The South Carolina USDA loan guide: buy with $0 down in an eligible area
USDA loans are the most overlooked zero-down program in South Carolina. They are not farm loans, and they are not limited to very-low incomes, which is why buyers around Florence, Aiken, and the Lowcountry keep missing them. The eligible map also reaches closer to Greenville and Columbia than most people expect. This guide walks through who qualifies, what it costs, and how a South Carolina USDA purchase runs, using current USDA figures.
What is a USDA loan?
A USDA loan for a Florence or Aiken home is a zero-down mortgage guaranteed by the U.S. Department of Agriculture through its Rural Development arm, formally the Section 502 Guaranteed program. A regular South Carolina lender makes the loan and USDA backs it, which is what lets a buyer in Walterboro or Batesburg-Leesville finance 100% without the mortgage insurance a conventional low-down loan carries. It exists to bring financing to the small towns of the Pee Dee, the rural Lowcountry, and the Upstate that big banks historically underserved.
The "agriculture" in the name throws Aynor and Lexington County buyers off. You do not need land, livestock, or any farm connection in Horry or Lexington County. It is an ordinary home loan for an ordinary house in Aynor or Gilbert, just one that sits inside the USDA-eligible map.
Who qualifies for a USDA loan in the Pee Dee and Lowcountry?
South Carolina eligibility comes down to three gates, and you clear all three. The property has to be in a USDA-eligible area, which rules out the Charleston peninsula but keeps Ravenel in. Your household income has to fall within the county limit, $122,800 for most of the state. And you occupy the home as your primary residence, so a Myrtle Beach investment condo is out.
There is no first-time-buyer requirement for a South Carolina USDA loan, and no requirement that you have never owned property. USDA does expect that you do not already own a suitable home within commuting distance of the Sumter or Florence home you are buying, since the program helps people become homeowners rather than add a second house.
What are the USDA income limits across South Carolina's counties?
USDA caps household income at 115% of the area median, counting every adult who will live in the home, not only the borrowers on the loan. Across most of South Carolina that limit is $122,800 for a household of one to four people and $162,100 for five to eight, effective July 13, 2026. The Charleston-North Charleston metro carries a higher figure near $127,500, and Beaufort County near $126,650, because Lowcountry incomes top the statewide median.
That 2026 increase matters for South Carolina buyers, because many websites still show the old $119,850 figure from 2025, and some the even-older $112,450. If a lender told an Anderson or Greenwood buyer a year ago that they earned too much, the higher 2026 limits may have changed that. Check your county on the USDA income eligibility tool, or read the full breakdown on our South Carolina eligibility page.
How does USDA property eligibility work from the Upstate to the coast?
The home must fall inside the USDA-eligible map, which in South Carolina pulls out the cores of Charleston, Columbia, Greenville, Spartanburg, Myrtle Beach, Rock Hill, and Florence while keeping the surrounding countryside in. Roughly 97% of U.S. land area qualifies, and in this state that reaches from the Pee Dee tobacco belt to the Savannah River corridor near Aiken. The map runs on 2020-census data, with grandfathering that keeps many established Pee Dee and Upstate towns eligible through the 2030 census.
The practical surprise is how close the eligible line runs to the Greenville and Charleston metros. Woodruff and Gray Court sit just outside Greenville, St. George and Ridgeville just outside Summerville, and Aynor just inland from the Grand Strand, all inside the map. The only reliable check is the exact property address on the USDA property eligibility map, since a Blythewood or Cane Bay ZIP code can straddle the boundary.
What does a USDA loan cost for a Spartanburg buyer?
A Charleston or Florence USDA loan carries no private mortgage insurance. In its place are two guarantee fees that run the same in Charleston as in the Pee Dee. The upfront fee is 1.0% of the loan amount, so on a $250,000 Spartanburg-area loan it is $2,500, charged once and usually financed in. The annual fee is 0.35% of the average balance, spread across your monthly payments for the life of the loan, and both were set on October 1, 2016 and have not changed for 2026.
Put beside FHA, a South Carolina USDA loan is cheaper on both fees: FHA charges 1.75% upfront and roughly 0.55% annually on most low-down loans. Because the 1% upfront fee can be rolled in, a USDA loan on a Florence or Aiken home can finance slightly more than the appraised value, which is unusual and works in the buyer's favor. See the full breakdown on USDA vs FHA.
What credit score does USDA need for a Columbia or Charleston buyer?
USDA publishes no minimum credit score, in South Carolina or anywhere else. Its automated underwriting engine, called GUS, most reliably approves files at a 640 score, so that is the practical target for a Columbia or Charleston buyer. Below 640, a Pee Dee file moves to manual underwriting, where an underwriter documents your credit history and any compensating factors. Individual lenders can layer their own minimums on top.
