A tenant may rescind an earnest money agreement or any other acceptance of an offer of sale or exercise of first right of refusal by delivery to the developer, by registered or certified mail return receipt requested, written notice of revocation within 10 days of acceptance of the offer. Upon receipt of a timely revocation the developer shall immediately refund any deposit, earnest money, or other funds, and the parties shall have no further rights or liabilities under the purchase agreement. Developers shall include in their sales contracts a clause informing purchasers of their rights under this section. The clause shall be located either immediately above the purchaser’s signature or under a separate conspicuous caption entitled "Purchaser’s Right to Cancel." In addition, each binding sale agreement shall provide that the prevailing party in any action to enforce rights under the agreement shall be entitled to reasonable attorney’s fees. (Amended by Res. 79-339, Nov. 13, 1979).
