Economists warn slower household formation and rising inventory could reshape home prices, purchase demand, and mortgage origination opportunities over the next decade.
A new white paper from the Mortgage Bankers Association suggests that assumption may not hold true for much longer.
In its report, Implications of a Persistent Slowing in Housing Demand, MBA economists argue that demographic shifts, slower household formation, and continued housing construction could fundamentally alter the housing market's supply-demand balance over the next decade.
The report arrives as housing markets across many regions continue to adjust following the pandemic-era surge in demand fueled by historically low mortgage rates. While affordability challenges remain significant, MBA researchers say several long-term trends are beginning to weaken the foundations of housing demand.
According to the report, strong millennial household formation following the financial crisis helped drive demand far beyond the pace of new construction, contributing to rising home prices, higher rents, and estimates of a national housing shortage ranging from 1.5 million to 7.3 million units.
That imbalance intensified during the pandemic as low mortgage rates accelerated home purchases and builders responded by increasing construction activity, particularly in multifamily housing and across the South and West.
By 2025, however, housing markets in many areas began showing signs of rebalancing. Vacancy rates increased, rent growth slowed, and for-sale inventory expanded as newly constructed housing entered the market and demand cooled.
MBA Chief Economist Mike Fratantoni said understanding future housing demand requires looking beyond today's affordability challenges.
"Over the past several years, growth in housing demand has slowed as new housing supply has entered the market in many regions," Fratantoni said. "These findings can help industry participants and policymakers better prepare for future changes in housing and mortgage market dynamics."
The report points to several demographic headwinds expected to slow household formation in the coming decade, including an aging population, lower fertility rates, slower population growth, reduced immigration, and smaller generations following the Millennial cohort.
At the same time, researchers expect housing inventory to gradually increase as Baby Boomers transfer homes to younger generations.
MBA projects annual housing demand will average roughly 1.13 million units between 2025 and 2035 before eventually falling further. Meanwhile, housing supply could increase by as many as 10.6 million to 14.6 million units over the same period. If residential construction remains elevated, supply growth could outpace demand growth in some markets, placing downward pressure on home prices.
For mortgage professionals, the implications extend beyond housing inventory.
The report warns that slower housing demand growth could affect mortgage origination volumes, borrower equity accumulation, and credit performance. Markets that have relied on rapid home-price appreciation and inventory shortages may face a different operating environment than the one lenders and brokers have navigated for much of the past decade.
The findings do not suggest a nationwide housing glut is imminent. Rather, MBA researchers expect local market conditions to become increasingly important as demographic trends, migration patterns, and construction activity vary across regions.
Still, the report represents a notable shift in the industry's conversation. At a time when affordability concerns continue to dominate headlines, MBA is urging mortgage professionals to prepare for a future in which housing demand growth may no longer be the primary driver of market dynamics.
