Union County tax sale
Short answer: the Union County tax sale is where parcels still unpaid at the end of New Mexico's collection process are sold. New Mexico is a deed state, so a winning bid buys the property. The date, the sale list and the terms are set in the official notice published before each sale, and the New Mexico Property Tax Division, which sells delinquent parcels from every New Mexico county keeps the delinquent roll behind it. The list shrinks right up to sale day as owners pay, and every owner on it was in the public record as delinquent before it was printed.

How a Union tax sale runs
A Union tax sale transfers the property itself. New Mexico is a deed state, so by the time a parcel reaches the auction the county has run its collection process, and the winning bid buys ownership rather than a certificate.
The owner's protection mostly sits before the auction: paying everything due takes a parcel off the list right up to sale day. That is why the published list overstates what actually sells, and why buyers who research only the final list see the least.

The sale list and the delinquent roll
They are two snapshots of the same record. The delinquent roll is everyone behind on Union property tax, kept year round. The sale list is the part of that roll still unpaid when the county advertises the sale, and it keeps shrinking until the auction as owners pay to keep their property.
That shrinking is the useful part. Every parcel that drops off is an owner who found the money under deadline; every parcel still listed a week out belongs to an owner who has not. Buyers who only read the final list meet those owners last, in a room full of other bidders. The full roll, and where the county publishes it, is on the Union County delinquent tax list page.
Before you bid in Union
What to settle before sale day for a tax deed sale.
Read the terms of sale
The notice sets the deposit, how and when the balance is due, the bidding method and whether bidding is online or in person. Missing a payment deadline can cost you the deposit.
Check the parcel, not the number
A sale list is parcel numbers and amounts owed. Map every parcel: lists routinely include slivers, landlocked lots and land you cannot build on, listed exactly like houses.
Budget for title work
A tax deed often needs a quiet title action before an insurer will cover it, and some liens can survive a tax sale. A title search before you bid is cheap next to a parcel you cannot sell.
Plan for occupants
A winning bid does not empty the house. If someone lives there, possession is a separate step with its own timeline, which belongs in your price.
Drive it
Online photos can be years old. Seeing the street, the roof and whether anyone lives there tells you more than any record on the list near Union County.
One of the smallest in the country
With about 3,926 residents, Union is far below the size most investors look at. When there is a list at all it is short, and the people bidding on it are mostly local.
Or buy before the sale
Months before a parcel reaches the Union sale list, the owner is already behind in the public record and still holds title. That is the window to inspect, run title and agree a price one to one.

Union County tax sale FAQ
When is the Union County tax sale in 2026?
The date is set locally and announced in the official sale notice ahead of the sale; the New Mexico Property Tax Division, which sells delinquent parcels from every New Mexico county is the place to start. The New Mexico pattern is the steadier guide. The state Property Tax Division auctions delinquent parcels; sales are final with narrow challenge windows.
Where can I get the Union County tax sale list?
Start with the New Mexico Property Tax Division, which sells delinquent parcels from every New Mexico county, which keeps the delinquent roll. The sale list comes with the sale notice, often as a PDF or spreadsheet of parcels and amounts due, and shrinks as owners pay. It does not show owner contact, values or which owners might sell first.
Does Union sell tax liens or tax deeds?
New Mexico is a deed state, so a winning bid at the Union sale buys the property. That makes it a property purchase at auction, usually without an inside inspection, so the research you do beforehand carries the risk.
How do I bid at the Union County tax sale?
Register before the deadline in the sale notice, which also sets the deposit, accepted payment and whether bidding is online or in person. In a deed sale, bidders compete on price, usually from a minimum set by the amount owed. Read the full terms before sale day.
Can the owner get the property back after the Union tax sale?
Mostly before the sale, not after. In a deed state the owner's protection is paying everything due before the auction, and some deed states add a short window afterwards. The New Mexico summary: The state Property Tax Division auctions delinquent parcels; sales are final with narrow challenge windows.
Is it better to buy before the Union tax sale?
Often. Before the sale the owner still holds title, so you can inspect, run title and negotiate one to one instead of bidding against the room. The catch is that a direct purchase needs the owner to agree, and many will not.
What happens to Union parcels that do not sell?
That is set by New Mexico law and stated in the notice. Unsold parcels are commonly held by the county or the state, offered again at a later sale or sold over the counter. Ask the New Mexico Property Tax Division how it handles them, because those parcels draw far less competition.
