At least one week before the date of sale, the person who was the owner of any included parcel when it forfeited to the state for nonpayment of taxes, or the person’s heirs, successors or assigns or any person to whom the right to pay taxes on such lands was given by statute, mortgage, or other agreement, may purchase the parcel. The purchase price is the greater of (1) the appraised value of the parcel, or (2) the sum of all delinquent taxes and assessments, computed under section 282.251, together with penalties, interest, and costs, that accrued or would have accrued if the parcel had not forfeited to the state. The purchaser’s title and right is conditioned upon the primary use as designated by the resolution of the county board. The right of the purchaser to purchase shall be evidenced by the purchaser’s duly verified written application showing the qualifications required by this section and filed with the county auditor.
