When Refinancing Makes Sense in South Carolina
Refinancing replaces your current mortgage with a new one — ideally at a lower rate or shorter term. The key question is whether monthly savings recoup closing costs before you move.
Check Your Break-Even
Divide closing costs by monthly savings. Under ~24 months is generally worthwhile. Use the break-even calculator.
Compare Credit Unions
Credit unions in South Carolina often undercut bank refi rates by 0.25–0.50%. Compare at least 3–5 lenders.
Mind Your LTV and Credit
Lower loan-to-value and a score above 740 unlock the best refinance pricing. Cash-out refis price higher than rate-and-term.
Weigh Term Changes
Refinancing into a 15-year term raises the payment but cuts total interest. A shorter term often carries a lower rate.
