First-time buyer mortgage in Spain 2026: a complete guide to applying

Applying for your first mortgage can seem an intimidating process if you don't know how it works. There's a lot of contradictory information, a lot of banks that seem to tell you what you want to hear and a lot of hidden costs that turn up late. This guide explains it all without beating about the bush, with real 2026 data.

Types of mortgage available

Variable-rate mortgage: The interest rate is Euribor plus a fixed margin (e.g. Euribor + 0.6%). When Euribor goes up, the repayment goes up; when it goes down, the repayment goes down. In October 2026, with Euribor at 3.239%, the resulting rate is 3.839%. Historically it's the most common type in Spain.

Fixed-rate mortgage: The rate doesn't change over the whole life of the loan. In 2026, fixed rates are around 3.2-3.8% depending on the term and the bank. The repayment is predictable, which makes planning easier. Recommended if you want absolute certainty.

Mixed-rate mortgage: Fixed for the first 5-15 years, then variable. It offers initial stability with the chance to benefit from future falls in Euribor. In 2026 it's proving a popular option.

How much you can borrow: the bank's criteria

The bank lends 80% of the lower of the purchase price and the appraised value (for a main home). The monthly repayment can't exceed 35-40% of your net monthly income. A concrete example: if you earn €2,000 net a month, the bank will lend for a maximum repayment of €700-800 a month. At a rate of 3.5% over 30 years, that's equivalent to a mortgage of around €155,000-175,000.

The paperwork they'll ask for

• DNI or NIE (the Spanish national ID card, or the foreigner's identity number)
• Your last 3 payslips, or 2 years of modelo 390/100 (the annual VAT summary and the income tax return filed with the AEAT, the Spanish tax agency) if you're self-employed (autónomo)
• Your last income tax return (IRPF, Spanish personal income tax)
• An up-to-date vida laboral (your Social Security employment history report)
• Bank statements for the last 3-6 months
• If you have other debts (loans, leases): the paperwork for them

How to get the best terms

Don't just go to the bank you've always used. Ask at least 3-4 lenders for offers and use a mortgage broker if you find the process complicated. Brokers have access to terms that aren't available through the branch network, and their service is usually free (the bank pays them for handling the application). In 2026, the difference between the worst and the best offer on the market can be 0.5-1 percentage point of interest: on a €150,000 mortgage over 30 years, that means tens of thousands of euros of difference.
