Fixed, variable or mixed mortgage in Spain 2026: which suits you
Updated comparison of fixed, variable, and mixed-rate Spanish mortgages in 2026. Current rates, advantages, risks, and which to choose by buyer profile.
Your mortgage is probably the longest financial contract of your life. Choosing well between fixed, variable, and mixed can save you €20,000-40,000 over 30 years.
The 2026 context
After the 2022-2024 highs (Euribor over 4%), 2025-2026 has stabilised. Current reference rates:
- Euribor 12 months: 2.40-2.60% (stable since Q3 2025)
- Average top-bank fixed TIN: 2.90-3.40%
- Average variable TIN: Euribor + 0.75-1.00%
- Mixed TIN (5-10 years fixed): 2.80-3.20% in fixed period
ECB forecasts point to rate stability through 2026 with possible mild cuts in 2027.
The three modalities
Fixed-rate mortgage
Constant payment for the entire mortgage life.
Pros: total peace of mind, ideal for stable incomes with no margin to absorb increases. Cons: TIN initially 0.40-0.70% higher than variable; if rates fall, you don’t benefit.
Variable-rate mortgage
Payment adjusts every 6 or 12 months based on Euribor.
Pros: lower initial TIN; you benefit automatically when rates fall. Cons: unpredictable payment. A 2-point Euribor rise can push the payment up 25-30%.
Mixed-rate mortgage
Fixed rate for an initial period (5, 10, 15 or 20 years) + variable thereafter.
Pros: peace of mind in the early years (most volatile after a purchase) and flexibility long-term. Cons: when it switches to variable, you face Euribor risk again.
Which to choose by profile
Profile A: First-time buyer, 30-40, stable income → Mixed 10-year fixed + variable. Stability in tense early years, then flexibility.
Profile B: 50+ buyer, high income, 15-20 year horizon → Fixed or short mixed (5 years). Prioritise calm near retirement.
Profile C: Buy-to-let, traditional rental, can absorb rises → Pure variable. Lower Euribor in cycles; rent inflation offsets rises.
Profile E: Total risk aversion, tight budget → Pure fixed. The premium is your peace-of-mind insurance.
Bank-tied products: the detail that changes everything
| Product | Typical discount | Worth it? |
|---|---|---|
| Salary direct debit | 0.10-0.30% | Almost always yes |
| Home insurance with bank | 0.10-0.20% | Compare premiums |
| Life insurance with bank | 0.15-0.40% | Almost never |
| Credit card | 0.05-0.10% | Yes if you’d use it anyway |
| Pension plan | 0.10-0.15% | Usually no |
Real tip: bank-tied life insurance often costs 40-80% more than equivalent external policies.
My final advice
Don’t go to one bank only. Get offers from 3-4 entities with your mortgage file ready (payslips, employment history, tax returns, contract). Negotiate with each using the best of the rest. This typically gets you 0.15-0.40% TIN below accepting the first offer.
