On October 22, 2026, the U.S. Treasury Department proposed the first rules for a new federal limit on large investors buying houses. Starting January 7, 2027, an investor that controls 350 or more single-family homes generally may not buy another one unless an exception applies. The limit comes from the 21st Century ROAD to Housing Act, which became law on July 11, 2026.
Few places have more at stake than Jacksonville. When the Government Accountability Office studied six metro areas this year, it found that institutional investors owned 22% of the single-family rental homes in the Jacksonville metro by 2024, the highest share of any metro in the study (GAO, March 24, 2026). So the question we hear from Northeast Florida sellers, buyers and small landlords is a practical one: does this change what my home sells for, what I compete against, or what I can buy?
Below is what the law and the proposed rules actually say, what they do not do, and a look at our own county numbers that explains why the big funds had already slowed their resale buying long before the law passed.
The short answer
- Who is covered: for-profit entities in the single-family rental business with investment control over at least 350 single-family homes. Individuals and small landlords are not covered.
- What changes: from January 7, 2027, covered investors generally cannot buy more single-family homes, with exceptions for build-to-rent, qualifying renovate-to-rent and certain renter-to-buyer programs.
- What does not change: no investor is required to sell homes it already owns, so there is no forced wave of listings.
- What is still open: Treasury’s rules are proposed, not final. Comments are due November 23, 2026, and later phases will cover reporting and enforcement.
What the law does
Section 1001 of the ROAD to Housing Act is short on its face. According to a July 15, 2026 summary by the law firm Mayer Brown, the key pieces are these:
- The 350-home test. A large institutional investor is an entity in the business of investing in or managing single-family homes that, after enactment, holds investment control over at least 350 of them, alone or with others. Control includes owning more than 25% of the entity that owns the homes, unless the owner is a passive investor.
- What a single-family home is. A structure with two or fewer units intended for one household. Manufactured homes are excluded.
- The start date. The limit takes effect 180 days after enactment, which is January 7, 2027, the date Treasury uses.
- The exceptions. They include newly built, renovated or converted homes held for sale; build-to-rent and renovate-to-rent programs; rent-to-own and other homeownership programs that meet set terms; repossessions and foreclosure-related purchases by lenders and servicers; purchases from another covered investor of homes it already held lawfully; purchases from non-covered investors within two years of the effective date; and communities for households with a member 55 or older.
- No forced sales. An earlier draft would have made large investors sell certain homes to individual buyers over seven years. That requirement is not in the final law.
- Penalties and sunset. A violation can cost the greater of $1 million or three times the purchase price. The limit is set to expire after 15 years.
What Treasury proposed on October 22
Treasury calls this proposal the first of several rulemakings. Based on Treasury’s announcement and summaries published by the National Association of REALTORS® and Legis1, the proposal fills in how the exceptions work:
- Build-to-rent: limited to newly built homes that have never been owner-occupied and are bought within 18 months of completion.
- Renovate-to-rent: limited to homes that fail key building-code standards when bought. The investor must fix those problems and spend at least 15% of the purchase price on improvements, with a safe harbor when at least 10% goes to structural or core systems. Paint, flooring and appliances do not count toward the threshold.
- Renter-to-buyer programs: must include free positive rent reporting to the credit bureaus and meaningful financial help toward a purchase. The proposal sets a safe harbor of up to $5,000 for renters of five years or more, and some program contracts carry a right of first refusal with a 30-day first look before the home is marketed to anyone else.
- Written programs only: an investor must have adopted the program in writing before it buys. Relabeling a purchase after the fact does not qualify.
- Anti-layering: a passive-investor test keeps funds from splitting holdings across entities to stay under 350.
The comment docket is TREAS-DO-2026-0529 on regulations.gov, with comments due November 23, 2026 (Legis1). Treasury itself says reliable data are not yet available on how many entities the limit will touch (Legis1).
Why Jacksonville is the Florida market to watch
GAO’s March 2026 report followed six metro areas from 2018 through 2024: Cincinnati, Dallas, Jacksonville, Nashville, Phoenix and Seattle. Institutional investors owned between 4% (Seattle) and 22% (Jacksonville) of single-family rental homes, but only about 1% to 3% of all single-family homes in those areas. Their fastest growth came in 2021 to 2023 and slowed in 2024, and in no year in any of the six metros did they sell more than 8% of their holdings.
