How to Read South Carolina Mortgage Rates
South Carolina is not one uniform mortgage market. The rate table below covers 82 cities, but the real payment difference comes from home price, income, property taxes, loan size, and whether a borrower fits conventional, FHA, VA, or jumbo pricing. Use this page to compare cities first, then use lender quotes for final APR and fee decisions.
- At the state-average payment of $1,235 per month and median income of $52,623, South Carolina looks close to the traditional affordability line for many households.
- The observed city-level 30-year benchmark spread is 0.57 percentage points, from 6.33% to 6.9%. Even small rate differences matter more in expensive cities because they apply to larger loan balances.
- Average property-tax pressure is relatively low, so purchase price and rate lock timing usually drive more of the monthly-payment difference.
- For buyers comparing down payment choices, pair this state page with the PMI calculator, affordability calculator, and closing cost estimator before assuming the lowest advertised rate creates the lowest total cost.

South Carolina Mortgage Quote Comparison Worksheet
Use this checklist before choosing between lender quotes, state assistance, builder credits, or a temporary buydown. It is built to catch the costs that do not show up in a simple rate table.
| Line Item | What to Compare |
|---|---|
| Rate vs APR | APR exposes points, lender fees, and credits that can hide inside a lower advertised rate. |
| Cash to close | Compare down payment, closing costs, prepaid taxes, insurance escrow, and any assistance or seller credit. |
| Payment after escrow | South Carolina buyers should compare principal, interest, property tax, insurance, HOA or condo dues, and mortgage insurance together. |
| Assistance terms | Down payment assistance can be a grant, forgivable second, deferred second, or repayable loan; the repayment rule changes the real cost. |
| Rate lock and buydown | Temporary buydowns and lender credits can improve the first-year payment while leaving a higher long-run payment. |
A strong South Carolina mortgage comparison should include at least two lender Loan Estimates plus one program or assistance check where available. Pair this worksheet with the affordability calculator, PMI calculator, and closing cost estimator.
South Carolina SC Housing, Coastal Insurance & DPA Notes
South Carolina borrowers should compare mortgage-rate benchmarks with SC Housing assistance, coastal insurance, flood-risk assumptions, USDA eligibility, and the price gap between Charleston, Greenville, Columbia, Myrtle Beach, and smaller markets.
- SC Housing provides homebuyer program and assistance information for eligible South Carolina buyers through approved lending channels.
- Down payment assistance can change cash-to-close, but borrowers should compare APR, mortgage insurance, fees, assistance terms, and full escrow.
- Coastal South Carolina purchases can require extra attention to wind, flood, HOA, condo, and insurance assumptions.
- USDA eligibility can matter in smaller or rural South Carolina markets, but property and income rules are separate from the rate benchmark.
