Many people think that mortgage in Poland Depends solely on your salary. In practice, banks analyze many more factors: loans, card limits, credit history, type of employment, expenses, regularity of income, and even how you use your bank account.

People often lose hundreds of thousands of zlotys in creditworthiness due to small issues that could have been addressed in advance. Someone forgot to close a credit card, someone took out an installment plan for a phone, and still others regularly run into the red on their account. For a bank, these are all risk signals.

The good news is that you can prepare for a mortgage in advance. Starting at least six months before applying can significantly increase your chances of approval and get better terms.

In this article, we'll take a detailed look at how to properly prepare for a mortgage in Poland in 2026 so that the bank sees you as a reliable client.

Why is mortgage preparation so important?

The bank evaluates not only your current situation, but also your financial behavior over the past months.

The following are analyzed:

• receipts to the account;
• regularity of income;
• expenses;
• credit history;
• active loans;
• limits;
• debts;
• stability of work;
• industry;
• family situation.

Even a person with a good salary can be rejected due to poor preparation.

1. Close all credit cards

This is one of the most important points.

Many people think:
«"I don't use a credit card, so there's no problem.".

There is a problem for the bank.

Even if on a credit card:

• 0 zł in debt,
• you don't use it,

the bank still takes the limit itself into account as a potential debt.

Example

You have:

• credit card for 20,000 zł;
• installment card for 10,000 zł;
• account limit of 15,000 zł.

This is already a serious burden for the bank.

Some banks reduce creditworthiness by:

• 150–300 zł monthly for each limit;
• sometimes even more.

As a result, you can lose:

• 50,000–150,000 zł mortgage capacity.

2. Close limits on bank accounts

Many people forget about:

• debit;
• limit odnawialny;
• limit in ROR.

Even if you've never used it, the bank still sees it.

Before taking out a mortgage, it is better to:

• close the limit completely;
• receive confirmation of closure;
• wait for the data in the BIK to be updated.

3. Pay off all installments (raty)

Telephones, equipment, furniture, household appliances - all of this reduces creditworthiness.

Even:

• iPhone in installments;
• TV;
• laptop;
• 0% raty —

affect the mortgage.

For the bank, this is a full-fledged loan.

Sometimes installments for:

• 150–300 zł per month

can reduce your mortgage by:

• 20,000–50,000 zł.

4. Try to pay off consumer loans

If there is:

• gotówkowy;
• bag;
• chwilówki;
• car loan,

This has a very strong impact on mortgages.

Banks have a particularly negative view of:

• microloans;
• frequent loans;
• refinancing;
• payment delays.

5. Don't take out new loans for at least 6 months

This is a huge mistake before a mortgage.

It is forbidden:

• take the phone;
• buy equipment in raty;
• apply for credit cards;
• use BNPL;
• take out quick loans.

Even a simple BIK check can temporarily reduce your scoring.

6. Raising your salary before a mortgage really works

This is one of the most underrated ways to build credit.

If possible:

• increase the official salary;
• increase the fixed portion of income;
• show additional regular payments,

This can greatly influence the bank's decision.

Sometimes salary increases by:

• 1000–2000 zł netto

increases mortgage capacity by:

• 80,000–200,000 zł.

Especially important:

• so that the income is official;
• was credited to the account;
• was regular.

After receiving a mortgage, many people return to their previous income level or tax burden—banks no longer recalculate creditworthiness after issuing a loan.

7. Don't change jobs before a mortgage

This is one of the most common mistakes.

The bank loves:

• stability;
• long-term experience;
• continuity of work.

If you:

• changed employer;
• went on probation;
• opened a new JDG,

the bank can:

• reduce creditworthiness;
• request additional documents;
• refuse.

Perfect:

• at least 6-12 months of stable work.

8. Monitor your BIK history

BIK is a Polish credit history.

Banks see:

• delays;
• active loans;
• limits;
• applications;
• number of requests.

Even overdue:

• 1–3 days

may sometimes worsen scoring.

What is particularly bad for BIK?

• frequent loan applications;
• chwilówki;
• delays;
• a large number of credit cards;
• high percentage of limit usage.

9. Avoid gambling and suspicious transfers

Banks analyze account statements.

They look very bad:

• casino;
• bookmaker bets;
• crypto exchanges;
• frequent transfers to unknown persons;
• suspicious cash receipts.

Some banks directly ask questions about such transactions.

10. Increase your down payment

The greater the own contribution:

• the higher the chance of getting a mortgage;
• better conditions;
• lower interest rate.

Minimum:

• usually 10–20%.

But when:

• 20–30% wkład własny

The bank looks at the client much better.

11. Don't allow your account to go into negative balance.

If the bank sees:

• regular minus;
• living paycheck to paycheck;
• constant use of the limit,

This worsens the customer's rating.

Better:

• leave a financial cushion;
• don't go to zero.

12. Entrepreneurs need to prepare in advance

For JDG, preparation is especially important.

Banks are watching:

• PIT;
• ZUS;
• KPIR;
• wraps;
• income;
• expenses;
• business stability.

What is important to an entrepreneur?

It's better not to underestimate your income before taking out a mortgage.

Many entrepreneurs:

• increase bones;
• reduce taxes;
• work at break-even.

This looks bad for the bank.

Sometimes it is more profitable:

• temporarily show higher income,
• pay a little more tax,
• but get a mortgage for a good amount.

13. Prepare documents in advance

Typically banks need:

• PIT;
• umowa o pracę;
• zaświadczenie o dochodach;
• account statements;
• ZUS;
• declarations;
• residence card;
• passport;
• BIK history.

If the documents are prepared in advance, the process goes much faster.

14. Don't make random transfers between accounts

Large quantity:

• transfers between your accounts;
• cash;
• unclear receipts,

may raise questions from the bank.

Especially among foreigners.

15. Try to receive your salary officially into your account

The bank does not take into account income "in an envelope".

The best looking ones are:

• official receipts;
• regular salary;
• equal amounts;
• stable employer.

16. For foreigners, residence status is important

Banks are more receptive to:

• karta stałego pobytu;
• resident of the UE;
• long-term stay.

But many banks also provide loans with:

• czasowy pobyt.

Main:

• stable income;
• good BIK;
• duration of stay in Poland.

17. Don't apply to 10 banks at once

Each application:

• leaves a trace in the BIK.

If the bank sees:

• 10-15 requests per week,

This looks like financial problems.

Better first:

• do an analysis;
• choose suitable banks;
• be served pointwise.

Why can a mortgage expert save you hundreds of thousands of zlotys?

Various banks:

• JDG is considered differently;
• B2B is considered differently;
• treat foreigners differently;
• use different algorithms.

Sometimes the difference between banks:

• 200,000–400,000 zł creditworthiness.

That's why proper preparation and choosing the right bank are key factors for success.
