The three shapes
Spanish lenders offer non-residents the same three structures they offer anyone else.
- Variable. Your rate is 12-month Euribor plus a fixed margin — the diferencial. Euribor moves; your margin does not. The rate is recalculated every six or twelve months depending on the contract, and your monthly payment changes with it.
- Fixed. One rate for the whole term. The payment on the day you complete is the payment in year eighteen.
- Mixed. Fixed for an initial period — commonly three, five or ten years — then variable on Euribor plus a margin for the remainder.
How Euribor actually works
Euribor is the rate at which European banks lend to one another, published daily, and the 12-month figure is the reference for most Spanish variable mortgages. It is not set by your bank and your bank cannot influence it.
The thing worth understanding is the review mechanism. Your rate is not recalculated when Euribor moves. It is recalculated on your review date, using the published figure for the relevant month. So a change in Euribor reaches your payment with a lag of up to a year, and once it does, it stays until the next review. This cuts both ways: a rise does not hit you immediately, and a fall does not help you immediately either.
The margin is the part you and your broker can actually affect. It is set at the outset, it does not change for the life of the loan, and it varies between lenders and between applicant profiles. A better margin is worth more over twenty years than most people assume, and it is negotiable in a way Euribor is obviously not.
Why non-residents lean fixed
Spanish residents historically favoured variable rates, and plenty still do. Non-resident buyers tend to behave differently, for reasons that are about circumstance rather than forecasting.
If you live in the property, in the country, earning in the currency, a rising payment is unwelcome but visible and manageable. If the property is eight hundred miles away, the payment leaves an account you top up from another currency, and your Spanish income is zero, the same rise is harder to absorb and harder to notice coming. A fixed rate converts an unknown into a line in your budget.
There is a second reason. For a non-resident, a euro mortgage paid from sterling, krona or dollar income already carries currency risk. Taking a variable rate stacks a second unknown on top of the first, and the two can move against you at the same time. Fixing the rate removes one of them.
The honest position on which is cheaper: nobody knows. A fixed rate is priced with the lender's own view of the future built in, so you are not getting something for nothing — you are buying certainty, and the premium for it varies with where Euribor sits when you apply. Anyone who tells you confidently that one will beat the other over twenty years is guessing. The useful question is not which is cheaper but which you can live with if you are wrong.
Where mixed fits
A mixed rate suits a specific situation: you want certainty for the period you are most exposed, but you do not expect to hold the loan for its full term. Buyers who intend to sell within a decade, or who expect a lump sum — a pension drawdown, a business sale, the sale of a property at home — that will clear or substantially reduce the mortgage, get the protection where it matters and avoid paying for it where it does not.
It is a worse fit if you genuinely intend to hold for twenty-five years, because you are simply deferring the variable-rate decision rather than avoiding it.
What to compare beyond the headline rate
Two offers with the same rate can cost meaningfully different amounts.
- Early repayment charges. Spanish law caps these, and the caps differ between fixed and variable loans and by when in the term you repay. If there is any chance you will overpay, sell, or refinance, this matters more than a small difference in rate.
- Arrangement and opening fees, which vary and are sometimes negotiable.
- Bundled products. Most lenders offer a rate reduction for taking their home insurance, life cover, or for paying a salary or a certain amount into an account with them. Under Ley 5/2019 a lender cannot make the mortgage conditional on buying its other products, and where it offers a bundle it must also quote the mortgage standalone so you can compare. Sometimes the bundle genuinely is cheaper overall; sometimes the discount is smaller than the premium.
- The review frequency on a variable or mixed loan — six-monthly reviews pass rate changes through twice as fast as annual ones, in both directions.
How to decide
Work out what your payment would be on the fixed offer, and what it would be on the variable offer if Euribor rose substantially from where it is. If the second number is uncomfortable, fix, and treat the premium as the cost of sleeping properly. If it is absorbable, the variable offer is a legitimate choice and may well prove cheaper.
That is a calculation about your finances, not about rate forecasting, which is the point. We run it across the actual offers rather than working from a rule of thumb, because the gap between fixed and variable pricing is different every month and between lenders.
