Bon Homme County lies along the south border of South Dakota (adjacent to Nebraska via the Missouri River). Created 1862 and named after “Bon Homme” Island (from French “good man”), referenced by Lewis & Clark. The county seat is Tyndall, South Dakota, and other key towns include Springfield, South Dakota and Scotland, South Dakota. Agriculture dominates—rolling hills sloping toward the Missouri River valley; low population density (~12.4 persons per square mile in 2020) reflects the rural character. Most homes are detached single-family houses on modest town lots or farm homes on acreage. Homes for sale in recent data show median listing price ~ $166,000 (Aug 2025) and typical home-value index ~$171,000. Land listings (farms/ranches) average ~$184,000 (for large acreage) though of course farms are much higher. If building a custom home on a parcel you might expect ~$200K-$350K depending on lot size and improvements; for acreage perhaps $400K+. Nearest significant city: to the east lies Yankton, South Dakota (regional hub) ~30-40 miles. Because of its border location and river valley terrain, there may also be recreational/lake-front housing in parts. Overall: rural-dominated county, modest home prices, substantial farmland and land-buying potential.
