The Decadelong Shortage Narrative Faces a Major Reality Check
For more than ten years, the defining headline of the American real estate market has been a chronic, frustrating shortage of homes. A groundbreaking white paper published by the Mortgage Bankers Association (MBA), titled “Implications of a Persistent Slowing in Housing Demand,” suggests this long-held narrative may soon turn entirely on its head.
According to the MBA’s projections, a perfect storm of slowing household formation and steady construction could trigger a housing surplus in various parts of the country as early as 2035.
The Demographics Drought: Why Housing Demand is Shrinking
The projected shift from a seller’s market to a buyer’s market is not primarily driven by builders over-constructing, but rather by a rapidly shrinking pool of future buyers. The MBA outlines four converging demographic headwinds that are drying up the housing demand pipeline:
-
An Aging Population: As the massive Baby Boomer generation continues to age, existing homes will gradually be transferred to younger generations, naturally supplementing available inventory.
-
Declining Fertility Rates: Fewer children mean smaller future household sizes and delayed or altogether bypassed household formations.
-
Smaller Generational Cohorts: Gen Z represents a notably smaller population group than the preceding Millennial generation, which drove the massive post-financial-crisis home-buying wave.
-
Slowing Immigration: Recent policy adjustments have curbed the flow of immigration, with some forecasts projecting net immigration could even skew negative for brief periods in the coming years.
Reflecting these headwinds, the Congressional Budget Office (CBO) adjusted its 2035 population forecast down to 357.3 million—a drop of 6.8 million people compared to estimates released just a year prior.
Supply vs. Demand: Analyzing the 10-Year Outlook (2025–2035)
To understand the potential tipping point in 2035, the MBA mapped estimated housing demand against three potential construction speed scenarios over the next decade.
First, the Projected Demand Baseline is estimated at 11.34 million units total, requiring an average annual building pace of roughly 1.13 million units per year to keep up.
Against this demand, the MBA outlines three supply pathways:
-
Conservative Supply Scenario: Yields 10.57 million units (approximately 1.06 million units per year), which would keep the housing market relatively tight.
-
Moderate (Mid) Supply Scenario: Yields 12.65 million units (approximately 1.26 million units per year), starting to outpace demand.
-
Optimistic (High) Supply Scenario: Yields 14.56 million units (approximately 1.46 million units per year), introducing a substantial buffer of inventory.
The Surplus Pivot: If construction speeds track at a moderate or optimistic pace, the cumulative net housing supply could surpass total demand by 1.3 million to 3.2 million units by 2035, effectively ending the undersupply crisis and placing downward pressure on home prices.
Market Skepticism and the “Self-Correcting” Real Estate Cycle
While the data points to a potential macro-shift, some industry experts advise caution before anticipating a widespread pricing crash.
Joel Berner, Senior Economist at Realtor.com, points out that real estate operates as a dynamic, self-correcting ecosystem. If buyer demand weakens significantly, homebuilders are highly likely to hit the brakes on new housing starts to preserve profit margins.
Conversely, should home prices begin to drop, it would instantly unlock demand from sidelined, rent-weary households who have been waiting for affordability to return.
In fact, homebuilders are already adjusting to current conditions. With new construction inventory sitting at a relatively high 10.3 months of supply, total housing starts fell 15.4% in recent month-over-month data, led by a sharp contraction in multifamily builds and a modest decline in single-family starts.
A Tale of Two Markets: Metropolitan vs. Suburban
Crucially, both the MBA and local analysts emphasize that a housing surplus will not be felt equally nationwide.
New construction continues to concentrate heavily in the Sun Belt, South, and West, where vacant land is plentiful and local zoning regulations permit rapid building. These regions are the most vulnerable to localized oversupply and softening prices.
Meanwhile, high-demand coastal metropolitan areas and traditional northern metros face persistent land scarcity and stringent permitting laws. In these dense urban centers, a true housing surplus remains highly unlikely, meaning localized price trends will continue to diverge widely.
