The county auditor shall offer each tract separately, beginning with the first tract contained in the list.
If a parcel sells for less than the total amount of the taxes, assessments, penalties, interest, and costs that stand charged against it, the officer conducting the sale shall require the buyer to complete an affidavit prepared by the officer stating that the buyer is not the owner of record immediately prior to the judgment of foreclosure or foreclosure and forfeiture, or a member of the specified class of parties connected to that owner, and the affidavit shall become part of the court records of the proceeding. If the county auditor discovers within three years after the date of the sale that a parcel was sold to that owner or a member of the specified class of parties connected to that owner for a price less than the amount so described, and if the parcel is still owned by that owner or a member of the specified class of parties connected to that owner, the auditor within thirty days after such discovery shall add the difference between that amount and the sale price to the amount of taxes that then stand charged against the parcel and is payable at the next succeeding date for payment of real property taxes. As used in this paragraph, "immediate family" means a spouse who resides in the same household and children.
