According to data from the Rental Observatory, promoted by the Alquiler Seguro Foundation, this figure represents a 26% increase compared to the same period last year and a 4% increase since the end of 2025. Demand is especially concentrated in large cities and their metropolitan areas.

Barcelona is consolidated as the city with the highest tension, registering 453 interested people for each apartment that comes onto the market. Although this value represents a slight quarterly decrease, the Catalan capital remains far above other provinces. It is followed by Vizcaya, with 191 interested parties, and the Balearic Islands, with 147. Other provinces exceeding one hundred interested parties include Zaragoza (127), Álava (122), Madrid (118), Las Palmas (115), Girona (109), and Santa Cruz de Tenerife (101).

The report highlights a

from Madrid and Barcelona to neighboring provinces and metropolitan areas. This explains the high pressure in areas such as Tarragona (93), Guadalajara (92), Toledo (73), and Lleida (58). The Valencian Community also shows high levels, with Valencia (85), Alicante (47), and Castellón (39) among the provinces with the highest demand.

At the other extreme, provinces such as Badajoz (12), Ávila (11), and Jaén (10) maintain demand within what are considered normal parameters, with fewer than 25 interested parties per property. The lack of supply continues to be a key factor, with a projected 2.1% drop in the rental housing stock for 2026, which would mean 14,391 fewer properties.

This escalation of tension is also reflected in prices. The average rent in Spain reached 1,205 euros per month in the first quarter of 2026, a 5.1% increase from the previous year. Twelve provinces already exceed the 1,000 euro per month barrier, including the Balearic Islands (1,676 euros), Barcelona (1,644), Madrid (1,606), Valencia (1,159), and Alicante (1,022).
