Fixed, variable or mixed? The definitive guide to choosing your mortgage in 2026

Couple reviewing their mortgage documents at the table at home

Choosing between a fixed, variable or mixed mortgage is the most important financial decision of your life. In 2026, with the Euribor stabilizing and fixed rates at their most competitive in recent years, the right choice can mean a difference of tens of thousands of euros over the loan.

What has changed in 2026?

The Euribor has experienced a significant drop from the 2023 highs, settling at more moderate levels. This has changed the balance between the three mortgage options, making the decision more nuanced than ever.

Fixed Mortgage — Who is it ideal for

You know exactly what you'll pay each month
Ideal if you're risk-averse
Perfect for long terms (+20 years)
Recommended if your income is tight

Variable Mortgage — Who is it ideal for

Lower initial payment
Ideal if you plan to make early repayments
Recommended if Euribor is high and falling
For profiles with higher risk tolerance

Mixed Mortgage — Who is it ideal for

Security in the first years + flexibility later
The most popular in Spain in 2024-2025
Ideal if the fixed period coincides with your highest family spending
Balance between cost and peace of mind

Duplo Capital's recommendation

In 2026, for most profiles we recommend first analyzing a mixed mortgage with a 5-10 year fixed period, given the current Euribor context. However, each profile is unique and deserves personalized analysis.
