Affordable housing in Spain: A long-term opportunity for change
Using private capital to provide affordable housing is a growing solution to the housing crisis across Europe. In Spain, it is attracting particular attention; with public bodies increasingly focused on the inadequate level of current provision. The challenge is marked by a structural mismatch between supply and demand, but also by growing policy momentum at national and European levels.
These dynamics have created both complexity and opportunity. While recent geopolitical and economic developments have made investors more cautious, the structural demand for affordable housing supported by public policy continues to make the sector an attractive prospect for long-term, mission-driven capital.
Cristina Pérez Liz, Head of Spain at Octopus Capital, spoke with INREV IQ about this critical issue. The supply-demand gap has widened, ‘because of demographic influences, including the level of migration into larger cities and coastal areas,’ she explains. ‘Thus, there is huge pressure on rents, especially in Madrid, which has not been matched by growth in real incomes.’ Demand is rising across both the most and least expensive districts of major cities, placing additional pressure on affordability.
A slow planning system and insufficient production of new stock compound the issue. Spain needs about 125,000–150,000 homes annually, but fewer than 80,000 are being built. Rental shortages are especially severe, as most housing remains privately owned, leaving limited professionally managed long-term rental options.
A public sector seeking scalable solutions
Spanish public authorities are now tackling affordability at national, regional and municipal levels. However, Cristina notes, legislative change takes time, and local implementation can vary widely. Many are looking to Madrid's Plan VIVE—which uses long-term land concessions to deliver affordable rental housing—to see how it could be adapted to their own locality. The city plans to build 10,000-15,000 new units, while the Spanish President has also announced new funding initiatives for affordable housing, including mechanisms for channelling capital through bodies such as EKO.
Alongside national efforts, the European Commission has increased its focus on housing policy. The introduction of the Affordable Housing Dialogue and forthcoming European Affordable Housing Plan is expected to help standardise definitions, broaden social impact expectations and mobilise EU-level funding instruments. Cristina expects that this will eventually filter down through local administrations and could improve the operating environment for long-term institutional investors.
A strong developer ecosystem — but challenges in long-term capital
A key advantage for Spain, Cristina explains, is that it has an active affordable housing developer ecosystem and increasingly industrialised construction methods that cut timescales. Set against this, the biggest challenge for creating sustainable, affordable housing is the relative unavailability of long-term capital at a reasonable cost. ‘In the UK,’ she says, ‘there is a stronger private pension system which addresses this need. Here in Spain, there aren’t many local investors with long-term capital. We rely on international capital, which is scarcer and more attuned to shorter-term value-add strategies.’
This makes Spain a key market for mission-driven international investors, seeking resilient income, inflation protection and measurable social impact. But success depends on better stability, standardisation, and perhaps more experienced local partners.
The role of operations, technology and partnerships
Across Europe, professionally managed rental housing has shown that strong operations can meaningfully improve tenant outcomes. But in Spain, long-term affordable rental platforms remain limited.
Octopus has a focus on operational platforms, seeing technology as key to efficient building management: streamlining tenant services, monitoring energy consumption and enhancing customer satisfaction. Cristina emphasises that strong partnerships among developers, municipalities, investors and operational managers are essential to scale while maintaining a shared customer-focused ethos.
Measuring social impact
For those thinking of entering the market, measuring the social impact of affordable housing investments is crucial. While Spain’s framework is still developing, organisations like SpainNAB are adapting methodologies from more mature environments like the UK, using indicators such as long-term affordability, tenant mix, rental arrears, energy performance and local impact.
‘We are addressing these challenges by taking lessons from our UK experience, not just in affordable housing but also care homes,’ Cristina explains. Without a national regulator or standardised system, the market relies on collaboration between investors, operators, and authorities. ‘The European Commission’s focus on the area this year should also help the market to mature,’ continues Cristina. ‘There is already a lot of interest from bodies like the EBRD, which have earmarked large amounts of funds for the sector. This should help both local and international capital to reach the market.’
A landscape of opportunity with conditions for progress
Looking ahead, Cristina highlights a few areas she looks forward to seeing improvement from the sector:
- Easier provision of development-ready land
- Simplifying and shortening the planning processes
- Direct leases with local authority rather than individual tenants
- Increased standardisation across PPP models
- Clearer and more consistent rent indexation rules
Overall, prospects are positive for Spanish affordable housing. ‘Momentum is building in the public sector, and many opportunities are emerging,” Cristina says, “Anything that increases stability and makes the sector more suitable for long-term investment will help accelerate delivery. With the right frameworks, we can make real progress.’
