Planning a purchase in South Carolina
The prefilled price, tax percentage, and interest rate are illustrative inputs, not verified South Carolina averages or lender quotes. Replace them with the property's price, a local tax estimate, an insurance quote, and your lender's rate.
Do not enter the legal residence assessment ratio as a tax rate
South Carolina’s special 4% assessment ratio for a qualifying legal residence is applied to property value before local tax calculations. It is distinct from the homestead exemption and requires an application with the county assessor. It is not a 4% annual tax bill.
For your estimate: Obtain a tax estimate reflecting approved legal residence status. Convert that annual dollar amount to an effective percentage of your purchase price for the calculator’s tax field.

SC Housing lists forgivable down payment assistance with its homebuyer program, with no interest or monthly payments under the program terms. Income and purchase price limits vary by county, so a property’s location affects more than its tax estimate.
For your estimate: Confirm current county limits, funding and forgiveness conditions with a participating lender. A conditional assistance benefit should not be treated as unrestricted cash or deducted from the home’s price.

Using local estimates in this tool
The tax field multiplies the home's price by a percentage. If your assessor estimates an annual tax bill, divide that bill by the entered home price and multiply by 100. Do not enter an assessment ratio or millage directly. For example, an illustrative $4,800 annual bill on a $400,000 price corresponds to 1.2%; these are not local averages.
This payment includes principal, interest, property tax and home insurance. Budget mortgage insurance, HOA dues, maintenance and closing costs separately.
Official resources and next steps
HUD housing and homeownership resources for South Carolina provides further counseling and housing contacts.
For FHA financing, use HUD's county and unit-count lookup. Select South Carolina, the property's county, the calendar year, and the number of units. The 2026 national one-unit floor of $541,287 is a baseline, not a determination of the limit for every county in South Carolina.

How to Use This Mortgage Calculator in South Carolina
Enter the price of the property you are considering in South Carolina, then adjust the down payment and rate. The payment combines principal, interest, property tax, and insurance. It does not include HOA dues, maintenance, or mortgage insurance.
For example, at the illustrative price of $287,000 and 6% down, the base loan is $269,780. These are calculation examples, not a statement about prices or typical buyers in South Carolina.
Compare the same home under different rates and down payments. A lower monthly payment from a longer term can still mean more lifetime interest. Confirm taxes and insurance for the property before relying on the estimate.
