Senate proposals target institutional single-family landlords: what the bills do and who feels it

What’s being proposed

The latest Senate activity includes two different proposals aimed at large-scale investors in single-family housing. One is the *Homes for American Families Act*, which would amend the Sherman Antitrust Act to make it illegal for investment funds with more than $150 million in assets to buy single-family homes, condos, or townhouses (while carving out homebuilders constructing homes for sale).

A separate proposal, the *American Homeownership Act*, takes a tax-code approach. Rather than banning ownership outright, it would deny interest deductions and depreciation deductions tied to certain residential rental property when a large institutional entity or a "large owner" holds a majority interest.

How the tax bill changes investor economics

The bill’s key trigger for single-family rentals is its definition of a "large owner": a person who holds a majority interest in single-family residential rental properties that, in aggregate, contain **50 or more dwelling units**. [banking.senate.gov]

If that threshold is met, the proposal would disallow (1) interest deductions related to the covered properties and (2) depreciation deductions on the covered properties. Those two items are foundational to how many rental portfolios are financed and underwritten, so the change is designed to pressure the economics of large-scale ownership. [banking.senate.gov]

The bill also includes exceptions intended to protect or encourage supply-related activities. Examples include:

• **Sales exception** for the taxable year in which property is sold to an individual who will use it as a principal residence, or to a qualifying nonprofit focused on affordable housing. [banking.senate.gov]
• **New single-family housing exception**: for newly built single-family homes placed in service after December 31, 2023, the builder can keep interest deductibility for a 5-taxable-year period. [banking.senate.gov]
• **Affordable housing and rehab exceptions** (including certain federally assisted housing/LIHTC-related properties and substantial rehabilitation of uninhabitable homes). [banking.senate.gov]

How big is institutional ownership, really?

A central debate is scale. Urban Institute analysis has found large institutional investors own only about **3% of single-family rentals nationally** and less than **0.5%** of the total single-family housing stock—while still showing much higher shares in certain metros (e.g., Atlanta, Jacksonville, Charlotte). [urban.org]

That concentration is why policy aimed at large landlords can feel locally material even if it is nationally modest. In markets where institutional SFR operators represent a large share of rentals, changes in acquisition behavior—or pressured selling—could influence for-sale inventory and buyer competition more quickly than in markets where investor ownership is thin. [urban.org]

What to watch next

Three practical questions will drive real-world impact: 1) **Definitions and thresholds**: which entities and ownership structures get captured by the rules, and how aggregation rules apply. [banking.senate.gov] 2) **Enforcement and timelines**: how quickly changes would affect acquisition pipelines or existing portfolios. [cbsnews.com] 3) **Supply offsets**: whether the carve-outs for new construction and rehab are enough to avoid suppressing build-to-rent or renovation activity that can add usable housing. [banking.senate.gov]

For now, the most reasonable expectation is uneven impact: metros with heavier institutional presence are more likely to see changes in investor bidding and turnover, while most markets may feel little direct effect compared with the broader issue of overall housing supply.
