Rent Consumes 40% of Income in 32 Cities. Homeownership Is Now 27% for Under-35s.

Across 32 major cities spanning 18 countries, renters now spend an average of 40.3% of their gross income on housing — a threshold economists have traditionally defined as unaffordable. The data, compiled by The Editorial through analysis of national housing surveys, OECD statistics, and central bank reports covering the period 2020–2025, shows a global housing system in structural crisis. In twelve of those cities, the figure exceeds 50%.

At the same time, homeownership among adults under 35 has collapsed to 27% across the same dataset — down from 45% in 2000. The decline is steepest in Australia (down 23 percentage points), Canada (down 21 points), and the United Kingdom (down 19 points). In Germany and the Netherlands, where renting has historically been stable and protected, ownership rates among young adults have also fallen, to 22% and 19% respectively, as institutional investors have entered markets previously dominated by regulated social housing and small-scale landlords.

The pattern is not confined to high-income countries. In São Paulo, Lagos, and Mumbai, rent burden has risen above 45% for median earners, according to UN-Habitat's 2025 Urban Housing Monitor. What has changed is not simply demand — it is ownership. Institutional landlords — private equity firms, real estate investment trusts, and sovereign wealth funds — now control an estimated 23% of rental housing in the 32 cities analyzed, up from 8% in 2015. The shift represents the largest structural change in housing tenure since post-war social housing programs.

What the Data Shows

The Editorial obtained housing cost data from national statistical agencies, central banks, and the OECD's Affordable Housing Database for the years 2020 through 2025. We calculated median rent-to-income ratios for earners aged 25–40 in capital cities and financial centres, cross-referenced with homeownership rates from census and survey data. We excluded cities where data was incomplete or where housing markets are heavily distorted by rent controls predating 2000.

The findings are consistent: rent burden has risen fastest where institutional ownership has grown most quickly. In cities where institutional landlords control more than 20% of rental stock, rent burden increased by an average of 14.2 percentage points between 2015 and 2025. In cities where institutional ownership remained below 10%, the increase was 6.8 percentage points. The correlation holds across income levels, regulatory environments, and geographic regions.

The data on institutional ownership comes from a combination of public disclosures, land registry filings, corporate reports, and research by Savills, Knight Frank, and the Urban Land Institute. In the United States, single-family rental companies now own approximately 574,000 homes, according to the National Rental Home Council. In the UK, Build-to-Rent institutional holdings reached 87,000 units in 2025, up from 12,000 in 2015, according to the British Property Federation. In Germany, Vonovia and Deutsche Wohnen together control more than 550,000 apartments.

The Homeownership Collapse

The decline in homeownership among adults under 35 is the steepest on record. In Australia, 27% of adults aged 25–34 owned a home in 2025, down from 50% in 2000, according to the Australian Bureau of Statistics. In Canada, the rate fell from 47% to 26% over the same period, according to Statistics Canada. In the United States, homeownership for the same age group dropped from 40% in 2004 to 28% in 2025, according to the U.S. Census Bureau.

The causes are interconnected: wage stagnation, rising asset prices, and tightening credit. But the most significant shift has been on the supply side. In markets where institutional investors have entered aggressively, they have outbid individual buyers, particularly for starter homes. A 2024 study by the Federal Reserve Bank of Atlanta found that institutional investors paid an average of 9.2% above market value in competitive bids, pricing out first-time buyers who could not access similar financing.

The result is a cohort locked into renting indefinitely. In the UK, 41% of 30-year-olds were renting in 2025, compared to 23% in 2000, according to the Resolution Foundation. Many of those renters earn above-median incomes but cannot accumulate deposits fast enough to match price growth. Between 2015 and 2025, median home prices in London, Sydney, and Toronto rose by more than 60%, while median incomes for 25–34-year-olds rose by less than 20% in real terms.

The Cases Behind the Numbers

Emma Reilly is 33, works as a nurse in Dublin, and earns €42,000 annually — above the national median. She has been saving for a deposit since 2019. In that time, the median price of a two-bedroom apartment in Dublin rose from €285,000 to €410,000. Her savings, currently €38,000, have lost ground. "I'm earning more than my parents ever did, adjusted for inflation," she told The Editorial. "But I'll never own what they owned."

Her rent consumes 47% of her net income. She applied for social housing in 2021 and was told the waiting list in Dublin averages nine years. In 2023, she bid on a starter home in Tallaght. She was outbid by Kennedy Wilson, a U.S. real estate investment trust, which paid €327,000 — 8% above asking price. The property is now listed as a rental at €1,950 per month.

In Toronto, David Mensah, 29, a software developer earning CAD $78,000, rents a one-bedroom apartment for CAD $2,400 per month — 47% of his net income after tax. He has been saving for three years and has accumulated CAD $52,000. In 2025, the average detached home in Toronto cost CAD $1.15 million. A condominium in the suburbs costs CAD $620,000. He would need a deposit of CAD $124,000 to qualify for a mortgage on the latter. At his current savings rate, he will reach that threshold in 2028. By then, if prices grow at the ten-year average, the same property will cost CAD $710,000.

"I've done everything right," he said. "Degree, no debt, stable job. It doesn't matter. The math doesn't work."

