Preparing for a mortgage is a process where small financial slips in the last 3–12 months can lead to a refusal or a lower loan amount. Here are the most common mistakes — and how to avoid them.1. Making big changes right before you applyChanging jobs, switching your contract type (for example, from an employment contract to your own business, JDG) or starting a new business just before applying can work against you. Banks usually expect a minimum time in your current situation: often 3–6 months for employees and at least 12 months for business owners.2. Keeping unused credit cards and limitsCredit cards (even with a zero balance), overdraft limits and active instalment plans — including popular Polish "buy now, pay later" services like PayPo or Allegro Pay — all count. For the bank, an available limit is potential debt, and it reduces how much you can borrow.3. Late payments — even small onesPaying instalments, utility bills, fines or small loans late — even by a few days — can be recorded in BIK, the Polish credit bureau, and lower your credit score.4. Applying to every bank at onceEvery official application creates an inquiry in BIK. Applying to 5–7 banks at the same time can look like high risk to the system and reduce your chances of approval. It's better to choose the right banks first.5. Hiding expenses or commitmentsTrying to leave out children, alimony or existing loans doesn't work. Polish banks carefully check your bank statements, usually for the last 3–6 months.6. Applying with a residence card that expires soonFor foreigners, the validity of your residence card matters. If it expires soon, some banks may refuse or ask you to wait for a new one. Check this before you apply.
