The quick read: Yes, inside a narrow window or under another exception. Under the build-to-rent exception in the Treasury Department's proposed rule, published in the Federal Register on October 23, 2026, a large institutional investor can buy a home only if the home was never owner-occupied, is bought within 18 months of its certificate of occupancy and is first occupied by renters after the purchase. The purchase ban in the 21st Century ROAD to Housing Act takes effect January 7, 2027. The Mortgage Bankers Association reads the proposal as leaving sales of existing build-to-rent communities older than 18 months subject to the ban unless another exception applies. If your construction or bridge loan matures in the next 6 to 12 months and the payoff plan is a sale to a large buyer, date every certificate of occupancy now and price a refinance beside the sale.
Can a build-to-rent developer sell to a large investor under the ROAD Act?
Yes, a build-to-rent developer can sell to a large institutional investor once the ban starts, but under Treasury's proposal only for homes bought within 18 months of their certificate of occupancy, never owner-occupied and first occupied by renters, unless the sale fits another exception. The rule is still a proposal, and comments close November 23, 2026.
Section 1001 of the ROAD Act, enacted July 11, 2026, prohibits large institutional investors from purchasing single-family homes, subject to a list of excepted purchases that includes purchases made under a build-to-rent program. Treasury's notice of proposed rulemaking (FR Doc. 2026-21675, 91 FR 66799) says the statute's requirements and prohibitions take effect 180 days after enactment, on January 7, 2027. From that date a large institutional investor may not purchase, or enter into a contract to directly or indirectly purchase, a single-family home unless an exception applies. The contract language matters to any developer holding a forward-purchase or takeout agreement with a large buyer, so put that agreement in front of counsel before the effective date.
ROAD Act enacted (Treasury proposed rule, Oct 23, 2026): July 11, 2026
Purchase ban takes effect (Treasury proposed rule): January 7, 2027
Comment deadline (Federal Register, Oct 23, 2026): November 23, 2026
Large-investor threshold (Treasury proposed rule): 350 single-family homes
Build-to-rent purchase window (proposed 31 CFR 36.5): within 18 months of the certificate of occupancy
Maximum civil penalty (Treasury proposed rule): the greater of $1 million per violation or three times the purchase price
The Mortgage Bankers Association's commercial real estate finance policy update, dated October 27, 2026 and run in its October 29 NewsLink, says the 18-month limit would significantly limit owners' ability to sell horizontal multifamily communities. MBA writes that it has consistently advocated for exempting existing build-to-rent communities from the ban and plans to submit comments.
Who counts as a large institutional investor under the ROAD Act?
A large institutional investor is a for-profit entity in the business of investing in, owning, renting, managing or holding single-family homes that, alone or in concert, directly or indirectly has investment control of at least 350 of them, excluding homes bought in an excepted purchase after enactment, as Treasury summarizes the statute.
The count reaches further than a buyer's own deeds. Treasury's proposal explains that investment control includes owning or controlling more than 25 percent of any class of equity interests in the entity that owns the home, unless the holder is a passive investor. Proposed 31 CFR 36.16 makes an equity holder passive only if none of its directors, officers, employees or designees sits as a director or officer of the owning entity, and it holds no property control right. Proposed 31 CFR 36.2 defines that right as a consent, approval, veto or other right to make, direct or prevent decisions on the purchase, sale, holding, leasing, renovation or management of a single-family home, and Treasury is not proposing a safe harbor for minority-investor protective rights.
Proposed 31 CFR 36.15 treats an entity as in the business when it holds homes for investment gains, rental income, management fees or any other financial gain. An entity that holds homes only temporarily and incidentally to a different bona fide business is outside that definition, and Treasury says a fee-based property manager without investment control over the homes is not a large institutional investor.
The penalty sets the stakes for a buyer. Section 1001(d)(1) authorizes a civil penalty of up to the greater of $1 million per violation or three times the purchase price of the property, and proposed 31 CFR 36.17 would count one purchase involving several large institutional investors as a single violation for that maximum.
What counts as a build-to-rent purchase under Treasury's proposal?
Under proposed 31 CFR 36.5, a build-to-rent purchase qualifies only if the home was never occupied by an owner-occupant, is bought within 18 months of receiving its certificate of occupancy or equivalent, and is first occupied by renters after the purchase, under a written program the buyer adopted before buying.
The statute excepts purchases under a build-to-rent program in which the large institutional investor purchases, constructs, or constructs and retains newly constructed single-family homes to be managed as a rental property, in an all-rental community or a mixed owner and renter community. Treasury reads newly constructed as excluding homes an owner-occupant has lived in, reads managed as a rental property as requiring initial rental use, and proposes the 18-month certificate-of-occupancy line as an administrable test. The proposal says the strongest evidence of rental intent is that the buyer actually rents the home, and it does not bar the buyer from selling the home later.
Proposed 31 CFR 36.3 defines the program itself as written policies or procedures adopted before the purchase and reasonably designed and implemented so every purchase meets the Act. Treasury expects a buyer relying on the exception to keep certificates of occupancy or construction records, records showing no prior owner-occupant, and leasing records showing the first occupant was a renter. Those records come from the developer, so assemble them by home as each phase delivers.
The definition of a single-family home also matters. MBA quotes the statute: a structure that contains two or fewer dwelling units, each intended for occupancy by a single household, and that is not a manufactured home. On that wording a triplex building or a manufactured home is not a single-family home, so have counsel confirm how each building type in your community is counted before you rely on any exception.
What happens to a build-to-rent community after 18 months?
After 18 months from a home's certificate of occupancy, a sale of that home to a large institutional investor no longer fits the proposed build-to-rent exception, and MBA reads the proposal as leaving those sales subject to the ban unless another exception applies, which pushes the developer toward a smaller buyer or a refinance.
