There's a housing model that's been quietly growing for years, one that gives renters a brand-new single-family home with a yard, no shared walls, and professional maintenance, without ever having to come up with a down payment.
It's called build-to-rent (BTR), and it has become a meaningful piece of America's housing supply puzzle. Now, federal legislation may be about to reshape it in ways that could have real consequences for renters, developers, and the broader housing market.
Build-to-rent is exactly what it sounds like: single-family homes that are purpose-built not for sale, but for long-term renting. You can read more about Build-to-Rent in our earlier article here.
The sector has grown dramatically. About 7% of new single-family houses hitting the market are now for rent, not sale, and more than 10 times as many build-to-rent homes were completed in the U.S. in 2024 as compared with a decade earlier. Yardi Matrix estimates that 47,000 BTR units were completed in 2025 in BTR communities of 50 units or more.
It's filling a real gap. And the demand isn't going anywhere. In 2024, the U.S. had about 800,000 fewer single-family houses for rent compared with a decade earlier, according to the National Association of Realtors.
On March 12, the U.S. Senate passed the 21st Century ROAD to Housing Act by a vote of 89-10. This is one of the most significant pieces of housing legislation to move through Congress in decades.
The bill includes more than 40 provisions aimed at increasing housing supply, reducing regulatory burdens, and modernizing federal housing programs. But the provision generating the most controversy has nothing to do with zoning reform or permitting. It has to do with who gets to own rental homes—and for how long.
The bill would prohibit large institutional investors, defined as entities that control 350 or more single-family homes, from buying additional single-family homes. Existing portfolios would not be affected.
There are some exemptions. The legislation allows purchases tied to qualified build-to-rent, rent-to-own, and renovate-to-rent programs. This means large investors could still build or acquire homes for rental use, but only under specific conditions.
One key requirement is that homes acquired through these exemptions must be sold to individual homebuyers within seven years. Renters would also receive a “first look” period and a right of first refusal before the property is sold. If investors fail to comply, penalties would be severe. Fines could reach up to $1 million per violation or three times the purchase price of the property, whichever is greater.
The problem, critics argue, is that a mandatory seven-year sell-off doesn't just restrict institutional buyers. It effectively dismantles the economics of build-to-rent entirely.
The issue is timing and cost. Investors would likely lose about five months of rent during each sale process due to vacancy, marketing, and closing delays. With typical monthly rent around 0.8 percent of home value, that translates to roughly 4 percent in lost revenue per property.
At scale, the impact could be significant. One estimate suggests that if build-to-rent activity fell by 60 percent, it could reduce new rental supply by about 72,000 homes per year, a drop of more than 7 percent of single-family home completions and 18 percent of rental completions.
These losses would be most felt in the middle market. Build-to-rent typically serves families who cannot afford to buy but can afford higher-quality single-family rentals, a segment already facing a housing shortage.
Yes, and in a notably bipartisan way. On April 22, 2026, 76 bipartisan members of the U.S. House of Representatives, led by the Co-Chairs of the Congressional Real Estate Caucus and the Build America Caucus, sent a letter to Speaker Mike Johnson and Minority Leader Hakeem Jeffries urging House leadership to strip or substantially revise the BTR-related restrictions in Section 901 of the Act.
The signatories warn that Section 901, as drafted, would have far-reaching, unintended consequences that run counter to the Act's stated goal of expanding housing opportunity.
