(7) The landlord has a lien on the mobile home and the proceeds of a sale conducted pursuant to subsection (6) for the reasonable costs of removal, storage, notice, sale, or delinquent rent or damages owing on the premises. The sale proceeds are subject to any prior security interest of record. A writing or recording is not necessary to create the lien provided for in this section. In the case of a sheriff's sale, the sheriff shall conduct the sale upon receipt of an affidavit from the landlord stating facts sufficient to warrant a sale under this section. After satisfaction of the lien, the landlord shall remit to the mobile home owner the remaining proceeds, if any. If the owner cannot after due diligence be found, the remaining proceeds must be deposited in the general fund of the county in which the sale occurred and, if not claimed within 3 years, are forfeited to the county.
