European Affordable Housing Investment Potential

Resource context

“European Affordable Housing Investment Potential” is a research report published by JLL (Jones Lang LaSalle), a global real estate and investment management professional services firm. The document brings together EMEA living research and capital markets perspectives and examines how affordable housing systems across Europe are structured, where unmet need is concentrated, and what scale of public and private investment would be required to expand supply.

How affordable housing is defined and delivered

Across Europe, affordable housing has no single legal definition and varies by tenure, tenant criteria, and providers. Many governments frame affordability as rents capped at around 30–35% of income. Delivery models span public-owned social rented homes (often with income limits), regulated private rentals, and intermediate tenures such as discounted rent or part-rent/part-own products. Supply is also shaped by developer obligations in new schemes, government loans and grants, land contributions by local authorities, and tenant housing allowances.

Scale of the sector and long-term supply trends

JLL estimates there are about 26.4 million affordable homes across the UK and EU, representing roughly 11% of households. This share has declined from 12% over the past decade, with total stock growing only around 1% (about 262,000 homes). Country mixes differ significantly: the Netherlands has one of the highest shares (28%), while southern markets such as Portugal (2%) and Spain (3%) have low shares, reflecting historical prioritisation of home ownership and public stock sales in some countries.

Affordability pressures and housing cost overburden

The report links growing need to broader market shifts: over the last decade, households increased by around 7% in the UK and EU, while the private rented sector expanded faster than owner-occupation. Price dynamics also tightened affordability. For new city lets, rents rose about 19% from Q1 2016 to Q1 2022, alongside wage growth of about 23% and house price growth of about 38%. From Q1 2022 to Q2 2024, rental growth accelerated to around 21% while wages grew about 14%, and house prices increased only about 5%.

Real affordable housing need and investment requirement

Using the EU definition of housing cost overburden (households spending more than 40% of disposable income on housing costs), JLL estimates about 23 million households—around 10% of households in the UK/EU region—are overburdened. Meeting this level of demand would require the affordable sector to almost double, from 26.4 million to about 49.4 million homes. For urban areas, the report estimates that providing homes at a 20% discount to local market values implies a potential investment requirement of up to approximately €5.3 trillion, with around 70% of the required homes concentrated in cities.

Investment markets and the role of private capital

Institutional investors currently represent a very small share of affordable housing ownership (estimated around 0.3%), but transaction activity has been rising. Affordable housing investment peaked at about €2.6 billion in the last year covered, equating to roughly 9% of multi-housing investment (up from about 3% in 2022). Activity has been dominated by domestic buyers (around 80%). The report highlights that investment viability often depends on subsidy frameworks that support lower rents and project economics, including grants, low-interest loans, green and sustainability-linked financing, and planning-led delivery requirements.

Policy tools and emerging supply approaches

The report notes varied national approaches, including developer requirements (e.g., minimum shares in new projects), rent regulation and indexation in mature markets, and large-scale programmes such as England’s Affordable Homes Programme (£11.5bn/€13.8bn aiming for 180,000 homes over five years). It also points to innovation such as offsite construction (e.g., Madrid’s Plan Vive) and repurposing strategies like office conversions (e.g., initiatives cited for Madrid and Paris), alongside EU-level discussions on an Affordable Housing Plan and reporting frameworks that could increase transparency for socially sustainable investment.
