Finding Union County land for sale on the parcel map

Union County publishes its parcels on the Union County Beacon site, which runs on Schneider Geospatial's Beacon platform, free to use for a lot in Cromwell or a parcel near Thayer. In the county version, the search page takes an owner, an address or a parcel ID, and each report links back to the map view for the parcel near Cromwell. Our Union County, IA page keeps the official link and the maps next door to Thayer in one place.

Deeds and plats behind the Union County map

Due diligence on Union County land
Start with access for a parcel near Cromwell: check road frontage on the map, and read the deed for any access easement. Then check FEMA's Flood Map Service Center for any part of the parcel near Creston that sits in a mapped flood zone. Ask the county or town office in Creston what permits a homesite would need, then price power and water for the county tract.
The lay of the land around Creston
From Creston, the seat of the county, the map spreads out to Afton, Arispe, Cromwell, and Lorimor. Smaller places such as Talmage and Kent appear on the county map as little clusters of lots. Census Bureau estimates put Union County at about 11,906 residents in 2023 on about 424 square miles of land. Outside Cromwell, most of the county map is farm, ranch or timber ground with large, irregular tracts. With a founding date of 1851, Union County has long chains of title on some rural tracts.
What the surrounding parcels tell you
The Union County record shows assessed value and taxes, which help you budget the carrying cost of land near Talmage. Look at the neighbors, too: who owns the tracts around a parcel near Creston tells you a lot about what may happen next door.
What the map won't show
Timber, crops and pasture on a parcel near Afton affect value and taxes, so walk the ground and ask what the county classification is. Check cell coverage and internet options at the parcel near Creston well before you plan to live or work there.
Before you buy in Union County
Unlisted acreage near Talmage sometimes sells to whoever asks first; the county parcel map gives you who to ask. A title company and a licensed land surveyor finish what the county map starts on a parcel near Talmage.
Union County vacant land questions
Can I buy Union County land that isn't listed?
Sometimes; the landowner of a parcel near Talmage may sell if asked, and the county record gives the mailing address.
Why does a listing near Shannon City show different acreage than the map?
No, it is an assessed figure; a licensed survey sets the acreage you pay for near Shannon City.
How can I track down open lots near Cromwell?
Scan the Union County Beacon site with aerial imagery on and click tracts near Cromwell with no buildings and no improvement value.
Can I build on vacant land in Union County?
For the lot near Cromwell, check zoning, road access and the flood map first, each handled by a different office in the county.
How do I tell if land near Shannon City is landlocked?
Not always; on a county tract, confirm frontage or a recorded easement; no frontage and no easement can mean no legal access near Shannon City.
