Prohibits certain institutional investors from purchasing or acquiring single-family homes.

Bill A5451 prohibits most institutional investors (such as large real estate firms, corporations, or trusts owning significant properties) from purchasing or acquiring single-family homes in New Jersey, including townhomes. Key exemptions include nonprofits developing affordable housing, family trusts, family LLCs, small investors owning four or fewer homes, and properties acquired through foreclosure. Violators must sell the home within six months and pay profits to the state, with daily fines of $500 for first offenses. The law requires annual reporting to the Department of Community Affairs and applies to all home purchases after its effective date.
