Spanish mortgages step by step: what the bank asks for, and when to apply

The order matters more than the bank. If you apply for the mortgage once the deposit contract is signed, you are racing the clock — and that always costs, whether in the rate, the terms or your nerves. Here is what to settle before you make an offer.

1. Before viewing homes: know what they will lend you

Spanish banks normally lend up to 80 % of the valuation or the purchase price, whichever is lower. The remaining 20 % plus the purchase costs — between 10 and 12 % in Catalonia, counting transfer tax or VAT, notary, land registry and paperwork — come out of your pocket. On a €600,000 home that is around €190,000 in cash. Knowing it before you fall in love with a house saves you the worst kind of disappointment.

The other rule is the instalment: most lenders do not want your total monthly debt to exceed 35 % of your net income. Those two numbers give you your real ceiling, and it is the one I use to filter what I show you.

2. The paperwork you will need

It is always the same list, and having it scanned in advance saves weeks:

01ID or NIE for every buyer. 02Your last three payslips and your employment contract. If self-employed, your tax return, quarterly filings and social security record. 03Income tax returns for the last two years. 04Six months of bank statements and proof of your savings. 05A statement of your outstanding debts: car, loans, deferred card balances.

3. The right moment to apply

Get pre-approval before you make offers. It is free, commits you to nothing and lasts three to six months. With it in hand you negotiate differently: the seller knows you can sign, and that is sometimes worth more than raising your price.

Once the deposit contract is signed, the clock starts: valuation, risk assessment and binding offer usually take four to eight weeks. That is why the deposit contract should set a realistic deadline and, where possible, a condition tied to the financing.

Never sign a deposit contract with a 30-day deadline if the mortgage is not pre-approved. Losing your deposit to a calendar is the most expensive mistake I see.

4. Fixed, variable or mixed

There is no single right answer. Fixed buys peace of mind and suits you if you will stay many years; variable can work out cheaper over a short term or if you plan to repay early; mixed is the middle ground most people sign lately. What does deserve a magnifying glass is the tie-ins: life and home insurance, salary account, cards. A pretty rate with three products attached costs more than an average clean one.

5. If you are buying from outside Spain

For non-residents, lending usually drops to 60 or 70 %, and the bank will want your income documents translated and sometimes apostilled. You will need an NIE and a Spanish bank account; both can be arranged by power of attorney without living here. It is slower, not harder: allow an extra month.

If you like, we can go through your numbers before you start viewing homes. I work with a mortgage broker who compares several lenders at once, and in half an hour you will know your real ceiling and which documents you are missing.
