HB3745 caps ownership of single-family homes at 75

Imposes a $10,000-per-excess-residence excise tax and funds a Housing Trust Fund for down‑payment assistance.

The Brief

The American Neighborhoods Protection Act of 2025 would prohibit individuals and entities from owning more than 75 single-family residences and create a new excise tax on the excess. It defines single-family residence as properties with up to four dwelling units, and it lays out ownership and aggregation rules to treat related entities as a single taxpayer.

A reporting regime requires purchasers to disclose who is buying each property and imposes penalties for noncompliance. The bill also establishes a Housing Trust Fund funded by the new tax revenue and directs grants to state housing finance agencies to provide down‑payment assistance, with priority given to families purchasing homes sold by a covered taxpayer.

The package is effective for taxable years beginning after December 31, 2025.

At a Glance

What It Does

Creates a new Chapter 50B in the Internal Revenue Code: imposes a tax on the excess number of single-family residences owned, defines ownership and aggregation, and sets reporting requirements for purchasers. The measure also provides penalties for failure to report and links the tax to a housing-financing program.

Who It Affects

Primarily owners of four-unit-and-smaller properties who own more than 75 such residences, including aggregated related entities. Exemptions carve out mortgage note holders, certain tax-exempt organizations, construction/rehab businesses, and owners of federally subsidized housing. Purchasers of covered properties face reporting obligations and potential penalties for noncompliance.

Why It Matters

If enacted, the bill shifts incentives around investors in small multifamily housing, directs tax revenue to a dedicated Housing Trust Fund, and aims to increase down‑payment assistance for families purchasing homes—including homes sold by large holders of SFR inventories. The proposal also signals how Congress might address concentration of small rental stock and funding for affordability programs.

What This Bill Actually Does

Section 1 of the bill provides the short title, naming the act the American Neighborhoods Protection Act of 2025. Section 2 adds a new tax regime (Chapter 50B) to the Internal Revenue Code.

It imposes an excise tax of $10,000 for each single-family residence owned in excess of 75 by a taxpayer for each taxable year, with ownership treated on an aggregate basis across related persons or entities. A definition for single-family residence limits the property to four dwelling units, and the ownership provision requires a direct majority interest to trigger ownership.

Special rules apply to certain sales so that ownership is preserved for purposes of the tax when properties are transferred to specified buyers. There are reporting requirements: purchasers must provide identifying information about buyers and indicate whether a sale falls under the described exclusion; penalties of $50,000 apply for failure to report or for incorrect reporting, with a reasonable-cause waiver available in certain circumstances.

Section 3 creates a Housing Trust Fund funded by the tax revenues and authorizes grants to state housing finance agencies to establish or expand down‑payment assistance programs. Priority for grants is given to families buying single-family residences sold by a covered taxpayer.

The administration of the grants is handled by the Department of Housing and Urban Development, and the funds are available through appropriations acts to support eligible programs.

Section 1

Short title

Section 1 names the act as the American Neighborhoods Protection Act of 2025. This establishes the formal designation under which the bill would be cited and implemented if enacted, framing the policy impulse behind the substantive provisions that follow.

Section 2

Excess single-family residences tax

Section 2 creates Chapter 50B of Subtitle D in the Internal Revenue Code and imposes an excise tax on the excess number of single-family residences a taxpayer owns beyond the 75‑unit cap. The tax is $10,000 per excess residence for each taxable year. It defines ownership as a direct majority ownership interest and applies aggregation rules to treat related persons or entities as a single taxpayer. It also introduces a set of special sale rules intended to preserve the counting framework for certain transfers and details a reporting regime with a $50,000 penalty for failure to report or for inaccurate reporting.

Section 3

Housing Trust Fund and grants for down payment assistance

Section 3 establishes a Housing Trust Fund funded by the revenues from the tax, to be used for eligible grants via appropriations acts. It directs the Department of Housing and Urban Development to create a grants program that provides funds to state housing finance agencies to support down‑payment assistance programs. Grants are prioritized for families seeking to purchase single-family residences that are sold by a covered taxpayer, linking the tax to a targeted affordability objective.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • First‑time homebuyers and families in states with active down‑payment assistance programs who qualify for grants to purchase homes.
  • State housing finance agencies that receive grants to expand or establish down‑payment assistance initiatives.
  • Communities in which housing stability is improved through increased access to affordable purchases of homes sold by large owners of SFRs.

Who Bears the Cost

  • Owners of more than 75 single-family residences or related entities considered a single taxpayer for purposes of the cap and tax.
  • Investors and landlords with large portfolios of single-family residences, who would face the excise tax on excess holdings.
  • Purchasers and market participants subject to reporting obligations and potential penalties for noncompliance, as well as the broader housing market entities that may adjust behavior in response to the tax and aggregation rules.

Key Issues

The Core Tension

The central dilemma is whether a capital-constraining tax and ownership cap will meaningfully reduce investor concentration without undermining housing supply or price stability, and whether the targeted housing grants can reliably translate tax revenue into meaningful down‑payment relief for families living in communities affected by high SFR ownership.

The bill’s approach raises policy tensions around investor concentration, housing supply, and affordability. The cap only applies to single-family residences and relies on taxation and reporting to deter concentration, but it could incentivize restructurings or sales to avoid counting.

The exempted categories and the aggregation rules add complexity and potential circumvention risk, while the timing—effective for tax years after 2025—creates a transition period for affected owners and markets. The reliance on a federal tax mechanism to fund state-level grants also raises questions about the sufficiency and administration of the Housing Trust Fund, and how prioritization rules will translate into real-world down‑payment outcomes.
