In computing the rental for the purpose of this section, there shall be included therein the average annual cost, as determined by the authority, to occupants of heat, water, electricity, gas, cooking range and other necessary services or facilities, whether or not the charge for such services and facilities is in fact included in the rental.
In determining net income for the purpose of tenant eligibility with respect to a low-rent housing project financed by the commonwealth or by any city, town or other political subdivision thereof or administered by a housing authority under the provisions of this chapter or as agent for any municipality, the housing authority is authorized, where it finds such action equitable and in the public interest, to exclude amounts or portions thereof paid by the United States government or the commonwealth or any of its political subdivisions to the tenant for disability occurring in connection with military service. In determining the net income for the purpose of computing the rent of a totally unemployable disabled veteran, a housing authority shall exclude amounts of disability compensation paid by the United States government for disability occurring in connection with military service in excess of $1,800 in any month; provided, however, that such exclusion shall apply only to state-aided projects as provided in sections 35 and 36.
In determining the net income of the tenant family for the purpose of computing the rent and determining eligibility for admission and continued occupancy, proceeds paid to such tenant family from policies of insurance shall be excluded from income.
