The bill seeks to limit tax deductions for interest and depreciation on residential rental properties, impacting institutional investors and large single-family property owners. Exceptions include sales to individuals, new housing, uninhabitable housing preservation, and affordable housing. The Treasury Secretary can issue regulations. It also aims to prioritize affordable housing and homeownership, increase funding, assist homebuyers, impose scrutiny on property acquisitions, define covered entities and qualified homebuyers, allocate funding, and establish antitrust enforcement presumptions. These changes will apply for taxable years starting after the bill's enactment.
