(a)

(1) It is the duty of the county mayor of each county to take charge of all the lands bought in by the county at such delinquent tax sales.

(2) During the period when redemption of any such tract of land can be made, the land shall be:

(A) Held and put only to a use that will not result in a waste of the land; or

(B) Sold to a third party, in accordance with subsection (b), subject to the right of redemption. If any parcel is sold subject to redemption, it may be redeemed in accordance with § 67-5-2701.

(3) After the period of redemption has elapsed, it shall be the duty of the county mayor to arrange for the disposition of every tract of such land as expeditiously and advantageously as possible unless parcels acquired by the county are identified by the county mayor, or the mayor's designee, as being in an area or zoning classification that would make the accumulation of larger areas advantageous to the parcels' reuse and redevelopment. In such cases, the mayor may hold those properties until a sufficient number of parcels or area has been acquired to improve the parcels' marketability and redevelopment profile. In no event shall this accumulation result in property being held without being marketed for more than five (5) years.

(4) If the county mayor determines, prior to the sale of a parcel brought in by the county at a delinquent tax sale, that there may be a defect in the title to the parcel, the county mayor may move the court in which the parcel was sold in the tax proceeding, to take action to cure the defect. A diligent effort to give notice of any such motion shall be made as to all interested persons as of the date of the filing of the motion.

(b)

(1) A committee of four (4) members shall be elected by the county legislative body, from the county legislative body, who, together with the county mayor, shall place a fair price on each tract of land, for which price the land shall be sold. In counties having adopted the County Financial Management System of 1981, compiled in title 5, chapter 21, the financial management committee created by § 5-21-104 may serve as this committee, instead of the committee as established in this subdivision (b)(1).

(2) Such committee may authorize the sale of any tract of land upon such terms as will secure the highest and best sale price, but the credit extended shall not exceed three (3) years and a lien shall be retained to secure purchase price.

(3) No tract of land shall be sold for an amount less than the total amount of the taxes, penalty, cost and interest, unless the legislative body, upon application, determines that it is impossible to sell the tract of land for this amount, and grants permission to offer the land for sale at some amount to be fixed by such legislative body.

(4) Interest shall be calculated on the full amount of the taxes, penalty, cost and interest from the time of the acquisition of the land by the county until the sale thereof.

(5) Whenever the sale of a tract of land is arranged by the county mayor, the deed shall not be executed and the sale shall not become final until ten (10) days after the publication in a newspaper published in the county of a notice of the proposed sale, the name of the purchaser and the terms, conditions and price. The land shall be described in the notice only by number, which shall refer to a description on file with such committee.

(6) If anyone, during such ten (10) days, increases the offer made for the land by ten percent (10%) or more, the party making the first offer shall be notified and a day fixed when both parties shall appear and make offers.

(7) The tract of land shall be sold to the party making the highest and best offer.

(8) Conveyances of the land shall be made without warranties of any sort, and deeds shall be executed by the county mayor or other chief fiscal officer of the county.

(9) The deed shall be prepared by the back-tax attorney as a part of the duties for which the attorney is compensated by § 67-5-2410, and no additional compensation shall be allowed.

(10) The county may, upon a majority vote of its legislative body determining it in the best interests of the county to use the property for a public purpose, decide to retain ownership and possession of such property.

(11) This subsection (b) shall not apply in any county having a metropolitan form of government and a population in excess of five hundred thousand (500,000), according to the 2010 federal census or any subsequent federal census.

(c)

(1) As to a particular parcel conveyed to a county pursuant to § 67-5-2501, the county mayor may make an evaluation of the parcel to determine whether the value of the parcel or amount of money the county is likely to receive if the county sold the parcel exceeds the financial obligations or environmental risks associated with the parcel.

(2) If the county mayor determines that such financial obligations or environmental risks exceed the value of the parcel, the county legislative body may adopt a resolution, by a two-thirds (⅔) vote, concurring in the county mayor's determination and directing the county mayor to request relief from the court in which the parcel was sold. Such relief shall be sought by motion pursuant to Rule 60 of the Tennessee Rules of Civil Procedure filed within one hundred twenty (120) days after the entry of the order confirming the sale.

(3) If the court finds that the motion should be granted, the court may rescind its prior order upon such terms as are just. In the event the prior order is rescinded, title to the parcel shall be deemed to have remained in that state which existed as of the date of entry of the prior order confirming the sale. The court shall have broad discretion to ensure that this subsection (c) does not result for any period of time in the creation of a parcel for which no person or entity has responsibility. The court may then appoint a special master and direct the special master to conduct a second sale of the parcel upon such terms and conditions as may be ordered by the court, including the reduction or elimination of the minimum bid that may be accepted at the sale.

(4) In the event no person presents a bid at the second sale of the parcel, the court may thereafter approve a negotiated sale of the parcel upon such terms and conditions as may be ordered by the court or such other relief as the court may order, including the conveyance to a nongovernmental entity claiming contractual rights to dues or assessments pursuant to § 67-5-2516.

(5) This subsection (c) shall be applicable to the financial obligations or environmental risks of an individual parcel only and shall not be applicable to the aggregated financial obligations or environmental risks of all or multiple parcels bid in to the county pursuant to § 67-5-2501.
