When Does Refinancing Make Sense in South Dakota?

Refinancing in South Dakota involves paying closing costs of approximately 1.5% of your loan balance to obtain a lower interest rate. The general rule: if you can lower your rate by at least 0.75–1%, refinancing is worth exploring. With South Dakota's current average rate of 6.9%, the savings depend heavily on how far rates drop from your existing loan.

The break-even point is calculated by dividing total closing costs by monthly savings. For example, if refinancing saves you $200/month and costs $4,125, you break even in 21 months (1.8 years). If you plan to stay in yourSouth Dakota home longer than that, refinancing is likely beneficial.
