I’ve finally sorted out my mortgage, and it was quite a rollercoaster ride. It feels like bank approvals are getting stricter these days. I wanted to share my personal experience dealing with the bank, hoping it can be a reference for anyone preparing or planning to get a home loan in the future.
What Are Banks Really Calculating?
After several conversations with bank managers and facing a few rejections, I’ve finally figured out their core approach to evaluating loan applicants. To put it simply, the bank just wants to ensure you can repay the loan on time and minimize their risk. They ‘profile’ you from several angles. I’ve summarized the most important points: your earning capacity, your existing debt, and how much of your own money you’re willing to put down for the property.
Key Assessment Metrics
Income Stability and Type: This is of the utmost importance for determining Spanish mortgage rates. Banks favor employees with permanent contracts (contrato indefinido), especially those who have passed their probationary period. If you are self-employed (autónomo), they will scrutinize your finances more closely, usually requiring one to two years of tax returns and quarterly IVA declarations to prove your income consistency. For someone like my friend who just changed jobs or is on a temporary contract, the application process is much more difficult.
Debt-to-Income Ratio (DTI): This is a critical metric for Spanish bank loans. The bank calculates the total of all your monthly debt payments and compares it to your monthly income. The Bank of Spain recommends this ratio should not exceed 35%. If your new mortgage payment plus existing debts surpasses this threshold, it’s a major red flag. Before applying, it’s a good idea to pay off any small, outstanding credit card installments to effectively lower your DTI.
Down Payment and Savings Capacity: Banks in Spain typically finance a maximum of 80% of the property’s value, meaning you need to provide the remaining 20% as a down payment. But don’t forget, on top of the down payment, there are taxes and fees that amount to an additional 10%-12%. Therefore, you should be able to demonstrate that you have savings equivalent to about 30%-32% of the property price. Bank statements that show a consistent pattern of saving are a huge plus.

Below, I’ve put together a simple table listing the basic documents banks usually require. It’s best to prepare them in advance:
| Document Type | Employee | Self-Employed |
| Identification | NIE/TIE, Passport | NIE/TIE, Passport |
| Proof of Income | Last 3-6 months’ payslips | Last 1-2 annual tax returns |
| Proof of Employment | Employment contract, Work life report (Vida Laboral) | Recent quarterly tax declarations |
| Proof of Assets | Bank statements, Other proof of assets | Bank statements, Other proof of assets |
| Credit Report | Bank may run the check, a process also used for loans for investment funds. | Bank may run the check themselves. |
The whole process is about proving to the bank that you are a reliable and creditworthy client. The more thoroughly you prepare your documents and the smoother your communication with the bank manager, the higher your chances of success. I hope my experience helps, and I wish everyone success in securing their dream home!
