Spain’s housing market is under strain as new households form much faster than new homes are built. That gap is pushing property prices and rents to new highs, especially in the country’s largest cities.
Economist Gonzalo Bernardos warns that buying or renting in Spain is getting harder. Household formation is outpacing the supply of new homes. In 2025, Spain added about 241,000 new households, but only 91,900 new homes were finished. The shortfall reached nearly 149,000 homes in one year, more than 2.6 new households for every completed dwelling.
Fotocasa reported that in the first half of 2026, only 14% of people searching for housing in Spain were looking to rent, a historic low for rental demand share. The figure came from the company.
This is more than a statistical blip. The Bank of Spain’s latest annual report estimates a further deficit of around 150,000 homes for 2025 and a total gap of 750,000 units since 2021. The problem is most severe in six provinces: Madrid, Barcelona, Alicante, Valencia, Murcia and Málaga. Together, they account for over half the national shortfall.
Prices are rising quickly. The National Statistics Institute’s Housing Price Index ended 2025 up 12.9% from the previous year. Second-hand homes rose 13.1%, while new builds went up 11.2%. Rents are climbing too, with new lease contracts up nearly 5% in real terms over the year. Moving out is becoming less realistic for many young adults: in 2025, 44.3% of Spaniards aged 26 to 34 still lived with their parents, and nearly half said unaffordable housing was the basic reason.
Demographics are shifting, too. Spain’s average household size is shrinking, from 2.50 people per home in 2024 to a projected 2.32 by 2039. The number of single-person households is expected to jump by 42% over the same period. Even with only modest population growth, demand for separate homes is rising faster, driven by changes in family circumstances and age, as well as emancipation and immigration.
The National Statistics Institute (INE) confirmed a new peak in housing prices in the second quarter of 2026, with a 12.2% year-on-year increase. The rise was especially pronounced in the secondary market, where prices rose by 12.9%; new builds saw a 7.4% increase. The figures were reported by the National Statistics Institute (INE).
The construction sector is growing in economic terms, yet too few new homes are being built. In 2025, construction made up 5.35% of Spain’s GDP, higher than in recent years but still only half its share before the 2008 crisis. Much of the activity focuses on civil works and renovations, alongside non-residential projects, rather than new housing where it’s needed most.
Several obstacles are slowing new construction: a shortage of ready-to-build land and slow urban planning, compounded by long permit processes and a lack of skilled workers. Even if construction speeds up, the time between planning and completion means today’s demand won’t be met for years. The Bank of Spain says higher prices alone aren’t enough to trigger a quick supply response.
Location adds another layer of difficulty. Spain still has about 450,000 unsold new homes left from the last property boom, but many are in areas with little demand or don’t fit what buyers want. A vacant home in a shrinking town doesn’t help renters in Madrid or Málaga. As recent reporting shows, a mismatch between available housing and real demand can leave vulnerable groups in poor conditions, even as empty homes sit unused elsewhere.
For policymakers, the challenge is clear: Spain can’t repeat the mistakes of the pre-2008 building boom, and it must address the urgent need for more homes in the right places. Millions of dwellings are not enough if they aren’t where people want to live. Until the supply gap closes, prices will stay high and many will struggle to find housing. The shortage is setting the rules, while a generation loses opportunities so of inaction.
