Oregon HB 4128 90-Day Wait for Institutional Buyers Starts January 1, 2027
Oregon’s HB 4128 is now Chapter 64 of the 2026 Oregon Laws. It creates a 90-day public-listing waiting period before certain large institutional buyers can offer on or purchase a single-family residence.
The measure takes effect January 1, 2027, the effective date shown on Chapter 64 (the default date for 2026 legislation without an emergency clause). The waiting period applies to offers to purchase or acquire made on or after that date.
The Oregon HB 4128 90-day wait for institutional buyers is not a ban on institutional ownership of single-family homes. It is a timing and disclosure rule that applies only to a narrow set of very large buyers.
How the Oregon HB 4128 90-day wait for institutional buyers works
A covered entity may not purchase, acquire, or offer to purchase or acquire fee title to a single-family residence unless the home has been publicly listed for sale for at least 90 consecutive days immediately before the covered entity first offers or accepts an offer, or another exemption applies.
The clock starts with a public listing.
The 90-day rule does not apply to a home that:
Will be used as the principal residence of a person with an ownership interest in the covered entity;
Was built, or will be purchased, acquired or operated, with any federal, state or local government funds;
Is occupied by a tenant;
Was built for occupancy by a tenant and has never been occupied by anyone other than a tenant;
Is not publicly listed for sale at the time the covered entity makes its offer; or
Is acquired through a judicial or nonjudicial foreclosure sale, forfeiture, a deed in lieu of foreclosure, or enforcement of a judgment, lien, debt or property interest.
Because a home that is not publicly listed when the covered entity makes its offer is exempt, off-market and pre-listing deals are not blocked by the waiting period. Chapter 64 also has no provision that restarts the 90 days when a seller changes the listing price.
Who is a covered entity
A covered entity is an institutional real estate investor or an entity that receives funding from an institutional real estate investor to purchase a single-family residence.
An institutional real estate investor generally means an entity or related group that:
Owns 2,500 or more single-family residences, or has an ownership interest of at least 10 percent in 2,500 or more single-family residences, and
Serves as a fiduciary for pooled investment funds and manages at least $1 billion in net value or assets (subject to annual inflation adjustments).
Most local landlords, individual investors, and small-to-mid-size operators fall outside these thresholds. The rule is aimed at the largest national or institutional players, not the owner of a handful of Oregon rentals.
Certain entities are excluded: 501(c)(3) nonprofits; creditors or their loan servicers that acquire property in full or partial satisfaction of a secured debt; entities that get a loan or funding from an institutional investor in exchange for a mortgage of a type the general public can apply for; community land trusts; land banks; public housing authorities; and resident-owned cooperatives. Middle housing is not a “single-family residence” under the law.
and now a couple shameless plugs.

Disclosure and enforcement
When a covered entity makes or accepts an offer under the 90-day listing rule, it must submit a completed and notarized disclosure form to the seller or the seller’s agent. The form identifies the buyer as a covered entity subject to the 90-day waiting period.
Within three days of submitting the form to the seller, the covered entity must also send a copy to the Oregon Department of Justice.
Enforcement belongs to the Attorney General, not private parties. The Attorney General may investigate, bring civil actions, and impose civil penalties of up to $250,000 for a purchase that violates the waiting period and up to $10,000 for failing to submit a required disclosure form.
What this means for ordinary landlords and investors
If you are a local owner, small investor, or typical Portland-area landlord, HB 4128 does not change how you buy or sell single-family homes. You are not a covered entity under the statutory thresholds, unless an institutional real estate investor funds your purchase beyond an ordinary mortgage that members of the public can apply for.
The practical effect is on the buyer pool for listed single-family homes. Very large institutional buyers must wait out the public listing period and file the required disclosure. That may slightly reduce early competition from those specific buyers, but it does not create a general preference or restriction for ordinary purchasers.
The law does not alter Oregon’s rent-increase rules, termination rules, or other Chapter 90 landlord-tenant provisions. It is limited to the timing of certain institutional purchases of single-family residences.
Bottom line
Starting January 1, 2027, the largest institutional buyers must wait until a single-family home has been publicly listed for at least 90 consecutive days before they can offer or buy, unless an exemption applies. Most local landlords and individual investors are not subject to the rule. Covered buyers must also file a notarized disclosure with the seller and the Department of Justice.
Confirm the exact thresholds and exclusions against the enrolled Chapter 64 text and any later DOJ guidance before treating a specific buyer as covered or exempt.