On debt, the baseline ratios are 29% of gross income toward the housing payment and 41% toward total debt, which stretch further where Florence-area prices run near $178,000. GUS can approve higher ratios when a Greenville or Aiken file shows strengths like reserves or a long, clean payment history. Deferred student loans are generally counted at 1% of the balance.
How does the USDA loan process work from offer to closing?
The path mirrors any other Columbia or Charleston purchase: pre-approval, house hunting inside the eligible map, an accepted offer, appraisal, and underwriting. USDA loans add one step at the end, where after your lender approves the file it goes to the USDA Rural Development office for a final review before the clear-to-close. That review usually takes a few business days on a Sumter or Lexington County file.
Start to finish, a South Carolina USDA purchase generally closes in about 30 to 45 days, and the biggest variable is the lender. A team that runs USDA files regularly around Charleston, Columbia, and the Grand Strand keeps the final USDA review from turning into a delay, which is exactly the kind of file we close often.
USDA vs FHA vs conventional for a South Carolina buyer
USDA wins on cost and down payment when a South Carolina buyer qualifies, but the geography and income gates rule some out. FHA has no location or income limit and reaches lower credit, at a higher insurance cost, which suits a buyer inside the Greenville or Rock Hill core. Conventional rewards strong credit and lets a Charleston buyer drop mortgage insurance later. Here is the quick comparison.
| Factor | USDA | FHA | Conventional |
|---|---|---|---|
| Down payment | $0 | 3.5% | As low as 3% |
| Location limit | Eligible areas only | None | None |
| Income cap | 115% of area median | None | None |
| Upfront fee | 1.0% guarantee fee | 1.75% UFMIP | None |
| Ongoing insurance | 0.35% annual | ~0.55% annual | PMI, cancellable at 20% equity |
| Loan limit | None (repayment-based) | County FHA limits | $832,750 in most counties (2026) |
Fee figures are program fees, not interest rates or APR. USDA fees verified against USDA Rural Development; FHA and conforming figures against FHA and FHFA, current as of August 2026 and subject to change.
Common USDA myths that cost South Carolina buyers
Two beliefs disqualify South Carolina people who actually qualify. The first is "USDA is only for farms," which sends Aynor and Woodruff buyers to pricier loans for homes that were eligible all along. The second is "we make too much," usually based on the pre-2025 income limits or on counting only the borrower instead of the whole household against the $122,800 cap. Both are worth a five-minute check before a Horry or Spartanburg County buyer rules USDA out.
Frequently asked questions
How much is the USDA guarantee fee in South Carolina?
The USDA guarantee fee is the same across South Carolina: a one-time upfront fee of 1.0% of the loan amount, which a Greenville or Florence buyer can finance in, plus an annual fee of 0.35% of the balance. On a $250,000 loan near Spartanburg that upfront fee is $2,500, and both figures have held since October 1, 2016. Pages quoting a 3.5% upfront fee are citing the statutory ceiling, not what South Carolina borrowers pay.
How long does a USDA loan take to close in South Carolina?
A USDA purchase in South Carolina typically closes in about 30 to 45 days, similar to an FHA or conventional file. The one added step is a final review by USDA's Rural Development office after your lender approves the loan, which usually adds a few business days. A lender that closes USDA files regularly around Columbia, Charleston, and the Pee Dee keeps that review from becoming a delay.
Is there a maximum USDA loan amount in South Carolina?
No. The USDA Guaranteed program sets no maximum loan amount in South Carolina, so a Charleston-area buyer is bounded by what household income supports under the debt-to-income guidelines plus the appraisal, not a county cap. That matters where Charleston prices near $489,000 push past FHA's local limit. The area loan limits people read about apply only to the separate Section 502 Direct program.
Can you refinance a USDA loan in South Carolina?
Yes, but only an existing USDA loan can be refinanced through USDA, so a Greenville homeowner cannot move a conventional or FHA loan into USDA. The USDA Streamlined-Assist refinance requires the loan to be at least 12 months old and must cut the principal-and-interest by at least $50 a month, and for most South Carolina borrowers it skips a new appraisal, credit check, and income review.
What property types qualify for a USDA loan in South Carolina?
USDA finances existing single-family homes, new construction in a Nexton or Cane Bay subdivision, condos and planned-unit developments, and new manufactured homes titled as real property. The home must be an owner-occupied primary residence in good repair, so a Myrtle Beach rental does not qualify. Existing manufactured homes on a Horry County lot are generally ineligible unless already carrying a USDA loan.
