This subsection applies to a person who sells a mobile home and, in connection with the sale: Is, or acts as an agent for, the owner of the park in which the home is to be located; and Negotiates with the buyer to place the home in a park. Prior to the execution of a contract for the sale of a mobile home, the seller of the mobile home shall provide to the buyer a copy of any rules established under Subtitle 3 of this title by the owner of the park in which the mobile home is to be located. A contract is unenforceable by a person described in paragraph (1) of this subsection if the person does not comply with paragraph (2) of this subsection. If subsection (a) of this section does not apply, the seller shall provide the buyer with a notice, in writing, separate from the contract, and in substantially the following form: “If the mobile home you are purchasing is to be placed in a mobile home park, the park may have rules and lease provisions that affect you and your home. You should contact the park office to obtain and carefully review a copy of the lease and rules for the park before you enter into a contract to purchase a mobile home. Due to land use restrictions in many areas in this State, a mobile home may be placed only on property that is within a mobile home park.”
