Large Landlords in Spain Increase Rents at Twice the Rate of Small Owners

A recent analysis of Spanish rental data reveals that the size of a landlord’s portfolio significantly impacts the cost of housing for tenants. Between 2019 and 2023, property owners managing five or more rental units raised prices at nearly double the rate of those who own only a single property.

Rental Market Divergence

The study, published by the EsadeEcPol research center, examined tax records for over 780,000 rental agreements declared by individuals across Spain. The findings highlight a clear disparity in pricing behavior based on ownership scale.

Owners with portfolios of five or more properties increased their rents by an average of 13.5% during the four-year period. In contrast, small-scale landlords—those with only one apartment on the market—implemented average rent hikes of 7.2%.

The data suggests that the rental market gap in Spain is defined not only by geographic location or the size of a property but also by the professional profile of the landlord. While inflation and broader market trends have affected all property owners, the analysis indicates that larger entities have exerted more upward pressure on rental costs.

Broader Market Implications

The EsadeEcPol report provides a detailed look at how market concentration influences affordability. By utilizing tax data, researchers were able to track specific pricing trends across a massive sample size, offering a precise view of landlord behavior in the private rental sector.

Why it matters: This data underscores the role of market concentration in housing affordability. For policymakers, understanding the behavior of large-scale landlords is critical, as these entities exert a disproportionate influence on rental inflation compared to individual property owners.
