Most homebuyers assume you need a down payment to buy a house. But in South Carolina, if you’re purchasing in an eligible rural or suburban area, a USDA loan could get you into a home with zero down payment — and competitive rates to boot. Here’s what you need to know about USDA loans in SC.
What Is a USDA Loan?
A USDA loan is a government-backed mortgage offered through the U.S. Department of Agriculture’s Rural Development program. Despite the name, USDA loans are available in many suburban communities — not just farmland — including areas surrounding Charleston, Columbia, Greenville, and Myrtle Beach.
USDA Loan Eligibility Requirements
| Requirement | USDA Standard |
|---|---|
| Down Payment | 0% |
| Credit Score | 640+ (most lenders) |
| Income Limit | 115% of area median income |
| Property Location | USDA-eligible rural/suburban area |
| Property Type | Single-family primary residence |
| Mortgage Insurance | 1% upfront + 0.35% annual fee |
SC Areas Eligible for USDA Loans
Many Lowcountry and Upstate communities qualify. Eligible areas near Charleston include:
- Summerville (portions)
- Goose Creek (portions)
- Moncks Corner
- St. George
- Walterboro
- Ridgeville, Harleyville, Holly Hill
Use the USDA’s official eligibility map to check a specific address. Your lender can also verify eligibility during the pre-approval process.
USDA vs. FHA vs. VA: Which Is Best?
- USDA: Best for rural/suburban buyers who meet income limits — zero down, low fees
- VA: Best for veterans/military — zero down, no mortgage insurance. See our VA loan guide for South Carolina
- FHA: Best for buyers with lower credit scores in urban areas. See our FHA loan guide for Charleston SC
Already own a home? Veterans can use the VA IRRRL requirements in South Carolina to lower their rate with no appraisal. Homeowners can also explore when it makes sense to refinance to reduce their monthly payment.
