South Carolina Mortgage Calculator

South Carolina taxes an owner-occupied home very differently from a rental or second home. A primary residence is assessed at 4% of value, while other residential property is assessed at 6%. That keeps the effective rate for owners low, around 0.45%. Buyers moving in from other states should file for the 4% rate right away, because without it the first bill is much higher.

Homestead exemptions and property tax relief

To get the 4% legal residence rate, apply to the county assessor with proof of domicile, such as an SC driver's license, vehicle registration and voter registration at the address. The deadline is generally January 15 of the following year.

First-time buyer programs

SC Housing's Palmetto Heroes program offers $10,000 of forgivable assistance for teachers, first responders, health care workers, military members and veterans, but it is closed for 2026. SC Housing's standard homebuyer program and its assistance remain available through participating lenders.

Transfer and recording taxes

The deed recording fee is $1.85 per $500 ($1.30 state, $0.55 county), about $1,108 on a $299,500 home, and by custom the seller pays it.

Closing costs to plan for

South Carolina requires an attorney to close. Buyer costs are attorney, lender and title fees plus prepaids; coastal homes add a wind or flood policy.

When property tax bills are due

South Carolina counties mail tax bills in the fall, and the first penalty date is typically January 15. Owner-occupied homes are assessed at 4% of value and most other property at 6%, so the classification can raise the bill by half. Escrow is usually set up assuming the 4% rate, so make sure you get it.

Before you buy in South Carolina

The 4% legal residence rate is not automatic. Apply with the county assessor before the first penalty date, usually January 15, for the year you first claim it. You must own and occupy the home as your legal residence and domicile, and up to five contiguous acres qualify. If you miss it, the home is billed at 6% as a second home or rental would be. Most counties ask for a South Carolina driver's license and vehicle registration at the address.

FHFA 2026 one-unit conforming limits: no county is high-cost, so $832,750 applies statewide. So $239,600, the 80% loan on a median home, needs no jumbo financing.