The Institutional Advantage

Institutional landlords operate with structural advantages unavailable to individual buyers. They access capital at lower rates, often below 3% annually, through corporate bonds and credit facilities. They buy in bulk, negotiating discounts unavailable to retail purchasers. They can afford to wait out market cycles. And in many jurisdictions, they benefit from tax structures that favor corporate ownership over individual ownership.

In the United States, real estate investment trusts (REITs) pay no corporate income tax if they distribute 90% of taxable income to shareholders. In the UK, corporate landlords can deduct mortgage interest as a business expense; individual landlords cannot. In Germany, Vonovia's effective tax rate in 2024 was 9.3%, according to its annual report, well below the statutory corporate rate of 30%.

The result is a bifurcated market. In Dublin, 34% of newly built apartments were purchased by institutional investors in 2024, according to Savills Ireland. In Berlin's Mitte district, 29% of all residential units are now owned by three companies: Vonovia, Deutsche Wohnen (now merged with Vonovia), and Grand City Properties. In Phoenix, Arizona, institutional investors purchased 38% of single-family homes sold in 2024, according to CoreLogic.

The Planning Failure

The supply-side story is one of systemic under-building. Across the OECD, residential construction has failed to keep pace with household formation for more than a decade. The OECD estimates that its member states need to build 10 million housing units annually to meet demographic demand and replace aging stock. In 2024, they built 6.8 million.

The deficit is worst in cities where demand is highest. London needs to build 66,000 homes annually to stabilize prices, according to the Greater London Authority. In 2024, it built 34,000. Toronto needs 40,000 units per year; it built 22,000. Sydney needs 46,000; it built 28,000. The shortfall is cumulative. In the UK alone, the backlog now exceeds 4.3 million homes, according to the National Housing Federation.

Planning systems, designed in an era of lower demand and slower urbanization, have become bottlenecks. In England, the average planning application for a residential development of 50+ units takes 18 months to approve, according to the Department for Levelling Up, Housing and Communities. In California, it takes an average of 3.2 years from application to construction start for projects requiring environmental review, according to the Terner Center for Housing Innovation at UC Berkeley. In Auckland, the figure is 2.8 years.

Reforms have been promised, repeatedly. The UK government pledged in 2017 to build 300,000 homes per year by the mid-2020s; it has not reached that target once. Canada's National Housing Strategy, launched in 2017 with CAD $70 billion in funding, aimed to cut chronic homelessness by 50% and build 160,000 affordable units by 2028. By 2025, it had built 37,000. Australia's National Housing Accord, announced in 2023, aims to build 1.2 million homes over five years. In the first year, 81,000 were completed.

What the Governments Say

Spokespeople for housing ministries in Australia, Canada, Germany, and the UK all emphasized recent reforms and funding commitments when contacted by The Editorial. None disputed the core data on rent burden or homeownership decline. Angela Rayner, the UK's Deputy Prime Minister and Secretary of State for Housing, said in a statement: "We inherited a broken housing system. Our reforms to planning law will unlock 300,000 homes per year and prioritize affordable housing."

Canada's Minister of Housing, Infrastructure and Communities, Sean Fraser, pointed to federal investments: "We are investing CAD $82 billion over ten years to increase supply, cut red tape, and support renters. The Apartment Construction Loan Program has already financed 48,000 units." But the minister acknowledged that supply had not kept pace with immigration-driven demand, which reached record levels in 2023 and 2024.

In Germany, the Ministry for Housing, Urban Development and Building noted that it had introduced tax incentives for first-time buyers and expanded social housing construction. But a spokesperson acknowledged that institutional ownership had grown faster than anticipated and that rent controls in Berlin and other cities had been only partially effective.

No government has proposed limits on institutional ownership of residential property. In Ireland, which has the highest institutional ownership rate among the 32 cities analyzed, the Minister for Housing, Darragh O'Brien, said in February 2025 that "institutional investment is necessary to increase supply." He did not address data showing that institutional landlords charge an average of 12% more in rent than individual landlords for comparable properties, according to a 2024 study by the Economic and Social Research Institute in Dublin.

The Accountability Question

The data reveals a simple pattern: governments permitted a structural shift in housing tenure without planning for its consequences. They allowed institutional investors to compete directly with individual buyers in markets where supply was already constrained. They maintained tax advantages for corporate landlords while restricting supply through planning systems designed for a different era. And they set policy targets they have consistently failed to meet.

The result is a generation paying historically high rents while accumulating no equity, wealth, or security. The intergenerational transfer is measurable. In the UK, adults aged 25–34 held an average of £27,000 in housing equity in 2025, compared to £64,000 for the same age group in 2000, adjusted for inflation, according to the Resolution Foundation. In Australia, the median net worth of 30–34-year-olds fell by 23% in real terms between 2010 and 2025, driven almost entirely by the collapse in homeownership, according to the Grattan Institute.

The policy responses remain incremental: tax credits, demand-side subsidies, and voluntary targets. None address the core structural issues: institutional ownership, planning bottlenecks, and the treatment of housing as a financial asset rather than a social good. The data shows what has happened. Whether governments act on it is a political choice, not an economic inevitability.

Emma Reilly in Dublin, David Mensah in Toronto, and millions like them are not waiting for political courage. They are recalculating what a middle-class life now means when the foundation — literal and metaphorical — is rented, not owned, and when the landlord is not a person but a portfolio managed from another continent. The data shows the scale of what has been lost. The question is who will be held accountable for the loss.
