The mixed-rate mortgage — and what happens when the fixed period ends
Spain offers three structures: fixed (fija), variable (variable) and mixed (mixta). The mixed one is now the most frequently chosen — and the least understood, because the decisive part only starts once the fixed period runs out.
In short
What happens when the fixed period ends?
No renegotiated follow-up as in Germany — the existing contract carries on, tied to the Euríbor from that point instead of fixed.
Can I switch lender afterwards?
Yes, via subrogación — comparatively straightforward in Spain. It takes time and assumes you are still financeable, at a greater age than when you first signed.
Are bonificaciones worth it?
The rate benefit of product tie-ins is real, but it must be weighed against the running cost of the products (insurance, salary account, cards).
What is a mixed mortgage (hipoteca mixta) in Spain — and what happens after the fixed phase?
Spain offers three rate structures: fixed (fija), variable (variable) and mixed (mixta). The mixed one combines both: a fixed rate for the first years, after which the loan automatically switches to a variable rate — usually the Euríbor plus a fixed bank margin. It is this second part that is often overlooked. The end of the fixed phase is not a date to tick off but a new instalment: if the Euríbor has risen by then, your monthly payment rises without you signing anything. For non-residents the choice of banks and the terms are tighter anyway — the margin over the Euríbor tends to be higher here. Before choosing a mixta you should therefore know two things: the length of the fixed phase and the agreed Euríbor margin afterwards. We compare the structures across several banks so the chosen one fits your term and your risk appetite.
The three structures
| Fija (fixed) | Variable | Mixta (mixed) | |
|---|---|---|---|
| Rate fixed for | the full term | nothing — reviewed periodically | an initial period (commonly 3, 5 or 10 years), variable thereafter |
| Reference afterwards | — | Euríbor + margin | Euríbor + margin |
| Predictability | complete | none | during the initial period |
| Early repayment | capped compensation, higher in the early years | capped and low | as fija during the fixed period, as variable afterwards |
| Suits | long-term holding, retirement planning | short holding periods, heavy repayment | buyers who plan to sell, refinance or repay heavily within the fixed period |
The Euríbor is a published reference index, not a bank product. What the bank earns is the margin on top — and that is what you negotiate.
The end of the fixed period is not an event. It is an instalment.
With a mixed-rate mortgage the fixed period runs out and the instalment is tied to the Euríbor from that point on. Unlike Germany, Spain has no follow-up financing that gets renegotiated — the contract simply continues, only with a variable rate. Anyone taking a mixed-rate mortgage should therefore know beforehand what they will do when the fixed period ends:
- Sell. Then the structure is ideal — you pay the lower rate during the fixed period and are out before the rate risk starts.
- Repay heavily. Overpayments are legally protected and cheap in Spain. Anyone who has cut the outstanding balance down by the end of the fixed period is barely touched by the variable part.
- Stay and carry the risk. Legitimate — but only if the instalment is still bearable at a considerably higher Euríbor. We run that calculation beforehand, not afterwards.
- Move the loan (subrogación). Changing lender is possible and comparatively straightforward in Spain. It costs time, though, and it assumes you are still financeable at that point — at a greater age than when you signed.
What comes on top for a non-resident
- The choice is smaller. Not every bank offers non-residents all three structures — on larger loans the pure fixed-rate variant sometimes drops away entirely.
- The margin is the negotiating point. It hangs on creditworthiness, loan-to-value and on what else you bring to the bank.
- Product tie-ins (bonificaciones). Insurance, a salary account, cards: they lower the rate and cost money every month. On our current survey of lenders the effect can be up to 1.0 percentage point — whether that pays has to be calculated against the running cost of the products, not assumed.
How long the fixed period should be
Choosing between a short and a long fixed period is not a bet on interest rates — it is a question about your own plan. The period is well chosen when it runs at least as long as the stretch in which you cannot, or do not want to, move.
- A sale is on the horizon. The fixed period should safely cover the intended selling date — with a buffer, because property rarely sells to a calendar. Cut it too fine and you end up in the variable part after all.
- Heavy repayment is planned. Then what counts is how long it takes to bring the outstanding balance down to a size at which a rate rise no longer matters. Overpayments are legally protected in Spain and the compensation is capped.
- Holding for good. Then the mixed structure is not automatically the right one. Anyone who intends to keep the property and has no predictable repayment capacity is only buying a postponement of the rate risk with the fixed period.
- Refinancing pencilled in. A switch is possible, but it assumes you are still financeable at that point — at the age and income position you will have then, not the ones you have now.
With two borrowers, the age limit additionally caps the total term, calculated on the younger of the two — which also affects how much term is even left after the fixed period (how the age limit works for Spanish mortgages).
Overpaying: lower the instalment or shorten the term?
With every partial repayment the bank asks a question many buyers answer in passing: should the instalment fall or the term get shorter? Both are possible, and the difference is substantial.
Shortening the term saves more interest, because the outstanding balance disappears faster — but it keeps the instalment at its current level. Lowering the instalment creates room in the monthly budget, but extends the time over which interest runs. On a mixed-rate mortgage a third point comes in: whoever keeps the balance small by the end of the fixed period defuses the variable rate risk regardless of where the Euríbor stands then. For that purpose, shortening the term is usually the more effective route.
The compensation for early repayment is capped by law and higher during the fixed period than after it — a cost factor, but rarely a reason to skip an overpayment. How the Euríbor itself moves as a reference, and what to compare a margin against, is covered under current mortgage rates in Spain.
Why two offers with the same rate are not the same
The nominal rate (TIN) says little about a Spanish offer until you know what is attached to it. Three figures decide the real cost:
- The APR (TAE) includes costs the nominal rate leaves out. It is the number that makes two offers comparable in the first place.
- The bundled products. A discounted (bonificado) rate is tied to running costs that are not fully contained in the APR figure. Without those annual costs the comparison is incomplete.
- The margin after the fixed period. On a mixed-rate mortgage it is already written into the contract, but rarely emphasised in the sales conversation — and it governs the second, longer part of the term.
Before the notary appointment the bank's binding offer must be in your hands within the statutory period; that time is expressly there for checking. The full process with all deadlines is under how buying property in Spain works, the short version of the term under hipoteca mixta in the wiki.
