Records to check before you buy in Doña Ana County

• Property record card — the Doña Ana County assessor / appraisal office. Pull the parcel's assessed-value history, exemption status, and last sale. This is the file your future tax bill is calculated from, and it shows whether the current owner is enjoying exemptions you will not inherit. County government sits in Las Cruces — start there for office locations and the parcel search.
• Deeds & liens — the Doña Ana County recorder / land-records office. Read the deed chain, open liens, easements, and plat maps — the file a listing never mentions.
• Official flood determination. Check the exact parcel on FEMA's National Flood Hazard Layer — not the listing site's licensed model. Zone boundaries cut through streets; the house next door can be in a different zone. Doña Ana County is the primary county for 23 ZIP codes in the Census Bureau's ZIP-to-county crosswalk — and zone lines ignore every one of them.
• The county's reported-crime record. In the FBI's 2024 file, agencies in Doña Ana County reported 8,403 offenses — 36.64 per 1,000 residents; the largest single category was larceny-theft (4,864). The crime section below sets that beside the New Mexico county median.
• Registry check. Run the address through the official New Mexico registry and note the counts within a mile — then check again the week you close.
• Permits & code history — the Doña Ana building department. Open permits, expired permits, and code cases tell you whether the renovation in the photos was ever inspected. County permitting is run out of Las Cruces.
• School assignment — the district office, not the listing. Only the district's own boundary lookup confirms which school an address is actually zoned for.
