Finding a house to buy isn’t getting any easier.
The shortage of housing inventory got worse in 2025, according to Realtor.com, which found that the market needs 4 million more homes to meet buyer demand.
The inventory gap edged higher because the 1.36 million housing construction starts in 2025 fell 50,000 short of the number of households formed during the year. That extended an inventory shortfall that has persisted for a decade.
Why This Matters to You
A persistent lack of supply keeps home prices elevated, fueling overall inflation and complicating the Federal Reserve’s path on interest rates. High housing costs also crowd out other consumer spending, limiting discretionary purchases and weighing on the broader economy.
“Even when annual construction and household formation are roughly balanced, the market is still digging out from more than a decade of underbuilding,” said Danielle Hale, chief economist at Realtor.com, in a prepared statement. “Without a sustained and targeted increase in housing supply, particularly in areas with strong job growth and persistent demand, affordability challenges will continue to sideline many would-be buyers.”
Severe Inventory Shortage in the South
The shortage of homes for sale is one of the main causes behind the affordability crunch in the housing market. With a limited number of homes to choose from, buyers have fewer options, while sellers are able to keep their listing prices higher.
The National Association of Realtors (NAR) has also reported a shortage of homes for sale, which has driven the median existing-home sales price up to $396,800.
“Due to low supply, the median home price reached a new high for the month of January,” said NAR Chief Economist Lawrence Yun in a statement.
Last year’s housing inventory deficit is the third-largest since 2012, extending a trend that began when builders shied away from new home construction in the wake of the 2008 housing crisis.
The housing shortage last year was most severe in the South, where an additional 1.62 million homes are needed to meet demand, the Realtor.com report noted. But while the deficit was greatest in the South, the report noted that the Northeast has been struggling with a housing shortage for the longest, even as it was the only region to show improvement in 2025.
Construction Levels Decline
Realtor.com reported that builders completed around 1.5 million homes in 2025, down from 2024 levels but still above the historical average. Still, the pace of building wasn’t fast enough to make up the deficit, as the report found that it would take approximately seven years to close the inventory gap.
“While construction levels remain elevated compared with historical norms, they are not yet high enough, or targeted enough, to meaningfully close the gap,” said Hannah Jones, senior economic research analyst at Realtor.com.
The report also examined the pent-up demand among 18- to 44-year-olds and noted that 1.8 million households failed to form last year due to affordability issues. Realtor.com calculated these levels by looking at household formation ratios from the five-year period preceding the current housing shortfall.
“Rather than establishing independent households, many young adults have remained with parents, lived with extended family, or shared housing with roommates,” the report noted.
Additionally, the median income needed to afford a home improved to $86,000 in 2025, but it was still above the earnings of many young people, Realtor.com found.
