Why Millions Of Americans Are Stuck In Expensive Homes While Vacancies Soar

The U.S. housing market is experiencing a crisis of affordability and stagnant mobility, according to Harvard University’s Joint Center for Housing Studies 2026 State of the Nation’s Housing report released June 17, 2026. Data shows a record low relocation rate of 11.2% in 2024 as households face surging insurance and tax costs.

Homeowners are facing a steep increase in non-mortgage expenses. Between 2019 and 2025, average national property taxes rose 31% and average monthly insurance premiums increased 72%, the report stated.

These costs, combined with stubbornly high mortgage rates driven by inflation, have locked many residents into their current homes. The report noted that first-time buyers are particularly strained when attempting to secure down payments.

Why are rental costs impacting low-income households?

Approximately 50% of renter households were cost-burdened in 2024, meaning they spent at least 30% of their income on housing, according to the Harvard report. Twenty-six percent of those renters were severely cost-burdened, spending more than half of their income on housing.

The burden falls most heavily on the lowest earners. The report found that 83% of renters earning less than $30,000 are cost-burdened.

This financial pressure is widening racial homeownership gaps. The report stated that access to affordable housing disproportionately impacts Black, Hispanic, and multiracial renters.

Why is housing inventory rising while affordability drops?

National unsold inventory reached 127,000 units in January 2026, the highest level since 2009. While vacancies are opening up, high construction costs make new builds too expensive for low- and moderate-income households.

The report highlighted a stark contrast in how different cities are experiencing this trend between 2021 and 2025:

• Austin: Apartment vacancy rates increased 5%, and active for-sale listings grew to more than three times previous levels, contributing to a 7% annual decrease in rents.
• Chicago: Apartment vacancy increased by only 0.5%, while for-sale listings fell by more than 20%.

Broader economic factors are further suppressing demand. The report cited a low-hire, low-fire job market and historic lows in consumer sentiment earlier in 2026 as reasons why people are avoiding major financial decisions like buying a home.

Population growth is also slowing. Net international migration halved in 2025, and the Census Bureau estimates it could fall another 75% in 2026, according to the report.

How are cities responding to federal funding gaps?

The report stated that federal spending cuts under the Trump administration have shifted the responsibility for producing low-cost units to state and local governments.

Some municipalities are implementing zoning reforms to increase supply. Minneapolis adopted a 2040 plan that eliminated single-family exclusive zoning to boost affordable housing. New York is pursuing a housing plan aimed at building 200,000 new homes.

Local governments are also using state Low-Income Housing Tax Credit programs and loosening land-use laws to encourage development.

The report emphasized that federal aid remains essential for the most deeply affordable units and for disaster recovery. In 2025, the U.S. experienced 23 billion-dollar climate-related events.

US faces interlocking housing crises — affordability, homelessness, climate change, and discrimination — that demand coordinated action across federal, state, local, private, and nonprofit actors.
