Lately, many people on the forums have been house-hunting, and the most common topic is mortgages. It can feel quite complex, and banks’ requirements vary widely. Having just gone through this process myself, I’m here today to break down what banks really look for when you apply for a loan. I hope this helps others who are just starting out.
The Core of Bank Assessment: Stable Repayment Ability
To put it simply, what banks care about most is your ability to pay them back on time. They have an unwritten “golden rule”: your total monthly debt payments should not exceed 35% of your net income. Therefore, a stable job with a good salary is key. Having a permanent employment contract (contrato indefinido) is a huge plus. If you’re self-employed, the bank’s scrutiny will be stricter, and you’ll need to provide more documentation to prove your income stability.

Down Payment and Residency Status
Generally, banks will finance a maximum of 80% of the property’s value, meaning you need to come up with the remaining 20% as a down payment. But that’s not all; you’ll also need an additional 10% (approx.) of the property price on hand to cover various taxes and fees. Therefore, you should have at least 30% of the total property price in cash. For non-tax residents seeking a Spanish mortgage, many banks have stricter requirements and may only lend 60%-70%.
Besides money, your credit history is crucial. The bank will check your credit report to ensure you aren’t on any delinquency lists (like ASNEF). A history of unpaid debts will almost certainly disqualify you from getting a loan. Age is another implicit factor; banks calculate to ensure the loan will be fully repaid before you reach retirement age. The table below lists some essential documents you can prepare in advance.
| Document Type | Key Points |
| Identification | Valid NIE and residency card (TIE) |
| Proof of Income | Last 3-6 months of payslips, previous year’s income tax return (IRPF) |
| Employment Contract | A permanent contract is highly preferred, along with proof of length of service |
| Bank Statements | Last 6-12 months of bank statements to show your income and expenses |
| Credit Report | Some banks check this automatically; you can also request a CIRBE report from the Bank of Spain. This is a key document for any Spanish home mortgage. |
What banks value most is your stable and consistent ability to make repayments. The more complete your documentation and the healthier your financial situation, the better your chances of securing a favorable interest rate. Of course, each bank’s policies differ slightly—ING, Santander, and CaixaBank may have different priorities—so it’s advisable to shop around and compare offers.
