Asufin’s housing affordability index rose to 106.86 points between April and June 2026, more than five points above the previous quarter.

Buying a home in Spain became less affordable in the second quarter of 2026 as interest rates rose, demand from foreign buyers increased and borrowers took on more debt, according to the quarterly index compiled by Asufin.

Housing supply was the only component of the index to offer some relief. A total of 24,991 permits were issued for new construction, up 9.3% from a year earlier. Higher interest rates, larger average mortgages and stronger foreign demand all made it harder to buy a home. An increase in home sales and new mortgages also added to demand-side pressure.

The average interest rate across fixed- and variable-rate mortgages rose to 2.96%. The average monthly mortgage payment increased by €52.19 to €842.12 per €100,000 borrowed. As a result, the share of the average monthly salary needed to cover the payment rose from 33.11% to 35.30%.

Foreign buyers accounted for 15.98% of all home sales during the quarter, the highest share since records began. That represents around 26,800 transactions, up 11% from a year earlier.
