Stop Predatory Investing Act

This bill disallows tax deductions for interest and depreciation on rental properties owned by individuals or entities holding 50 or more single-family homes (defined as properties with four or fewer units). It directly affects large-scale landlords, including corporations or investors who own extensive rental portfolios, by removing these deductions from taxable income. Exceptions apply if the property is sold to an individual for their primary residence or to a qualified nonprofit organization focused on affordable housing (like community land trusts or housing nonprofits). The law aims to limit tax benefits for investors who own many rental homes, while preserving deductions for sales that support housing affordability. It takes effect for taxable years after enactment.
