Once a Spanish lender has said yes, you face the next big decision: fixed, variable or mixed? Each structure suits a different kind of buyer, and the right answer depends less on predicting interest rates than on understanding your own plans. Here's how the three options work, and how to think about the choice.
The three rate structures in Spain
Fixed rate (tipo fijo)
With a fixed-rate mortgage, your interest rate, and therefore your monthly repayment, stays the same for the entire term, which for non-residents can run up to 25 years. Whatever happens in the wider economy, your payment doesn't move.
The appeal is certainty. If you're budgeting for a holiday home in a foreign currency, or you simply prefer to know exactly what your Spanish property costs each month, fixing removes an entire category of risk. The trade-off is that fixed rates are typically priced above the starting rate of an equivalent variable product, and you won't benefit if market rates fall.
Variable rate (tipo variable)
A variable Spanish mortgage is expressed as a margin over Euribor, the interbank reference index. For example, "Euribor plus a fixed differential". Your rate is recalculated at scheduled reviews (commonly every six or twelve months): if Euribor has risen since the last review, your repayment increases; if it has fallen, your repayment drops.
Variable products usually start cheaper than fixed ones and can work out cheaper over the life of the loan, but you carry the interest-rate risk. Euribor has moved through wide cycles historically, so a repayment that fits comfortably today needs to still fit if the index climbs.
Mixed rate (tipo mixto)
A mixed mortgage combines the two: a fixed rate for an initial period, then a variable, Euribor-linked rate for the remainder of the term. It gives you payment certainty in the expensive early years of ownership, when you may also be furnishing the property and settling other purchase costs, while leaving room to benefit from the variable market later, or to renegotiate before the fixed period ends.
Fixed vs variable at a glance
| Fixed rate | Variable rate | |
|---|---|---|
| Monthly repayment | Identical for the whole term | Recalculated at each review |
| Linked to Euribor | No | Yes: Euribor plus a fixed margin |
| Starting cost | Typically higher | Typically lower |
| If market rates rise | You're protected | Your repayment increases |
| If market rates fall | No benefit without renegotiating | Your repayment decreases |
| Best suited to | Budget certainty, long-term holds | Rate-tolerant buyers, flexible finances |
A mixed rate sits between the two columns: fixed behaviour first, variable behaviour later.
How to choose: four questions to ask yourself
1. How long will you keep the property?
The longer your horizon, the more interest-rate cycles you'll live through. Buyers planning to hold a family home for decades often value the set-and-forget quality of a fix; buyers who may sell or refinance within a few years have less exposure either way.
2. How would a higher payment feel?
Be honest about your response to a rising Euribor. If a meaningful increase in your monthly payment would strain your budget, especially with exchange-rate movements on top for non-euro earners, certainty has real value. If your income comfortably absorbs fluctuation, the typically lower starting cost of a variable rate may serve you better.
3. What does the rest of your financial picture look like?
A Spanish mortgage rarely exists in isolation. Some buyers deliberately keep financing in place for tax reasons: an outstanding mortgage reduces the net value of Spanish assets for Wealth Tax purposes, as we explain in how a Spanish mortgage can reduce your wealth tax liability. Structure and rate type should be decided together, ideally with your tax adviser in the loop.
4. What are lenders actually offering you?
You can't answer the fixed-versus-variable question in the abstract. You answer it by comparing real offers. Pricing varies meaningfully from bank to bank, and the bank with the best fixed rate is rarely the one with the best variable margin. Because we work with 15+ Spanish lenders, we can put genuine alternatives side by side rather than a single bank's menu. See our mortgage services for how that works in practice.
A note on what this article doesn't tell you
You'll notice we haven't quoted current interest rates or today's Euribor level. That's deliberate: rates move, articles age, and a figure that's accurate this month can mislead you the next. When you book a free consultation, we'll walk you through live terms from the lenders that fit your profile. Once your documents are in, you'll have a written pre-approval within 14 days.
FAQ
What is Euribor and how does it affect my Spanish mortgage?
Euribor is the interbank reference index that Spanish variable mortgages are linked to. A variable rate is expressed as Euribor plus a fixed margin, and your repayment is recalculated at each scheduled review. When Euribor rises your payment goes up; when it falls, your payment goes down.
Can non-residents choose between fixed and variable rates in Spain?
Yes. Non-resident buyers have access to fixed, variable and mixed rate products, typically at up to 60–70% loan-to-value with terms of up to 25 years. Which structures are offered, and on what terms, varies from bank to bank, which is why comparing multiple lenders matters.
What is a mixed-rate Spanish mortgage?
A mixed mortgage combines an initial fixed-rate period with a variable, Euribor-linked phase for the remainder of the term. It offers payment certainty in the early years while keeping the potential to benefit from the variable market later.
