How this ranking is calculated
We scored 11 counties in South Dakota and ranked them by capitalization rate, calculated as annual net operating income divided by median home price. Counties without both a median home price and a median rent are excluded, because cash flow cannot be estimated without both.
Every figure assumes a median-priced home rented at the local median rent, financed with 20 percent down on a 30-year loan at 6.85%, with closing costs at 3 percent of price and operating costs at 35 percent of rent. Operating costs cover taxes, insurance, maintenance, vacancy, and management.
These are modeled estimates for comparing markets, not quotes on a specific property. A real deal turns on the individual property, its condition, and the actual rent it can command. Run any market that interests you through the calculator with real numbers before you make an offer.
