In Polish: Promesa kredytowa
This is the word you will see in bank documents.
Definition
A loan promise (promesa kredytowa) is the bank's written undertaking to grant a loan up to a specified amount if you meet stated conditions within a set time. The bank issues it after assessing your creditworthiness, often before the specific property is known or before all its documents are ready. The Polish Mortgage Credit Act also covers an agreement in which the lender promises to grant a loan, but the rules for issuing promises depend on the bank.
What it means for you
A promise shows the seller, or a bailiff running an auction, that you have financing, so it strengthens your position. It does not guarantee the payout, though: the bank will still assess the property and check that your situation has not changed. Some banks charge a fee for a promise, and its validity is limited.

Frequently asked questions
Does a loan promise guarantee the loan?
No. It is a conditional undertaking. The bank pays out the loan once the conditions in the promise are met, including a positive property valuation and no deterioration in your situation.
How much does a loan promise cost?
It depends on the bank. Some banks issue it free, others charge a fee according to their price list.
Do I need a loan promise to buy a flat?
For an ordinary purchase usually not. It is useful at a bailiff's auction, in some programmes and in negotiations with the seller.
