In the last two decades, the proportion of the population that rents their dwelling has increased significantly in Spain. Whereas in 2007 only 19.4% of the population lived in a home that was not their own, by 2024 this figure had risen to 26.3%. This change implies a partial convergence towards the levels observed in the EU, where in 2024, 31.6% of the population lived in rented accommodation.
In this article, we analyse the dynamics of rents in Spain using internal CaixaBank data on rent payments, duly anonymised and aggregated. We analyse the payer-issuer relationships by distinguishing between new rental contracts and existing contracts with rental price updates, allowing trend shifts to be captured more precisely. Using this information, we construct rental price indicators. This approach allows us to complement traditional data sources with high-frequency and granular measures.
