"New Jersey Neighborhood Homes Investment Act"; establishes gross income tax credit for certain residential development.

This bill creates a tax credit for developers building or renovating affordable housing in New Jersey. It directly affects project sponsors (developers) who construct or substantially renovate qualifying homes sold at affordable prices to eligible homeowners earning 140% or less of the state's median household income. The credit equals the difference between reasonable development costs and the affordable sale price, capped at 35% of development costs or 80% of the state's median new home price. To qualify, projects must be in designated census tracts and certified by the New Jersey Housing Agency, with homes sold as primary residences.
