In 2026, Madrid has surpassed 75,000 property owners who each own at least three homes, alongside over 10,000 who possess ten or more properties. This surge signifies a worrying trend in the real estate market, where a substantial number of individuals, funds, and companies control a large portion of the housing stock. This phenomenon has serious implications for young people and families struggling to afford housing in a city known for its skyrocketing rents and buying prices.

The data compiled by EL PAÍS from the Ministry of Finance illustrates the stark contrast between the property ownership landscape and the daily struggles of renters in the city. With the market being increasingly dominated by large landlords, both natural persons and investment groups, the availability of affordable housing continues to dwindle. This concentration of ownership leads to rising prices, leaving many potential buyers and renters in a tight spot, trapped in what can only be described as housing 'rat holes'.

As the number of property owners with multiple houses increases, concerns mount over the future of housing accessibility in the Madrid region. The implications of these statistics extend beyond immediate economic impact, suggesting potential challenges for social stability as more individuals find themselves unable to secure adequate living conditions. The current situation calls for urgent policy considerations to address the imbalance in property ownership and the urgent need for affordable housing solutions in Madrid.
