For land around Kent, a quick Union County land owner map lists who the tax bill goes to. Covered here for this county: where to search, what trusts, estates and LLCs mean, and how to confirm with the deed around Afton.
Getting started with the Union County land owner map
Use the Union County Beacon site for a Union County land owner map; search by address, owner name or parcel ID.
The free map to start with
Your first stop is the Union County Beacon site; it maps each tax parcel from Afton to Thayer. If you only know roughly where the land is, follow the nearest road on the aerial until the lines appear, then click inside the one you want, which applies near Cromwell as much as anywhere. On ground around Cromwell, copy the parcel ID from that panel; each clerk in the county uses it to find the file.
Tax data in the record
The record for a parcel near Lorimor often lists value and tax amounts; the County Assessor sets values and the treasurer or collector bills taxes.
The paper trail behind a parcel
On ground around Shannon City, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county are kept by the County Recorder. For a parcel near Talmage, have ready the instrument number from the tax record and the lookup takes minutes.
Trusts, estates and LLCs
For a home near Afton, the owner field shows who the tax bill names, sometimes a trust or LLC. "Estate of" on a record near Shannon City often points to an open probate, so the personal representative is the contact.
Deeds behind the record
For a home near Kent, a viewer entry isn't legal proof; deeds filed with the County Recorder are what count.
A quick look at the area
Creston serves as the county seat, home to the main records offices. Smaller places on the map include Afton, Arispe, Cromwell, and Lorimor, where town lots give way to larger tracts. Around 11,906 people live in Union County (Census estimate, 2023) across some 424 square miles. The county was organized in 1851, and some chains of title near Lorimor are long.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Kent, though signal can drop in rural spots. A saved image of the lot near Arispe and its lines is a good backup.
Which office to call
Questions about value or the owner field for land near Cromwell belong with the County Assessor, since that office keeps the assessment data. Zoning, permits and septic questions near Lorimor are for the local planning and health departments, town or county, depending on location.
Contacting an owner politely
A polite note sent to the tax-bill address is the usual way to reach an owner for property around Afton.
How land is described here
Iowa follows the Public Land Survey System, which means a tract near Kent is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Talmage odd-sized. Keep the legal description for land near Creston for any title or survey request.
Looking around the parcel
Click the parcels around the one near Creston to see who owns the neighboring land; it helps with access and boundary questions.
Limits of the parcel data
If the land is near Thayer, listed acreage is a tax-roll number; only a licensed surveyor establishes the real boundary on the ground. Out toward Afton, records update in batches, so a deed recorded last month can take weeks to appear.
Neighboring parcel maps
Union County borders Adair County, Adams County, Clarke County, Decatur County, and Madison County, and each of those keeps its own parcel map. A tract near the line by Thayer may be split in two county records, so look at the neighboring map before you assume the acreage. For acreage around Kent, our state page links each bordering county map for Iowa.
