The official viewer behind the Rio Grande City GIS map
For property near Escobares, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
The viewer Starr County publishes
Begin with the Starr County parcel viewer; it covers each assessed parcel from Escobares to La Grulla. When a rural tract has no street number, pan along the nearest road until the lines appear, then click inside the one you want, which applies near Roma as much as anywhere. With a lot near Escobares, the record panel normally shows the owner of record, assessed acreage, the parcel number and sometimes recent sales.
When a parcel crosses a boundary
Starr County borders Brooks County, Hidalgo County, Jim Hogg County, and Zapata County; every one of them runs a separate parcel map. Acreage along the edge near Escobares can show up in two county records, so check the adjacent map as well. For acreage around La Grulla, our state page lists each bordering county map for Texas.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements covering ground around La Grulla are kept by the County Clerk. If you're looking near Escobares, have ready the document number shown in the record panel to skip a name search.
Saving what you find
Print or screenshot the parcel near La Grulla with its ID visible, which helps later when you ask the assessor or a title company.
Getting answers from the right desk
Questions about value or the owner field for land near La Grulla belong with the appraisal district, since that office keeps the assessment data. Questions about what you can build around La Grulla need the planning or permitting office, and the answer depends on jurisdiction.
