South Dakota variant. This is a South Dakota-specific version of the Refinance Calculator, using pre-defined local figures (tax rates, median home and income values, and typical regional costs). For the full formula, methodology, and FAQ, open the main Refinance Calculator.
Refinancing a South Dakota mortgage makes sense when the monthly interest savings recover your closing costs before you sell or move. On the state's $290,000 median home, even a small rate drop moves real money.
When refinancing pays off in South Dakota
Closing costs typically run 2-5% of the loan balance. On a $232,000 loan (80% of the $290,000 median home), that's roughly $6,960 at 3%.
Your break-even point is closing costs ÷ monthly savings. Drop your rate enough to save $200/month and you'd recover $6,960 in about 35 months - refinance only if you'll stay past that point.