Treasury considered the broader reading. Its proposal describes an alternative that would cover homes originally constructed to be rented that have remained rented, which would bring existing communities inside the exception, and says that reading appears inconsistent with the statutory text and purpose. It also considered time-bound versions, such as homes built after enactment, and asks commenters whether 18 months is the right period. None of that is final until Treasury adopts a rule.
The other exceptions are narrow for a developer. Proposed 31 CFR 36.11 lets a large institutional investor buy from another large institutional investor only if the seller owned the home on July 11, 2026 or bought it in compliance with the Act. The homeownership and boost-homeownership exceptions require the buyer to sign leases with specified terms, including positive rent reporting and meaningful financial support toward a purchase. The renovate-to-rent exception requires homes that fail structural or core code elements at purchase and improvements of at least 15 percent of the structure's price, which a new community does not fit.
Illustrative example (our arithmetic, not a real transaction): a 120-home community delivered in three phases of 40 homes, with certificates of occupancy in April 2025, November 2025 and May 2026. Its construction loan matures in June 2027 and the plan is a sale to a large buyer.
- Phase 1 leaves the 18-month window in October 2026, before the ban starts.
- Phase 2 leaves the window in May 2027.
- Phase 3 stays inside the window until November 2027.
The counts assume every home is still vacant at closing. Proposed 31 CFR 36.5(c) requires each home to be first occupied by renters after the purchase, so a home the developer leases before closing falls outside the exception whatever its certificate-of-occupancy date. With every home vacant, a closing in April 2027 leaves 40 of 120 homes outside the exception and a closing that slips to June 2027 leaves 80 of 120 outside it. If the developer leases up Phase 2 and Phase 3 before an April closing, all 120 fall outside it. In this example the closing date and the leasing plan move the buyer pool more than the price does.

What loan replaces a sale to a large investor?
When the large-investor sale is closed off, the replacement is usually a refinance that pays off the construction or bridge loan and lets the developer hold the community: HUD's Section 223(f) while the certificate of occupancy is under three years old, a permanent bank or institutional loan, or a short bridge while the proposal is pending.
HUD's Mortgagee Letter 2026-12, announced October 14, 2026 and effective immediately, makes build-to-rent communities of detached homes, duplexes or triplexes eligible for Section 223(f) acquisition or refinancing when the certificate of occupancy is dated less than three years before the application. The community needs five or more dwelling units on one contiguous site, operated as one rental property, and HUD will not approve sales of parcels, buildings or any partial release of collateral during the insured loan term. The letter's details are in our guide to using a HUD loan for a build-to-rent community.
The two clocks run from the same document. The proposed build-to-rent exception closes 18 months after a home's certificate of occupancy, and HUD's 223(f) test asks for a certificate of occupancy dated less than three years before the application, so between month 18 and month 36 the exception no longer covers a large-buyer sale while the HUD refinance can still be open. In a phased community with several certificates of occupancy, that overlap differs by phase, so confirm with the HUD lender which date governs the application. A 223(f) loan suits a hold, not a home-by-home sale program, because of the release rule.
A conventional permanent loan or a bridge can fill the same role on a different timeline. A bridge buys time while the proposal is pending, at floating-rate cost; a fixed-rate permanent loan locks in the hold. The stage-by-stage view of how build-to-rent loans work from construction through lease-up and the build-to-rent loan page cover how lenders size each step.
Federal funds target range (FOMC statement, Oct 28, 2026): 3-3/4 to 4 percent, held
10-year Treasury yield (FRED DGS10, Oct 28, 2026): 5.05%
SOFR (FRED, Oct 28, 2026): 3.94%
Fixed-rate permanent loans generally price off Treasury yields and floating bridge loans off SOFR, so those two observations frame the hold-versus-bridge choice on the day you size it. Ask every lender whether it sizes the takeout on the rent roll and the hold, or on a sale price that assumes a large buyer.
How do I get a build-to-rent refinance placed when a large-investor sale is off the table?
YieldStack publishes this guide, and our recommendation is to place a build-to-rent refinance through a commercial mortgage brokerage that packages the community once, with every certificate of occupancy date, and tests a HUD 223(f), a permanent loan and a bridge side by side before the construction loan matures.
Option 1, the brokerage route (our recommendation). YieldStack is an AI-native commercial mortgage brokerage that arranges financing for commercial real estate investors. Software matches the deal against 20,000+ loan programs and compares the options; human brokers structure the deal, negotiate on the borrower's side and carry it toward closing. The median first offer arrives in under an hour, from an institutional lender. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
Option 2, an extension from the construction lender. Your current lender may extend the maturity, but you see one lender's terms, and an extension buys time without settling the hold.
Option 3, one HUD lender for 223(f). A single HUD-approved lender can take a 223(f) application, but you run the bank and bridge comparisons yourself and carry the three-year deadline alone.
For a build-to-rent refinance after a blocked sale, the package that gets clean answers carries:
- Certificate of occupancy date for every home, grouped by phase
- Leasing records showing each home's first occupant was a renter who moved in after the buyer's purchase
- Any purchase, forward-purchase or takeout agreement with a large buyer
- Construction loan balance, maturity date and extension terms
- Trailing operating statements, site plan and parcel map
When the package is ready, send the build-to-rent community for a refinance comparison.
The bottom line
Yes, a build-to-rent developer can still sell to a large institutional investor under Treasury's ROAD Act proposal, but the build-to-rent exception covers only homes never owner-occupied, bought within 18 months of their certificate of occupancy and first rented; older homes need another exception. The ban starts January 7, 2027 and comments close November 23, 2026.
Date every home, model the closing slipping a quarter, and line up a refinance, HUD 223(f) inside three years or a permanent or bridge loan, before your construction loan matures.
