The 8 most affordable cities in South Dakota to buy a house

Homeownership is fundamental to the American dream. It offers wealth, security, community, and countless other benefits. Yet for many South Dakota residents, the dream feels increasingly out of reach—even as incomes rise and mortgage rates fall. Near-record prices have made homes hard to come by and often even harder to afford, leaving buyers and sellers stuck and younger generations priced out.

But affordable pockets still exist. In cities across the state, residents can comfortably spend around 30% of their income or less on housing, which is widely considered the affordable threshold.
