Within thirty days after the receipt of the notice, the board in writing shall notify the original purchaser at the specified address whether it elects to exercise the option. If the board refuses, or fails within the thirty-day period, to reply to the offer, the original purchaser may sell the property to any other person free from any price restrictions; provided that if the board elects to purchase, the board shall use its best efforts to redispose of the property as soon as practicable subject to the lien of any mortgage, to a qualified and responsible person who will assume the obligation of mortgage and debt secured thereby.
