the bank values the property and checks the legal documents.

So treat it as a planning tool. It helps you set a budget, shows what documents are missing and tells you whether a particular lender will consider your situation at all.

What banks look at

Czech lenders weigh your income and its stability, existing debts, regular costs, deposit and the property. They check credit registers. For expats the extra questions are usually these:

• Residence status. Which permit you hold, how long it is valid, and whether you have lived in Czechia long enough for the bank's rules.
• Income history. How long you have worked for your employer, the type of contract and whether the income is in Czech koruna or abroad.
• Documents. Passport, residence permit, employment contract, income confirmations, tax filings and bank statements. Translations may be required.

Banks differ. Some lend to non-EU nationals on a long-term permit, some ask for more equity or a longer record, and some do not lend at all. Our guide to mortgages for expats lists the checks, and the page on mortgages for foreigners on Hypoteky.com goes through the options.

The deposit and the limits

The Czech National Bank recommends a maximum loan-to-value (LTV) of 80% for owner-occupied housing, and 90% for applicants under 36 (as of 2026; check the Czech National Bank). For investment properties, the recommendation is stricter from 1 April 2026 (check cnb.cz for the definitions). Banks apply the recommendation in their own way, so ask how the under-36 rule applies to your application. Our guide to how much deposit you need explains how the deposit works, and the 30-year loan guide shows how repayments behave.

For a first look at the borrowing side, the borrowing estimator on Hypoteky.com shows what a bank may lend based on income and costs. It is an estimate and not advice.

Validity and small print

A pre-approval has a shelf life. Ask how long it holds, what could change it (a job change, a new debt, a rate move) and whether asking costs anything. Some brokers charge nothing to the borrower and are paid by the lender; others charge. Ask how a broker is paid, and which lenders they cover, before you hand over documents. A broker may not cover every bank.

Rates and fees change often, and the offer you see may not be the one you sign. Our guide to comparing mortgage offers shows what to compare, and the one on buying with a partner covers joint applications.

After the pre-approval

Once you have a number, shop. Our viewing checklist and the guide to buying your first flat walk through the next steps. If a lender or intermediary treats you unfairly, the Financial Arbiter handles some disputes; check its website for what it covers.

Where expats get stuck

Four situations are worth raising with the lender early.

Short time in the job or the country. Banks like a track record. If you changed employers recently, ask whether the lender wants you past a probation period, and whether a contract of a particular type or length matters.

Income paid abroad or in another currency. Lenders can treat foreign income differently, ask for extra proof or lend less against it. If you are paid in euros or dollars, say so in the first call.

Self-employed or contractor income. You will usually be asked for tax returns covering more than one year, and the lender decides how much of the income it counts. Our guide to filing a Czech tax return explains the paperwork behind those returns.

A residence permit that is about to expire. A lender wants to see that you can stay for the life of the loan, or at least for a long time. Ask how it treats a permit with a short validity, and whether an extension in progress counts.

If the answer is no

A refusal from one bank is not the market's verdict. Lenders weigh the same facts differently, so ask what the reason was, whether a larger deposit, a co-borrower or a longer record would change it, and which products suit your case. Brokers can show you which banks are more open to foreign borrowers, but check how they are paid.

You can also wait and build the record. A year more in the job, a fuller tax history or a bigger deposit moves the answer more than shopping the same file to every bank. In the meantime, our guide to renting in Prague with no Czech and the one on apartments to rent keep you housed while you do it.
