Treasury has proposed a rule that would bar any company controlling 350 or more single-family homes from buying another one, starting January 7, 2027. It is a proposal only. Treasury announced it on October 22, and it is not in force. The public has 30 days after the Federal Register notice to comment before any final version is written.
What Treasury put out for comment
The notice of proposed rulemaking, titled “Restrictions on Large Institutional Investor Purchases of Single-Family Homes,” was scheduled to run in the Federal Register on October 23. It carries out Section 1001 of the 21st Century ROAD to Housing Act. Congress passed that law, and it became law on July 11, 2026 without a presidential signature.
The January 7, 2027 date comes from that statute, which starts the ban 180 days after enactment. Treasury’s proposal would spell out the terms, exceptions and penalties. It also follows Executive Order 14376, signed January 20, 2026, which says people “live in homes, not corporations.”
For homeowners and would-be buyers, the question is whether this changes who they compete with and what nearby houses sell for. The proposal sets no prices. It only says which large buyers could purchase single-family homes after the start date, and which could not.

Who counts as a large investor
Treasury’s announcement says a large institutional investor is, in part, an entity with direct or indirect investment control over at least 350 single-family homes. Law firm summaries of the statute say control can be shared with others and that the count is a total across all the entity’s homes.
Control can mean owning the home, running the fund that owns it, managing it, or holding more than 25 percent of the owner, unless the holder is a passive investor. The proposal would define a passive investor as one that shares no directors or officers with the owner of the home and has no property control rights. It would also define what it means to be “in the business of” investing in or managing single-family homes.
Purchases that would still be allowed
The law lets large investors make “excepted purchases.” The proposal adds detail, including safe harbors, which are tests that would count as meeting a rule:
- Build-to-rent: homes never lived in by an owner, bought within 18 months of receiving a certificate of occupancy, then rented first.
- Renovate-to-rent: run-down homes brought up to code, with improvements of at least 15 percent of the purchase price. A 10 percent safe harbor applies to work on structural or core systems.
- Homeownership programs: renters given a path to buy, such as financial support of the lesser of $5,000 or 2.5 percent of the price after five years of renting, or 3.5 percent after seven years.
- Other cases: debt satisfaction, loss mitigation, and purchases from another large investor.
The statute also exempts homes in 55-plus communities, according to Mayer Brown, a law firm that tracked the bill.
Penalties and homes already owned
Under the law, a prohibited purchase would carry a civil penalty of up to the greater of $1 million or three times the purchase price. The proposal would treat one purchase involving several large investors as a single violation when the maximum penalty is figured. Allen Matkins, another law firm, reports that the penalty money would go to the Department of Housing and Urban Development (HUD) to expand homeownership.
The ban would not force anyone to sell. Mayer Brown notes that large investors need not sell homes they bought before the law passed, and that an earlier forced-sale requirement was dropped. The ban would also end automatically 15 years after it starts.
Treasury cannot change the 350-home threshold or add new categories of investors. Mayer Brown says the law lets the Treasury Secretary write rules after consulting the HUD Secretary and the chair of the Securities and Exchange Commission, but those rules cannot narrow the excepted purchases. That limits how far the final version can move from the proposal. Comments are more likely to shape the definitions and safe harbors than the 350-home line.
How to send a comment
Treasury prefers comments filed at Regulations.gov under docket TREAS-DO-2026-0529. Comments can also be mailed to the Treasury Department’s Office of Capital Markets, 1500 Pennsylvania Avenue NW, Washington, DC 20220. William Hicks of the Office of Domestic Finance is the listed contact for questions, at 202-622-0148.
The comment window runs 30 days from Federal Register publication, which puts it in late November. Only after that would Treasury issue a final rule. Until then the proposed text can change.
Where this leaves homeowners
Treasury Secretary Scott Bessent said in the announcement that “Under President Trump, this Administration continues to restore the path to affordable homeownership.” He also said the department wants to add housing supply and limit large investors’ role without causing unnecessary disruption.
What a ban would do to prices in any one town is not stated in the proposal. Property taxes, insurance and repairs keep coming either way. Anyone worried about those bills can start with the Consumer Financial Protection Bureau’s homeowner guides or a HUD-approved housing counselor.
Planning ahead for what the house costs?
Whatever happens to investor buying, the bills on an owned home keep arriving: the tax bill, the insurance premium, the repairs. Homeowners on a fixed income who never review them tend to overpay quietly, year after year.
Cut Your House Costs lays out ten moves to spend less on the house and protect its value, including a lower home insurance bill by shopping and asking for every discount. It also puts home equity options compared, from a HELOC to a reverse mortgage, side by side, and ends with the home-cost audit worksheet.
