Is anyone else feeling anxious about the crazy rise in the Euribor rate recently? I certainly am. Watching my monthly mortgage payments climb higher and higher, I knew I had to do something. After some research, I found that switching my mortgage to a different bank with a lower interest rate is a great option. Today, I’m sharing what I’ve learned, hoping it can help others facing the same issue.

Why Consider Refinancing Your Mortgage?
The main reason, of course, is all about the current Spanish mortgage rates and the opportunity to save money! This is especially true for those who signed up for a variable-rate mortgage a few years ago and are now feeling the pinch. There are two main goals when switching banks:
- Switch from a high interest rate to a lower one: For example, if your current fixed rate is 2.5%, but new customers on the market can get 1.8%, then it’s worth considering a switch.
- Change from a variable rate to a fixed rate: For those who are risk-averse and want their monthly payments to remain the same for the next decade or more, locking in a reasonable fixed rate now can provide peace of mind and protection against future Euribor hikes. Even though a mortgage from a Spanish bank at a fixed rate might be slightly higher than a variable one at the moment, the stability is often worth it.
The Main Steps to Refinance Your Mortgage
The whole process isn’t overly complicated, but it does require patience and attention to detail. It basically involves shopping around and then letting the new bank handle most of the paperwork.
- Shop for a new bank: This is the most crucial step. Get quotes from several banks, such as Santander, BBVA, CaixaBank, ING, Openbank, etc., to see what mortgage terms they can offer you. Pay close attention to the TIN (Nominal Interest Rate) and the TAE (Annual Percentage Rate). The TAE is more important as it includes various associated fees and bundled products.
- Submit your application and get preliminary approval: Once you’ve chosen one or more preferred banks, submit your personal documents. The bank will assess your financial solvency and then provide you with a binding offer (oferta vinculante).
- The new bank notifies your current bank: Once you accept the new bank’s offer, they will formally notify your current bank. By law, your current bank has 15 days to make a more competitive counteroffer to keep you as a customer. If they make a better offer, you can choose to stay. If they don’t make a counteroffer or you decline it, the refinancing process continues, which is quite different from other financial decisions like using a loan to buy investment funds.
- Sign the deeds at the Notary (Notaría): The final step is to go to the notary’s office to sign the new mortgage documents. The new bank will handle most of the notary and Land Registry procedures. Once signed, your mortgage is officially transferred to the new bank.
A Comparison of Associated Costs
Switching banks isn’t completely free, but since the new mortgage law came into effect in 2019, most of the costs are now covered by the new bank, significantly reducing what you have to pay. I’ve put together a simple table to help you understand the breakdown:
| Cost Item | Who Pays? | Approx. Cost | Notes |
| Notary fees | The new bank | - | As per law |
| Land Registry fees | The new bank | - | As per law |
| Gestoría (agency) fees | The new bank | - | As per law |
| Property appraisal fee | You (the borrower) | 250 - 450€ | Some banks may reimburse this as part of a promotion |
| Early repayment/cancellation fee from the old bank | You (the borrower) | 0% - 2% of the outstanding loan amount | Check your original mortgage contract carefully for this! |
Finally, a word of caution: always read the fine print on any bundled products (productos vinculados) the bank requires. This can include mandatory home insurance, life insurance, or even requirements for a certain number of monthly credit card transactions. These all affect the true cost of your mortgage. Don’t be swayed by a low headline interest rate alone; consider all factors to find the genuinely best deal. I hope my experience is helpful, and I welcome anyone with experience to add their own tips!
