Usual here: $12,842 an acre, the middle of 64 sales of 20 acres or more over the last 24 months (middle half $10,380 to $14,989). A sale marked unusual sits well outside that; possible reasons above the usual: a house or buildings, timber or hunting ground, a building site or development land, or a neighbor paying more for the piece next door; below: a family or neighbor sale, a part interest, wooded, wet or poorer ground, no road access, or a land contract.
Buyer and seller names are public record on the state's transfer return. They load only when you tap, and are not shown to search engines. If one is yours and you want it off this site, tap Remove my name beside it.
A sale is listed when it carries a price and acres and a whole interest changed hands in a normal sale: gifts, family and related-party sales, quit claims, foreclosures and the like are left out, the same rule as Field Scout and the Farmland Atlas. Township and town are where the state places the sale; no parcel is pinned. None of this is an appraisal.
