Tennessee Code Title 67. Taxes and Licenses § 67-5-2503

(a) An order confirming the sale of a parcel shall confer the right to possession of the parcel to the purchaser effective upon entry of the order. On such date, the risk of loss shall transfer from the original owner to the purchaser. In the event of a loss occurring after the sale and before the order confirming the sale is entered, the court shall, on motion of the purchaser filed before the order confirming the sale becomes final, determine whether any portion of the purchaser's bid should be refunded to the purchaser.

(b) A writ of possession shall, upon application of the purchaser, in a proper case, be ordered by the court in which the tax sale has been made. A purchaser not making an advance demand for rents or profits shall have no rights to rents or profits from a taxpayer who has remained in possession during the redemption period.
