South Carolina Mortgage Calculator
South Carolina has a low property tax rate (~0.57%) — among the lowest in the country — but coastal insurance premiums run higher.
South Carolina's effective property-tax rate runs around 0.57%, among the lowest in the country. Median home values near $290,000 keep tax bills modest. Hurricane risk on the coast drives slightly elevated insurance premiums, but inland markets remain competitive. Charleston and Greenville buyers often use conventional conforming or FHA; VA is common near Charleston AFB, Fort Jackson, and Shaw AFB.
Mortgage Calculator
How Mortgage Calculations Work
Loan Amount
We calculate the principal by subtracting your down payment from the home price.
Monthly Payment
Using the loan amount, interest rate, and term, we calculate your fixed monthly payment.
Amortization
Each payment is split between principal and interest, with early payments going more toward interest.
What factors affect your mortgage payment?
- Home Price: The total purchase price of your property
- Down Payment: Large down payments reduce your loan amount and monthly payment
- Interest Rate: Higher rates mean higher monthly payments and more total interest
- Loan Term: Longer terms have lower monthly payments but more total interest
