The provisions of sections 20-500 to 20-528, inclusive, concerning the certification or provisional licensing of real estate appraisers shall not apply to (1) any person under contract with a municipality who performs a revaluation of real estate for assessment purposes pursuant to section 12-62, and (2) any licensed real estate broker or real estate salesperson who estimates the value of real estate as part of a market analysis performed for the owner of the real estate or a designee of the owner, on such terms as may be agreed upon between such owner or the owner’s designee and the real estate broker or real estate salesperson, for the purpose of (A) a prospective listing or sale of such real estate, (B) providing information to the seller or landlord under a listing agreement, or (C) providing information to a prospective buyer or tenant under a buyer or tenant agency agreement, provided such estimate of value shall not be referred to or be construed as an appraisal. If such owner executes a listing contract with the real estate broker or real estate salesperson who so estimated the value of the real estate for the sale of the real estate and such real estate contains any building or other structure, occupied or intended to be occupied by no more than four families, then such owner shall be credited against any compensation the owner pays on account of such listing contract for any fee paid by the owner for such estimate of value.
