Tax Foreclosure in New Mexico: What Homeowners Need to Know

A guide from AuctionBlock.org — a mission-driven company dedicated to foreclosure prevention education


New Mexico uses a property tax delinquency system that can lead to a tax deed through a judicial proceeding. The county sells the property, not a lien, after obtaining a court order.

How It Works

Property taxes in New Mexico are collected by the county treasurer. Under NMSA 1978, § 7-38-50 et seq., when taxes become delinquent, the county treasurer sends notice to the property owner. Penalties (1% per month, up to 5%) and interest (1% per month) accrue on the unpaid amount.

After taxes remain delinquent for 3 years, the county can petition the district court for an order to sell the property (NMSA § 7-38-65 et seq.). The court must approve the sale, and the property is sold at a public auction.

Redemption Period

Under NMSA § 7-38-70, the property owner can redeem the property by paying all delinquent taxes, penalties, interest, and costs before the sale date. Once the property is sold, there is generally no post-sale redemption period. However, the property owner can challenge the sale in court within certain timeframes if proper procedures were not followed.

Key Programs and Exemptions

Head of Family Exemption: Under NMSA § 7-36-7, qualifying heads of household may receive a property tax exemption on the first $2,000 of assessed value of their primary residence. Apply through your county assessor.

Veterans Exemption: Under N.M. Const. Art. VIII, § 5 and NMSA § 7-37-5, qualifying veterans may receive a property tax exemption on the first $4,000 of assessed value. Disabled veterans with a 100% rating are exempt on the full value. Apply through your county assessor.

Low-Income Property Tax Rebate: Under the Taxation and Revenue Department's programs, qualifying low-income homeowners may apply for a property tax rebate. Check with the New Mexico Taxation and Revenue Department for current eligibility.
