repaired said damage and can prove that the renewed damage was unrelated to the prior damage and was caused by the tenant or by any person under the tenant's control or on the premises with the tenant's consent. Nothing in this section shall limit the right of a landlord to recover from a tenant, who wilfully or maliciously destroys or damages the real or personal property of said landlord, to the forfeiture of a security deposit, when the cost of repairing or replacing such property exceeds the amount of such security deposit.
No deduction may be made from the security deposit for any purpose other than those set forth in this section.
(5) Whenever a lessor who receives a security deposit transfers his interest in the dwelling unit for which the security deposit is held, whether by sale, assignment, death, appointment of a receiver or trustee in bankruptcy, or otherwise, the lessor shall transfer such security deposit together with any interest which has accrued thereon for the benefit of the tenant who made such security deposit to his successor in interest, and said successor in interest shall be liable for the retention and return of said security deposit in accordance with the provisions of this section from the date upon which said transfer is made; provided however, that the granting of a mortgage on such premises shall not be a transfer of interest. The successor in interest shall, within forty-five days from the date of said transfer, notify the tenant who made such security deposit that such security deposit was transferred to him and that he is holding said security deposit. Such notice shall also contain the lessor's name, business address, and business telephone number, and the name, business address, and business telephone number of his agent, if any.
