Finding a lot on the Van Alstyne GIS map
Parcel maps here are usually run by the county, not the town, and for Van Alstyne that means the Grayson CAD interactive map.
The free map to start with
Lots and tracts near Sherman can be looked up on the Grayson CAD interactive map, free to use and open without a login. If the land is near Southmayd, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near Southmayd, the record panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Grayson County in a few facts
Sherman is the county seat, home to the main records offices. Other places on the map include Howe, Tom Bean, Dorchester, and Gunter, each with its own cluster of lots. About 146,907 people live in Grayson County (Census estimate, 2023) across some 933 square miles. Grayson County was formed in 1846, and some chains of title near Southmayd are long. Landmarks such as Hagerman National Wildlife Refuge make handy reference points on the map near Dorchester.
A word on accuracy
Tax maps are drawn for assessment, not measured on the ground, so a fence near Gunter often sits some distance off the line on screen. For a parcel near Tom Bean, records update in batches, so a deed recorded last month might lag behind.
Van Alstyne and the county around it
Van Alstyne sits in Grayson County, Texas, so its parcels are on the county's map. Local government in the town handles things like zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records, especially near Denison. Lots just outside the city limits out by Gunter often follows county rules, not municipal ones.
Three ways to find a parcel
Vacant ground near Dorchester may lack an address, so zoom in from the nearest road and click the outline. For acreage around Howe, a parcel ID is the most reliable search, and it's printed on tax bills.
Beyond the parcel lines
For a home near Gunter, layer lists often include municipal boundaries, floodplain and sometimes zoning; availability varies.
Offices that can help
Questions about value or the owner field for land near Tom Bean are handled by the appraisal district, since that office keeps the assessment data. Questions about what you can build around Sherman go to planning, building or health offices, depending on whether the land is inside town limits.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Howe sit with the County Clerk. Long-held tracts around Gunter may trace back through several deeds, and a title company earns its fee on a real sale.
Sections, lots and bearings
Tracts outside towns near Tom Bean commonly use metes-and-bounds descriptions, which trace the boundary call by call. Platted lots around Sherman usually use lot and block from a recorded plat instead, making them easier to find. Keep the legal description for land near Gunter before you request a deed or survey.
Inside the parcel card
Recent sales on nearby lots in Van Alstyne are a useful starting point; an appraiser is the real authority.
Keeping a record
