When real property is bought by the county at a delinquent tax sale due to the lack of an adequate bid by another party, after the year for redemption has passed the county is obligated to resell the real property bid in by the county. The county legislative body elects four people from its membership who, with the county mayor, form a committee to place a fair price on each tract of land bought by the county at delinquent tax sales. T.C.A. § 67-5-2507.
