The housing crisis in Spain, particularly in cities like Madrid, is worsening, pushing many, including pensioners like Francisco Carrillo, into homelessness due to high rental prices and a shortage of social housing exacerbated by holiday lets on platforms like Airbnb. There has been a 24% increase in homelessness since 2012, affecting 28,000 individuals, with around 45% of renters facing the risk of poverty or social exclusion. Spain's social housing stock is only 1.5% of all homes, well below the European average of 9%, leading to fierce competition for private rentals, with 40 responses per listing in Madrid. The government plans to add 184,000 public housing units in the next three years, aiming to match the European average by 2027, but an additional 1.5 million homes may be needed to achieve this target. The crisis extends to popular tourist destinations like Tenerife, where a tourism boom has led to the emergence of shanty towns, forcing even essential service workers to live in caravans or makeshift homes due to soaring property prices.
