a. What is the state of the Spanish mortgage market?
The Spanish mortgage market is slowly recovering. There was a sharp decline in 2023, but mortgage signings grew 30% year-over-year, driven by the drop in the Euribor. Consequently, the number of buyers increased, boosting the market. However, it remains a challenge: House prices increased by 8.1% in the third quarter of 2024, bringing the average mortgage amount to €150,000. The supply of new homes remains limited, especially in urban areas.
Number of mortgages signed in Spain
b. What requirements do Spanish banks require of customers to obtain a mortgage loan?
Spanish banks are being more stringent when granting mortgage loans, compared to the European average.
Minimum requirements:
Payment capacity
20% of the property's value
25 to 55 years of age
No prior debts
Maximum expenses = 35% of income
Among others
