(3) A commission on the sale of a factory-built home located in the factory-built home rental community unless the tenant expressly employs the landlord to perform a service in connection with the sale, but employment of the landlord by the tenant may not be a condition or term of the initial sale or rental; or
(4) A fee for improvements or installations on the interior of a factory-built home, unless the tenant expressly employs the landlord to perform a service in connection with such installation, improvement or sale.
(b) An invitee of the tenant has free access to the tenant's factory-built home site without charge unless a court of competent jurisdiction has ordered otherwise.
