How do I choose between fixed and variable rates for a mortgage?
-
Should I take a mortgage with fixed or variable rates?
Fixed-rate mortgages and variable-rate mortgages are the two main categories of mortgages you can pick. Of course, there are many other possibilities between the two.
-
Why would you take a fixed-rate mortgage?
A Fixed rate mortgage has the advantage that whatever the market conditions will do in the future, it will remain the same. To get that advantage, you will on average pay a higher rate than on a variable-rate mortgage, for instance, as of May 2025, mortgages with variable rates are issued at rates of 2.9% while those with fixed rates are issued with 3.0% for an average length of 24 years.As we are writing, May 2025, Inflation rate has stabilized in Spain: the level as of May 2025 is 2.5%.
-
Why would you take a mortgage with a variable rate?
It could be because it is less expensive and because you don’t see inflation or rates going higher or because you are comfortable financially and can face higher rates. Another reason for variable rates to be lower is that for the banks issuing them, it matches their sources of funds (saving’s accounts).
So, to sum up, if you want safety, take a fixed-rate mortgage. If you see inflation spiking or interest rates going higher (in general due to a strong economy) you could as well go for a fixed-rate mortgages. Of course, the longer your mortgage is the higher your risk will be.
Don’t hesitate to ask to your Spanish mortgage broker a pricing with both and compare both offers.

Currently, 64% of mortgages are issued with fixed rates, a slight decrease from the 75% peak we saw in late 2021.
