Neighborhood Homes Investment Act This bill allows a business-related tax credit for certain development costs for the acquisition, rehabilitation, or remediation of qualified real property (i.e., real property affixed on a permanent foundation and comprised of four or fewer residential units, a condominium unit, or a house or apartment owned by a cooperative housing corporation). The bill also provides for the exclusion from gross income, for income tax purposes, of the value of any subsidy provided to a taxpayer by any state energy office for purposes of improvements made to a qualified residence.
