Hello everyone, I’ve been running myself ragged lately trying to get a mortgage to buy a home. After several meetings with a bank manager, I got stuck on one word: avalista, which is what we commonly call a guarantor. I believe many of you might have encountered this, especially as foreigners, since banks have stricter risk assessments for us. Today, I’m sharing what I’ve learned about the role of a Spanish mortgage guarantor, so we can all discuss it.
Banks don’t just ask for a guarantor randomly. It usually happens when they perceive a slight risk in your repayment ability. For example, if you have a temporary work contract, your down payment isn’t high enough, or your income stream isn’t considered ‘stable’ enough. In these cases, to mitigate their own risk, the bank will ask you to provide a ‘backup payer’—the guarantor.
What qualifications are needed to be a guarantor?
Becoming a guarantor isn’t as simple as signing a paper. The bank’s vetting process for a guarantor is just as rigorous as it is for the borrower, if not more so. I confirmed with my manager at BBVA, and here are the basic requirements:
| Criteria | Specific Requirements |
| Financial Stability | Must have a stable and sufficient income. The bank will review payslips and personal income tax returns. |
| Credit History | Must not have any record of bad debts or defaults. |
| Asset Status | Owning property or other real estate is a huge plus, especially if it’s mortgage-free or the mortgage is nearly paid off. |
| Age | Must not be too old. The bank needs to ensure the guarantor will still be of working age by the time the loan is fully repaid. |
Don’t overlook the risks for the guarantor
What does it mean to be a guarantor? Simply put, if the borrower defaults, the bank will go directly after the guarantor. The guarantor will have to use their own income or even assets to repay the loan. This is no joke; it can directly affect the guarantor’s own future borrowing capacity and financial life. Therefore, whether you’re looking for a guarantor or acting as one, being a mortgage guarantor is a heavy responsibility, and you need to be clear about the terms even with close family. A friend of mine had their own mortgage application affected because they acted as a guarantor for a relative. It can be a real trap, but you know what I mean.

In Spain, it’s quite common for banks to request a guarantor, but don’t agree to it lightly. Make sure you read all the terms and conditions carefully, especially the parts about the scope and duration of the guarantor’s liability.
