When an ARM May Make Sense in South Dakota
- You plan to sell or refinance within 5-7 years
- You're buying in a high-cost South Dakota market where even a small rate reduction meaningfully lowers payments
- Rates are at cyclical highs and expected to fall — ARM initial rates can be 0.5-1% lower than fixed
When Fixed Rates Win in South Dakota
- You plan to stay long-term (10+ years)
- Payment certainty matters more than short-term savings
- South Dakota's property taxes (1.14%, avg $2,447/year) add enough payment variability without adding rate risk
Closing Costs
Either product incurs similar closing costs (~$2,600 in South Dakota). Frequent refinancing to escape an ARM adds these costs repeatedly.
