Why Trump’s Investor Ban Won’t Lower U.S. Home Prices
President Trump recently announced plans to ban large institutional investors from buying single-family homes, with the goal of boosting housing affordability and helping more Americans become homeowners. However, experts and housing data show that such a ban would likely have only a marginal impact on home prices — because the real driver of high housing costs is a chronic shortage of housing supply, not institutional ownership itself.
Institutional Investors Own a Small Portion of U.S. Housing
While large corporate investors often dominate headlines, the reality is that institutional investors own only a tiny fraction of the nation’s housing stock. According to recent research, institutional investors — defined as those owning 100+ homes — hold roughly 1% of all single-family homes in the United States.
Even when expanding the definition to include slightly smaller investor portfolios, the proportion of homes held by institutional entities is still very small compared to owner-occupants: more than 90% of investor-owned homes are held by individual or “mom-and-pop” landlords with fewer than 11 properties.
In practical terms, the vast majority of U.S. homeowners are traditional owner-occupants, and institutional buyers only represent a sliver of total housing ownership — meaning that policy targeting this tiny subset won’t substantially alter the overall supply available to buyers.
Underbuilding Since the Great Recession Has Created a Massive Shortage
The key reason housing prices remain high is not because Wall Street is hoarding homes — it’s because America has not built enough homes to keep up with demand for more than a decade.
Estimates from research institutions and the Census Bureau show the U.S. housing market is short millions of homes. For example:
-
Zillow and the U.S. Chamber of Commerce estimate the housing shortage at around 4.5 to nearly 4.7 million homes — meaning there are millions more households looking for homes than there are houses available.
-
Other analyses suggest the housing deficit could be in the range of 3.8 to nearly 5 million units when comparing current supply to historical norms and household formation patterns.
This shortfall largely stems from the collapse in homebuilding that followed the Great Recession (2007–2009). After housing starts plummeted during the financial crisis, construction never rebounded fully to meet the pace of household growth. Even with recent increases in building, the backlog remains significant and continues to put upward pressure on prices.
Why Supply — Not Institutional Buying — Drives Prices
Economics 101 teaches that prices are driven by supply and demand. In the U.S. housing market today:
-
Demand remains strong as population growth, household formation, and demographic trends keep more people seeking homes.
-
Supply remains constrained, with far too few homes being built or listed for sale relative to the number of prospective buyers.
Because the core imbalance is a lack of housing stock, even if institutional buyers were completely barred from the market, the inventory problem would persist. With too few homes available overall, prices would likely remain high as long as supply remains insufficient — regardless of who owns the existing homes.
Conclusion: Fixing Supply Is the Long-Term Solution
Targeting large investors can be politically attractive and may feel like a way to “level the playing field,” but data shows it won’t meaningfully reduce home prices if housing supply issues aren’t addressed first. A sustainable path to affordability must focus on increasing housing inventory, through strategies such as easing zoning and permitting, incentivizing construction, and addressing long-term underbuilding — because until we close the multi-million unit housing gap, prices will remain pressured by basic supply shortfalls.
