The officer charged with the duty to sell real property and mobile or manufactured housing for nonpayment of ad valorem property taxes shall submit a bid on behalf of the forfeited land commission equal to the amount of all unpaid property taxes, penalties, assessments including, but not limited to, assessments owed to a special taxing district established pursuant to Section 4-9-30, Chapter 19, Title 4, or an assessment district established pursuant to Chapter 15, Title 6, and costs including taxes levied for the year in which the redemption period begins. The forfeited land commission is not required to bid on property known or reasonably suspected to be contaminated. If the contamination becomes known after the bid or while the commission holds the title, the title is voidable at the election of the commission.
