Investor share slips to 27% of single-family purchases, Cotality says

Investors accounted for 27 percent of U.S. single‑family home purchases between March and June 2026, representing roughly 273,000 transactions, according to a September 3 analysis by Cotality. That share slipped from 28 percent at the end of the first quarter and marked a decline of about 40,000 purchases compared with the same period in 2025. The drop was driven primarily by “mega investors”—firms that own at least 1,000 properties—who contributed roughly 10,000 fewer deals, a notable contraction given their modest overall market presence. Thom Malone, principal economist at Cotality, highlighted that the decline coincided with the introduction of the 21st Century Road to Housing Act, which imposes a 350‑home ownership threshold for institutional owners, suggesting the legislation had an immediate chilling effect on large‑scale investors.

The broader consequence of the slowdown reflects both seasonal buying patterns and policy‑driven market shifts. While owner‑occupant activity typically rises in summer, investor volume remained above 2010s levels, when investors comprised less than 20 percent of purchases. Nonetheless, mega investors saw a 40 percent year‑over‑year drop in monthly acquisitions, falling to about 4,500 purchases per month in the first half of 2026. Large investors (100‑999 homes) cut their activity by 21 percent, medium investors (10‑99 homes) by 17 percent, and small investors (three‑nine homes) by only 3 percent. Malone noted that the sharp decline began in January, when the legislation was first introduced, creating a “real sharp discontinuity” that points to regulatory impact rather than broader market forces, a pattern only previously observed during the 2022 iBuyer exit.

Looking ahead, the third quarter will reveal whether the retreat of large investors is temporary or more lasting. Malone expects a modest rebound but not to pre‑legislation levels, and he anticipates that some institutional capital may shift toward built‑to‑rent projects, which are exempt from the new ownership caps. Smaller investors have shown a slight uptick as larger players pull back, though their activity has since moderated in line with normal seasonal trends. Cotality’s data indicate no detectable effect on home prices or rents in cities where investor activity fell, though localized impacts could emerge later given the lower transaction volume at the neighborhood level.
