When an ARM May Make Sense in South Carolina
- You plan to sell or refinance within 5-7 years
- You're buying in a high-cost South Carolina 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 Carolina
- You plan to stay long-term (10+ years)
- Payment certainty matters more than short-term savings
- South Carolina's property taxes (0.57%, avg $1,322/year) add enough payment variability without adding rate risk
