Union County by land and water

The Census records 2.15 square miles of water within Union County, or 0.5% of its total area. That share is close to Union County’s 0.5%. This is geographic context; waterfront status and usable land must be checked at the parcel.

For scale, Union County has 421.1 times the land area of nearby Afton city (1.01 square miles). These areas describe boundaries, not comparable property prices.

The Census boundary meets Adair County, Adams County, Clarke County, Decatur County, Madison County, Ringgold County, Taylor County within Iowa. A tract near one of these lines should be matched to the county identifier on its own records.

FROM LOCAL CONTEXT TO YOUR PARCEL

Three questions for
Union County land.

These starting questions follow this location’s jurisdiction, regional setting, and nearby geography. The answers come from the property itself.

01

Locate the parcel within Union County

Use a tax bill, deed, or assessor’s parcel number to pin down the land in Union County. The county includes 8 listed community geographies; a nearby community name does not prove the parcel is inside its limits.

02

Read the Rolling Loess Prairies setting

Rolling Loess Prairies belongs to Western Corn Belt Plains. Is the parcel on a till plain, loess hill or valley edge, and what existing drainage and access documentation is available? The wider county also reaches Central Irregular Plains; use the parcel’s location to choose the relevant setting.

03

Check the route, beyond Afton

Afton is 2.6 miles east of the Union County reference point. That geographic proximity does not establish a drivable route or legal access. Which road reaches your land, and is the right to use it recorded?

Your Union County
land questions.

Have a tax bill, an inherited deed, or simply a map pin? Start with what you have.

What should I send for land in Union County?+

Send the parcel number or legal description, approximate acreage, and a map pin showing the property in Union County. Union County’s 423.6 square miles of land include many different property situations; the exact parcel is what we review.

Does Rolling Loess Prairies describe all of Union County?+

The county’s mapped footprint intersects 2 regional units; Rolling Loess Prairies is the largest mapped share. County-scale information cannot establish the soil, slope, drainage, or development potential of one tract.

Can I use Afton as a reference for my land?+

It can help explain the location: its Census point is about 2.6 miles east of Union County’s. That distance is not a driving route, utility connection, or comparable-sale adjustment. Share the actual access road and parcel records so we can review your property on its own facts.

Can I request an offer without being near Union County?+

Yes. Begin online with the property location and ownership details. Tell Larry G and the team what you know about the land, access, and any co-owners. We review the parcel before deciding whether to propose a purchase; if a sale moves forward, the closing company can explain remote signing arrangements.
