Notwithstanding the foregoing, the Administrative Agent may, upon approval by the Township Council, and subject to the Court's approval, permit a moderate-income purchaser to buy a low-income unit if and only if the Administrative Agent can demonstrate that there is an insufficient number of eligible low-income purchasers in the housing region to permit prompt occupancy of the unit and all other reasonable efforts to attract a low-income purchaser, including pricing and financing incentives, have failed. Any such low-income unit that is sold to a moderate-income household shall retain the required pricing and pricing restrictions for a low-income unit.