Two cautions on that 22% figure. First, GAO defined an institutional investor as an owner of 5,000 or more homes nationwide, which is a much stricter test than the law’s 350, so the law reaches more owners than GAO counted. Second, it is a share of rental homes, not of all homes. Most single-family homes in Northeast Florida are still owner-occupied, and that is the market most sellers are actually competing in.
Our numbers: at today’s rates, a typical Florida rental does not cash-flow
The bigger reason large funds stepped back from buying resale homes is arithmetic. We ran every Florida county through our investment property calculator at its typical home value and typical rent, with 25% down, a 30-year loan at 7.32% (the Freddie Mac average for the week of October 22, 2026), 5% vacancy, maintenance at 8% of rent, the county’s average Citizens insurance premium, and non-homestead property tax at FY2025-26 millage. Here is what a typical home looks like as a rental:
| County | Typical value | Typical rent | Est. cap rate | Cash flow/mo |
|---|---|---|---|---|
| Duval | $294K | $1,603 | 3.46% | −$668 |
| Clay | $335K | $1,805 | 3.76% | −$677 |
| St. Johns | $493K | $2,020 | 2.65% | −$1,451 |
| Nassau | $485K | $2,144 | 3.05% | −$1,266 |
| Baker | $314K | $1,850 | 4.34% | −$482 |
| Hillsborough | $376K | $1,978 | 3.44% | −$857 |
| Orange | $401K | $1,933 | 3.01% | −$1,059 |
| Polk | $296K | $1,814 | 4.14% | −$504 |
| Pasco | $328K | $1,985 | 4.19% | −$544 |
| Pinellas | $369K | $2,028 | 3.28% | −$892 |
| Marion | $268K | $1,593 | 4.53% | −$369 |
| Lee | $334K | $1,827 | 3.45% | −$762 |
| Broward | $422K | $2,457 | 3.72% | −$867 |
| Palm Beach | $476K | $2,673 | 3.63% | −$1,014 |
| Miami-Dade | $523K | $2,789 | 3.44% | −$1,194 |
On those settings, none of Florida’s 67 counties cash-flows at a typical home. The highest estimated cap rate among counties with a Zillow rent index is Jackson County in the Panhandle at 4.86%, still well under a 7.32% mortgage rate. In Duval, a typical rental would need about 59% down, or a loan rate near 2.3% at 25% down, just to reach zero monthly cash flow. Drop the rate to 3% and 16 of the 67 county figures turn positive, which is roughly the world the funds were buying in before 2022.
That is negative leverage: when a property earns less on its price than the loan costs, every borrowed dollar makes the return worse. Large funds may borrow on better terms than an individual or pay cash, but the same math explains GAO’s finding that their growth slowed in 2024. In other words, the law is landing on a buyer group that had already pulled back from resale homes, while leaving open the build-to-rent channel for newly built homes.
These are county-wide estimates for comparison, not the return on any specific property. A home bought below the typical value, or rented above the typical rent, can look very different. You can rerun the county table on your own down payment and rate in the calculator, or see the counties ranked by cap rate.
What it means if you are selling a home in Northeast Florida
For most sellers, very little changes. Large funds were a small slice of buyers on resale homes even at their peak, and our numbers suggest they were not paying up for typical resale houses at today’s rates anyway. A few specifics:
- Some houses may see one fewer cash bidder. If your home is the kind of single-family house a rental fund might have bid on, plan on an owner-occupant or smaller investor as your likeliest buyer, with financing contingencies to match.
- Homes that need major work still have a big-investor path. The renovate-to-rent exception lets a covered investor buy a home that fails building-code standards if it invests at least 15% of the price in real repairs.
- Do not expect a flood of competing listings. Nothing forces investors to sell, and GAO found they sold under 8% of holdings a year.
- Local conditions still set your price. In Duval, 29% of listings had a price cut and the typical home took about 61 days to go under contract, based on Zillow data through September 2026 in our Florida housing tracker.

