Spain’s supply of long-term rental homes has fallen by 44% in just seven years, new research has revealed.

The number of permanent rental properties advertised on Idealista fell by almost 393,000 between 2018 and 2025, according to a new study by the property portal.

Idealista recorded 902,664 permanent rental listings during 2018, compared with 510,901 in 2025, representing a decline of 391,763.

The contraction affected 41 of Spain’s 50 provinces and was even more pronounced in several major cities.

In Malaga city, the number of listings fell by 35.8%, from 17,637 in 2018 to 11,322 last year, in a loss of 6,315.

Across Malaga province, however, the decline was much smaller at 4.8%, with listings dropping from 48,286 to 46,524.

Madrid and Barcelona record biggest falls

Madrid province lost 137,411 long-term rental listings, representing a 54% fall.

Barcelona recorded an even steeper decline of 74%, with supply dropping from 155,719 to 39,568.

They were followed by Valencia, which lost 20,118 listings; Sevilla, down 17,368; and Asturias, which recorded 10,411 fewer.

Among provincial capitals, Madrid lost 117,558 listings and Barcelona 94,130.

Sevilla city’s total fell from 23,960 to 11,695, while Granada dropped from 15,577 to 8,114.

Not every part of Spain experienced a contraction. Alicante province gained 4,312 listings, while increases were also recorded in Castellon, Jaen, Caceres and La Rioja.

Idealista said its analysis counted active permanent-rental adverts published during 2018 and 2025 using the same methodology.

Seasonal lets and individual room rentals were excluded.

The figures therefore measure listings appearing on Idealista during each year, not the total number of rental homes physically existing in Spain.
