MBA Research Counters US National Housing Shortage Narrative

Demographics and Policy Start to Shift the Narrative

The US housing market may be entering a different phase, reports Globe St. New research from the Mortgage Bankers Association challenges the long-standing housing shortage narrative. MBA’s July analysis argues that slowing demand now shapes market fundamentals, and the old shortage story no longer matches current conditions. Long-term demographic trends are changing demand patterns, while years of heavy construction have reshaped supply dynamics. These shifts challenge assumptions that residential ownership guarantees strong returns and may force new underwriting approaches.

MBA data already shows cracks in the shortage thesis. Household formation should slow meaningfully over the next two decades. The US added households at an average pace of 1.13M annually from 2025 through 2035. MBA expects that figure to fall to 802,000 annually from 2035 through 2045. Meanwhile, years of aggressive construction expanded housing inventories nationwide, especially in multifamily housing. Together, these forces weaken broad national assumptions and point toward wider regional differences.

The End of a Singular Shortage Story

For years, the housing shortage thesis guided capital allocation decisions. Investors expected demand to outpace supply and preserve pricing power for the foreseeable future. MBA now argues that investors should rethink that assumption. The report cites aging demographics, low fertility, smaller younger generations, and weaker immigration trends as key factors behind slower demand growth.

MBA worked with Harvard’s Joint Center for Housing Studies on the analysis. Their research projects annual demand of 1.13M units through 2035 before falling to 802,000 units through 2045. Earlier projections estimated shortages between 1.5M and 7.3M units nationwide. MBA now considers those estimates outdated and no longer reflective of current market realities.

The Details

Supply trends tell a similar story for housing bulls. Pandemic-era conditions encouraged developers to accelerate construction activity across the country. Developers expanded both multifamily and single-family pipelines as prices surged. MBA estimates home prices climbed roughly 55% between 2020 and 2025, encouraging even more development activity.

Developers concentrated much of that construction in southern and western markets. Multifamily starts reached their highest levels since the 1970s in several regions. MBA expects housing stock to grow between 10.6M and 14.6M units by 2035, depending on completion trends. After accounting for vacancies, second homes, and removals, supply could still match or exceed demand. Older Baby Boomers may further increase inventory as housing returns to the market over time.

Regional Divergence Replaces National Trends

MBA data shows sharply different outcomes across regions. The Sun Belt now faces new supply pressures after years of attracting residents, investors, and developers. Vacancies are rising while rent growth loses momentum. MBA reports rental vacancy increased from 5.6% in 2022 to 7.3% in 2025. Austin stands out as a market where supply exceeded absorption, creating softer conditions.

For-sale inventories have also increased across parts of the South and West. Rent growth has largely stalled in some markets, highlighting growing weakness. Large single-family rental operators have already started shifting capital toward tighter, supply-constrained markets. The Northeast and Midwest tell a different story. Limited construction, restrictive zoning, and expensive permitting continue limiting new supply. As a result, pricing remains more resilient despite slower national growth. MBA expects these regional differences to widen over time.

Sun Belt investors may need to focus on affordability and migration trends. Others may favor supply-constrained legacy markets in the Northeast and Midwest. Market selection now matters far more than broad national exposure.

Why It Matters

MBA’s findings could reshape housing investment strategies. Timing now matters more than broad demographic assumptions. A large delivery wave continues entering the market just as demand growth slows. Many deals assumed strong rent growth and limited competition, particularly in high-growth metros. Those assumptions may no longer hold.

Concessions and longer lease-up periods already signal softer conditions in several markets. MBA encourages investors to stress-test underwriting assumptions and prepare for longer absorption periods. The implications extend beyond near-term cash flow projections. MBA argues that national housing narratives now carry less value than local market analysis.

The group expects national home price growth to slow over time. Arizona, Texas, and Florida face greater risks as development pipelines continue delivering units. Investors can no longer treat residential housing as a universal trade. This cycle demands greater selectivity and deeper market knowledge.

What’s Next

Future returns will depend on local market analysis rather than national themes. MBA believes successful investors will match locations with specific household trends and demand drivers. Capital may rotate away from oversupplied Sun Belt markets and toward supply-constrained regions. Investors will likely adopt lower rent growth assumptions and longer absorption timelines.

Those adjustments will matter most for projects completing after 2025. Slower household formation will collide with elevated supply levels across several markets. Local market knowledge will determine investment outcomes in this cycle. The old housing shortage playbook appears far less reliable than before.
