This rise, which has been sustained for nine consecutive years, has been particularly pronounced in new contracts. In these, the increase was 22.8% between 2015 and 2024, while existing contracts saw a 9.4% increase.

During 2024, rent in Castellón rose by 4.1%, the largest increase recorded in recent years. New contracts saw a 10.2% increase, while existing leases varied by 2.9%. This statistic, based on income tax declarations, measures the annual evolution of rental housing prices for habitual residence.

The rise in rental prices has been widespread in both large municipalities of Castellón and towns with fewer than 10,000 inhabitants, where the increase was 21.4% between 2015 and 2024. Among the larger municipalities, Vila-real leads the increase with 29.3%, followed by Onda with 28.4%.

In the capital of La Plana, rent grew by 26.3%. Other municipalities with significant increases include Almassora (27.1%), l'Alcora (28%), Nules (18.3%), La Vall d'Uixó (17.3%), Burriana (18.1%), Benicàssim (19.1%), Benicarló (22.1%), and Vinaròs (20.7%).

This increase has worsened since 2022, exceeding 3% annually. Experts point out that this trend coincides with increased market interest in housing, driven by the emergence of tourist housing and room rentals, increased demand, and insufficient rental supply.

Nationally, housing rental prices rose by 3.5% in 2024, the largest increase since 2019, marking ten consecutive years of increases. The Valencian Community recorded one of the largest increases, with 5%, along with the Balearic Islands and Andalusia.
