"Residential supply has responded inadequately to the growth in demand", the Bank of Spain states in its 2025 annual report on the performance of the national economy. The institution estimates that a total of 750,000 new homes would be needed to close the gap between newly formed households and the available housing stock.
Its experts warn, however, that this situation is not the same in every Spanish province. While Ávila has 58.2% of properties in its housing stock that could be brought onto the residential market, Madrid is limited to just 9.9%, compared with a Spanish average of 27.1%. The areas hardest hit after the capital are Barcelona, Alicante, Valencia, Murcia and Málaga.
