How to check any New Mexico parcel yourself, for free

Owner, acreage, boundary, taxes, deeds and zoning — every record is public. Here is where each one lives and how to read a legal description.

Everything a title company checks about a piece of land is a public record you can read yourself. Here is where.

Start with the parcel number

Called the UPC in New Mexico. It is on the tax bill, on the assessor's site, and at the top of every one of our listings. Have it before you call anyone.

The assessor: who owns it and what it is

Every county assessor has a property search, most with a map. Look up the UPC and you get the owner of record, the mailing address for the tax bill, the acreage, the legal description, and the assessed value. If the owner shown is not the person selling, stop and ask why. A recent sale can take weeks to show; an answer of "it's being recorded" should come with a recording number you can check with the clerk.

The treasurer: are the taxes paid

The treasurer's search shows the yearly bill and whether it has been paid. Taxes stay with the land: buy a lot with three years owing and you owe them. Land more than three years delinquent can be sold by the state at public auction, which is how some resellers, us included, acquire lots.

The clerk: the deeds

The county clerk records deeds, contracts, easements and liens. Many counties have online indexes; some still want you at the counter. Search by owner name and by legal description. You are looking for the deed that gave the current owner the land, and for anything recorded against it since.

Planning and zoning: what you may do

A phone call. Give them the UPC and ask the exact question: "May I place a manufactured home on this lot?" "Do I need a permit for a shed?" "What is the minimum lot size for a septic system here?" Write down who told you.

Reading a legal description

Two kinds. A platted subdivision lot reads like "Rio del Oro Unit 12, Block 4, Lot 7" — the plat on file with the clerk draws every lot and every road. Unplatted land is described by the Public Land Survey System: "the NE quarter of the SW quarter of Section 14, Township 6 North, Range 3 East" — a 40-acre square inside a one-mile section, located by township and range from a base line. The county GIS map draws both.

The map is not a survey

The boundary on the assessor's map is drawn from the description and can be off by yards. Only a licensed surveyor setting corners on the ground tells you exactly where the land is. For a fence, a well or a building on a small lot, that matters; for forty acres of grazing, usually less.

State records worth knowing

The Office of the State Engineer has every recorded well, with depth and water level, on a public map. The Environment Department issues septic permits. The Property Tax Division publishes the notices of upcoming delinquent-tax auctions.
