Who runs this map
This is a statewide map, not a county site. NM Office of the State Engineer County Parcels 2025 layer (ArcGIS Map Viewer) covers parcels across New Mexico, and Otero County is one part of it. Statewide parcel layers are usually stitched together from county files, so the newest splits or sales may show up on the county's own records first. When we tested the link in October 2026 it opened with no login and no fee.
