The purchaser or his or her assignee of a mobile home sold for nonpayment of taxes may extend the period of redemption at any time before the expiration of the original period of redemption, or thereafter prior to the expiration of any extended period of redemption, for a period which will expire not later than 3 years from the date of sale, by filing with the county clerk of the county in which the mobile home is located a written notice to that effect describing the mobile home, stating the date of the sale and specifying the extended period of redemption. If prior to the expiration of the period of redemption or extended period of redemption a petition for tax certificate of title has been filed under Section 390, upon application of the petitioner, the court shall allow the purchaser or his or her assignee to extend the period of redemption after expiration of the original period or any extended period of redemption, provided that any extension allowed will expire not later than 3 years from the date of sale. If the period of redemption is extended, the purchaser or his or her assignee must give the notices provided for in Section 370 at the specified times prior to the expiration of the extended period of redemption by causing a sheriff (or if he or she is disqualified, a coroner) of the county in which the mobile home, or any part thereof, is located to serve the notices as provided in Sections 375 and 380. The notices may also be served as provided in Sections 375 and 380 by a special process server.
