Octopus Capital, an asset manager investing in the people, ideas, and industries that will change the world, today publishes a report, one of the first from an international investor perspective, that looks at affordable housing in Spain. This comes as the market reaches a critical inflection point.
Through industry research, conversations with local stakeholders, and Octopus Capital’s experience in adjacent sectors, the report presents a holistic view of where the market is today. The report explores the scale of the opportunity for affordable housing in Spain, the models that work, and the role institutional capital can play in driving lasting change.
The report firstly highlights how over the past decade, average rents in certain parts of Spain have nearly doubled, while average wages have only risen by about 20%1. This growing gap between fast-rising housing costs and slower income growth is pushing many households into affordability stress.
At the same time, Spain’s population is growing faster than its housing stock. In 2022 it welcomed over 800,000new residents – its fastest population growth in more than a decade2. Most settled in urban or coastal regions where housing is already in short supply. Housing completions also lag far behind need. In 2023 under 100,000 new homes built3 versus300,000 needed. The deficit could reach 680,000 by year-end4.
Like many European markets, Spain’s residential sector is also navigating tighter financing conditions. Interest rates and yields have been close, requiring higher equity inputs to make new developments viable. Higher construction costs and lingering skills shortages make delivery more difficult, with less headroom for affordability.
Planning and zoning regulations add another layer of complexity. Spain’s 17 autonomous communities each set their own frameworks, making national roll-out challenging. However, some regions are showing how innovation is possible when those frameworks are clear.
One good example of innovation that the report pulls out is Plan VIVE in Madrid, which uses long-term concessions to unlock land and deliver affordable rental housing through competitive tenders. More than 6,000 homes are already underway, with a total programme target of 25,0005.
There’s momentum for the sector at an EU level too. The European Commission has introduced the Affordable Housing Dialogue to coordinate action across national, regional and city levels to make affordable, sustainable and decent homes available to everyone.
Beyond policy, the report looks at how Spain’s macro profile is a major catalyst for capital. The economy is resilient, its urban centres are large and growing, and rental demand is deep. Investor confidence reflects this momentum – Spain ranked second in Europe for real-estate investment attractiveness in 2025, behind only the UK and ahead of Germany and France6.
Institutional capital is well positioned to bolster affordable housing solutions. As an asset class it is structured for the long term — offering stability and resilience. Demographic demand is also strong, meaning occupancy levels are likely to remain high, adding another layer of security for investors.
Lastly, there’s the measurable social impact, accelerating the delivery of affordable homes to those that need it most, and environmental impact, with energy-efficient homes cutting carbon, reducing household bills and improving resilience for the future.
Together, these catalysts are starting to offset the constraints, setting up the right conditions for investment. Investor appetite for UK affordable housing is well established, and the report suggests that the Spanish market is poised to become one of Europe’s next major opportunities.
The report ultimately aims to help bring about progress for Spain’s affordable housing sector. It suggests several critical enablers that can accelerate this journey:
- Stronger project pipelines, offering continuity and visibility across regions, will help investors plan and commit capital with confidence.
- Transparent frameworks for the use of public land – including clear documentation, standardised terms, and well-defined affordability criteria – will create the consistency and trust needed to keep building large-scale investment.
- Greater consistency in planning processes across regions can further strengthen investor confidence, reduce delays, and improve delivery timelines. Models that reward quality and long-term alignment – rather than purely lowest-cost bids – can attract patient capital with a social purpose.
While regional variation is inevitable, a shared vision and stability would help coordinate efforts, attract international investors, and create a scalable, investable sector. None of these elements are unrealistic – and as the report underscores, early signs of progress are already visible in the market.
Ed Clough, Head of Real Estate, Octopus Capital
“At Octopus Capital, we invest in sectors where long-term thinking and social purpose go hand in hand. We focus on areas where responsible capital can drive positive outcomes, which is exactly why we entered the affordable housing space back in 2023. We then opened our office in Spain the following year to bring that same thinking to one of Europe’s most dynamic housing markets.
“We believe affordable housing, whether it’s in the UK or Spain, is essential social infrastructure: it strengthens communities, supports economic growth, and meets a fundamental human need. What this report shows is that Spain’s landscape is unique but ripe for meaningful action, and that with the right frameworks and partners, capital can flow where it’s needed most.”
Cristina Perez Liz, Head of Spain, commented:
“To date, the strategies investing into affordable housing in Spain have targeted high returns, with short term exits in sight. But now the market is at a turning point. The need is undeniable, the policy direction is supportive, and investors are increasingly looking for strategies that combine stable returns with tangible outcomes. We believe this is a long-term opportunity – one that requires expertise, strong local relationships, and a deep understanding of both the market and the people it serves. A committed partner to the sector can ensure a strong level of customer satisfaction, which in turn, should enhance performance for investors over the long-term.
“With our permanent presence in Madrid, we see both the need and the opportunity to make a lasting impact, and we’re ready to work alongside stakeholders on the ground to help realise it.”
