There is a growing belief that large institutional investors are buying up single-family homes and driving the U.S. housing affordability crisis. While emotionally compelling, the data does not support this narrative.

Institutional investors own roughly 0.5% of U.S. single-family homes, and institutional purchases of single-family rentals have declined by more than 90% since 2022. These firms act as opportunistic buyers, not market-wide price setters.

The primary driver of housing affordability remains supply constraints. The U.S. is building fewer homes today than in 1959, despite having approximately double the population. Local zoning restrictions, regulatory hurdles, construction costs, and elevated mortgage rates continue to limit new housing supply.

Research highlighted by Jay Parsons shows that small, local investors still control more than 90% of the single-family rental market, and institutional ownership has largely come from transactions between landlords rather than displacement of owner-occupants.

Addressing housing affordability requires confronting supply realities — not oversimplifying the problem by blaming institutions.
