MADRID — Renting a room in a shared flat is becoming an increasingly common fallback for tenants in Spain, according to new research from property platform Fotocasa. The study, based on data from the first half of 2026, shows that 3.2% of Spaniards have rented or looked for a room, up from 2.8% a year earlier.
The report, titled Profile of people who share housing, attributes the rise not to lifestyle choice but to financial necessity. “Tenants are not looking to share a flat because it is their first choice, but because the market forces them to adjust their expectations to what they can afford,” said María Matos, head of Research and spokesperson for Fotocasa. “Renting a room has become the plan B for those who cannot secure a conventional tenancy.”
Two markets, one direction
The study identifies a clear overlap between the market for whole properties and the market for rooms — but only in one direction. Among those who have rented or looked for a room, 34% have also searched for or rented an entire property in the past 12 months. In other words, one in three room-seekers is aiming for something bigger. In contrast, only 11% of those who have searched for or rented a whole flat have also considered a room.
This asymmetry suggests that room sharing is increasingly a forced compromise rather than a preferred option. The demand for whole homes has remained practically stable, with around 10% of the active population in that segment. When both markets are combined, total rental demand now reaches 12% of the population — almost half a percentage point more than in 2025, a rise that Fotocasa describes as moderate.
Matos sees these numbers as part of a wider trend: the pressure on renting, she says, “is spreading across the entire market.” More and more people need to rent, and “given the lack of supply and prices that are still very high,” they are abandoning what they were originally hoping to find.
The findings come against a backdrop of Spain's housing gap, where wages have risen but home prices have outpaced them. In cities like Madrid, Barcelona, and Valencia, average rents have climbed steadily, pushing many young workers and even middle-income families into shared accommodation.
The trend is not confined to Spain. Across southern Europe, from Lisbon to Athens, similar dynamics are playing out as tourism and short-term rentals squeeze long-term supply. In Spain, the government has introduced measures to cap rents in some regions, but the impact has been limited so far.
For those who do turn to room sharing, the experience varies widely. Some find it a temporary solution while they save for a deposit; others see it as a permanent reality. The Fotocasa report notes that the profile of room-seekers is diverse, including students, young professionals, and even older workers who have been priced out of the conventional market.
Matos warns that the trend could have long-term consequences. “When a significant share of the population cannot afford a home of their own, it affects not just their quality of life but also their ability to plan for the future,” she said. “This is a structural issue that requires a coordinated response from all levels of government.”
The report also highlights a mismatch between supply and demand. While the number of people looking for rooms has grown, the availability of shared flats has not kept pace, leading to higher room prices in many areas. In Madrid, for example, the average room rent has risen by more than 10% year-on-year, according to separate data from idealista.
As the rental market tightens, the line between conventional renting and room sharing is blurring. For many Spaniards, the question is no longer whether they will share a flat, but for how long.
