Overview of the Research Brief
This brief, authored by Aidan Regan and published by the Progressive Politics Research Network, analyses how homeownership can be framed as a progressive policy in advanced economies. It draws on recent data from OECD, Eurostat, and national surveys to illustrate the growing affordability crisis and its political implications across Europe.
Housing Affordability Crisis in Europe
Across OECD countries, housing consumes 20â30 % of disposable income, with owners and renters alike facing rising costs. Between 2010 and 2023, average EU house prices rose by nearly 50 % while rents increased around 22 %. Ireland experienced the steepest price surge (â 70 %), whereas Italy and Greece saw declines. Homeownership rates remain high (â 70â75 % of households), but ownership is increasingly concentrated among higherâincome groups; the top income quintile owns 85â90 % of homes, while the bottom quintile lags far behind.
Key Data on Ownership and Income Gaps
- Ownership by income quintile (2022): top quintile 85â90 %; bottom quintile markedly lower, especially in the US and France.
- Mortgageâfree ownership exceeds 50 % in many EU nations, highlighting the role of asset inflation.
- Houseâprice growth has consistently outpaced wage growth since 2000, widening the affordability gap.
Mortgage Finance Regimes and Their Impact
Four historic mortgage finance models shape national outcomes:
- Direct finance (selfâbuild)
- Depositâbased finance (building societies, e.g., UK, US)
- Bondâbased finance (mortgage banks issuing covered bonds, e.g., Germany, Denmark)
- State finance (public subsidies and direct funding) Bondâbased and stateâled systems tend to sustain stronger rental sectors and more stable priceâtoâincome ratios, whereas depositâbased regimes are linked to higher price volatility and speculative cycles.
Public and NonâProfit Housing as an Anchor
Nonâprofit and public housing accounts for only 7â8 % of European housing stock, yet where it is substantial, affordability improves markedly. Viennaâs municipally owned or cooperative housing covers about 40 % of residents, keeping rents low. Singaporeâs publicâownerâoccupied flats house over 80 % of its population. Paris aims to raise publicâbacked housing to 40 % by 2035 through preâemptive rights and quota requirements.
Policy Recommendations for Sustainable Homeownership
- Expand nonâprofit/public housing â increase state capacity to build and manage homes at scale.
- Reform mortgage finance â adopt coveredâbond models, sharedâequity schemes, and publicâbacked lenders to lower borrowing costs without fueling speculation.
- Bridge renterâowner divide â implement tenantâprotection tools (e.g., Germanyâs Mietspiegel) and pathways such as leaseâtoâown, starter loans, and sharedâownership programs.
- Reframe housing as public good â treat housing as essential infrastructure, enabling longâterm borrowing and landâvalue capture to fund affordable construction.
Political Stakes for Progressive Parties
Unaffordable housing erodes trust in government and boosts support for antiâestablishment parties. Surveys (Eurobarometer 2024, Gallup 2025) rank housing costs among the top concerns influencing voter behavior. Progressive parties that deliver affordable housing can rebuild coalitions of younger urban voters, renters, and aspiring owners.
European Outlook and Comparative Lessons
Countries with strong public housing (Austria, Denmark, Finland) and regulated finance show more resilient affordability metrics. In contrast, liberal markets like the UK and US exhibit higher priceâtoâincome ratios and greater wealth concentration among owners. The brief emphasizes that policy choicesânot market inevitabilitiesâdetermine outcomes, offering a roadmap for panâEuropean sustainable housing strategies.
