The Harding County land market
The economy is agricultural, and land is mainly grass and ranch tracts, from smaller recreation parcels to ranches of thousands of acres. Utilities are often limited on tracts of this size, and distance to services is large, so price per acre reflects the grass and the improvements.
How South Dakota assesses agricultural land
South Dakota values agricultural land by productivity. The Department of Revenue contracts with South Dakota State University to produce a productivity or formula value, built from USDA NASS county data as an eight-year Olympic average, and each county's director of equalization then adjusts it for factors such as soil data, terrain, location, size, climate, access and obstructions, documenting each adjustment. To be classified as agricultural, land must be used primarily for farming or ranching and meet a county acreage requirement that ranges from 20 to 160 acres, though smaller parcels can qualify on income of at least $2,500 from agriculture in three of the previous five years.
A buyer should check the parcel's classification and assessed value, and ask the Harding County director of equalization how a change of use, such as building a home or subdividing, would change the assessment.
Water, access and minerals
Many ranches rely on stock wells, stock dams and rural water lines, so ask for well records and water rights. Gravel county roads can be impassable in wet weather or snow, so confirm legal access. Ask whether minerals convey and whether any grazing or wind lease applies.