What it means if you are buying
First-time buyers are the group the law is aimed at, and the change is real but modest. Starting January 7, 2027, a fund with 350 or more homes cannot outbid you with cash on a resale single-family home unless it fits an exception. You will still compete with smaller investors, second-home buyers and other owner-occupants, and new construction can still be sold to build-to-rent programs.
A separate federal change lands the same week. The Federal Housing Administration will accept VantageScore 4.0 and FICO Score 10T alongside classic FICO starting January 1, 2027, models that can count rent and other bill-payment history (Florida REALTORS®, October 19, 2026). Combined with the rent-reporting requirement in the investor programs, renters with steady payment records may find qualifying a little easier in 2027.

What it means if you rent from a large landlord
The law does not change existing leases. What may change is what your landlord offers. A covered investor that wants to keep buying under the homeownership exceptions must run written programs that report your on-time rent to the credit bureaus at no charge and provide real financial help toward buying, and some of those contracts give you a 30-day first look before the home is marketed to anyone else. If your landlord announces such a program in 2027, read the terms closely: the help, the price formula and how long you have to decide all matter.
What it means for small investors
If you own fewer than 350 homes, you are not covered. In theory, less competition from large funds helps small investors on resale homes. In practice, the math in the table above is the bigger constraint at today’s rates. Underwrite every purchase on the actual price, rent, insurance quote and tax bill rather than a rule of thumb, and remember that the first-year tax bill on a non-homestead purchase is based on the new market value. If you buy new construction to rent, the builder incentive calculator and our look at Jacksonville new construction by county show where builders are discounting. Nothing here is tax, legal or investment advice.
What to watch next
- November 23, 2026: comment deadline on Treasury’s proposal (docket TREAS-DO-2026-0529).
- January 7, 2027: the purchase limit takes effect, whether or not the rules are final.
- Later phases: Treasury has said further rules will cover more exceptions, reporting, recordkeeping and enforcement. How it handles the build-to-rent exception will matter most in fast-growing Florida counties.
Frequently asked questions
When does the ban on large investors buying homes start?
January 7, 2027. The 21st Century ROAD to Housing Act became law on July 11, 2026, and its purchase limit takes effect 180 days later. Treasury proposed its first implementing rules on October 22, 2026; comments are due November 23, 2026, and the rules could change before they are final.
Who counts as a large institutional investor under the 2027 rule?
A for-profit entity in the business of owning, renting or managing single-family homes that has investment control, alone or with others, over at least 350 single-family homes. A single-family home here means a structure with two or fewer units for one household; manufactured homes are excluded. Individuals and small landlords below 350 homes are not covered.
Do big investors have to sell the Florida homes they already own?
No. The enacted law does not require large investors to sell homes they owned before it took effect. An earlier version would have required sales to individual buyers over seven years, but that provision is not in the final law, according to a Mayer Brown summary of July 15, 2026.
Can large investors still buy new construction in Florida?
Yes, under the build-to-rent exception. In Treasury's October 22, 2026 proposal, that exception covers newly built homes that have never been owner-occupied and are bought within 18 months of completion, under a written program adopted before the purchase.
How many Jacksonville rental homes do institutional investors own?
The U.S. Government Accountability Office reported on March 24, 2026 that institutional investors owned 22% of single-family rental homes in the Jacksonville metro area by 2024, the highest share of the six metros it studied. GAO counted owners of 5,000 or more homes nationwide, a stricter test than the law's 350 homes.
Will the investor ban lower Florida home prices?
Probably not by much on its own. Large investors were a small share of all single-family owners in the metros GAO studied, from under 1% to 3%, and they are not required to sell. Prices will still be set mainly by local supply, mortgage rates, insurance and taxes. The likelier effect is fewer large cash bidders on resale homes in the price ranges funds used to target.
The takeaway
The 2027 limit on large investors is a real change in who may buy single-family homes, and Jacksonville, where institutional investors own about one in five single-family rentals, is one of the places it touches most. But it does not force any sales, it leaves new construction open through build-to-rent, and it arrives after high mortgage rates had already pushed typical Florida rentals into negative cash flow. For most sellers and buyers in Northeast Florida, local supply, rates, insurance and taxes will still matter more to price than this law. Watch the final rules, and if you are buying or selling in the next few months, price against what is actually selling near you.
