Question 2

What is the South Dakota housing market like?

Accepted Answer

South Dakota's housing market is anchored by Sioux Falls, the state's economic hub. Sioux Falls has seen steady price growth driven by financial services sector growth (credit card companies and banks choose South Dakota for its regulatory environment). Rapid City serves the western part of the state near Mount Rushmore and the Black Hills. No state income tax is a significant draw for buyers.
