New Mexico rules

Redemption
The pre-sale window is long even though there is no post-sale redemption: taxes go delinquent thirty days after each due date, the account transfers to the state after two years, the property cannot be sold until three years after the first delinquency date on the list, and the owner must receive certified-mail notice twenty to thirty days before the sale, as must each recorded lienholder whose address is reasonably ascertainable. Installment agreements run up to thirty-six months at one percent a month and cannot be entered on or after the date of the initial sale. After the sale the only exposure is the former owner's two-year window to challenge the conveyance in district court, and, where a federal tax lien is recorded, the 120-day federal redemption right the Property Tax Division's terms warn about.
Deed deposit
None. The statute sets no bidder deposit and no registration fee. Bidders register in person on the day of the sale, registration opening at 8:00 a.m. and closing when the 10:00 a.m. auction starts, and bid orally in person or through an agent carrying a notarized authorization. A personal or business check is accepted only with a letter of guarantee from the issuing bank presented at registration.
Surplus proceeds
Sale money goes first to the department's costs, then to penalties and interest, then to the delinquent taxes, which are remitted to the county treasurer. The balance is paid to the former owner, or to anyone a court orders, after the department may first apply it to other property taxes that person owes, and the department may require proof of former ownership. If no former owner claims the balance within two years of the sale after a reasonable search, it is treated as abandoned property under the Uniform Unclaimed Property Act.
Governing statute
NMSA 1978, Chapter 7, Article 38 (7-38-60 through 7-38-74)

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
