What to know about getting a mortgage in South Carolina
South Carolina’s owner-occupied property-tax rate is among the lowest in the country — a legal-residence exemption cuts the assessment ratio to 4% — but coastal buyers give much of that back in wind and hail insurance. Off the coast, total carrying costs are some of the lowest in the Southeast.
The 2026 conforming loan limit in most South Carolina counties is $832,750 for a single-family home (designated high-cost counties go higher). Loans above that are jumbo — expect tighter underwriting and different pricing.
The borrower-quoted offers above were submitted by real South Carolina residents in the last 30 days. We score every submission for fraud signals before publishing, and verified offers carry a verified badge after we OCR the Loan Estimate.
The credit-union rates are taken from each lender's public rate sheet on the effective date shown. We don't take affiliate fees, sell contributor data, or rank lenders by commission. The full methodology is on the methodology page.

Frequently asked: mortgages in South Carolina
Straight answers, grounded in the data on this page.
What is the best mortgage rate in South Carolina right now?+
The lowest conventional 30-year rate we're tracking in South Carolina this week that anyone can join is 6.250% from PenFed Credit Union, 0.41% below the U.S. average of 6.660%. It's a real posted rate, not a teaser — your actual rate depends on your credit, down payment, and loan type. Credit unions with restricted membership (military or employer-based) sometimes post lower; those are listed below with their eligibility.
How much do you need to put down for a house in South Carolina?+
The median home price in South Carolina is about $295,000, so 20% down is roughly $59,000. Many buyers put down far less: conventional loans go as low as 3%, FHA 3.5%, and VA/USDA can be 0% for those who qualify (with mortgage insurance when you put down under 20%).
Which credit unions can South Carolina residents join for a mortgage?+
South Carolina residents can currently get posted mortgage rates from REV Credit Union, Navy Federal Credit Union, PenFed Credit Union, and others. Many credit unions let anyone join through a small one-time association membership — each one's eligibility and exact join steps are on its page.
What first-time homebuyer programs does South Carolina have?+
South Carolina's housing finance agency is the SC Housing. SC Housing’s Homebuyer Program offers fixed-rate loans with forgivable down-payment assistance up to $10,000. These programs work through participating lenders, so you can (and should) still compare the program rate against the credit-union rates on this page.
What is the conforming loan limit in South Carolina?+
For most South Carolina counties the 2026 conforming loan limit is $832,750 for a single-family home (designated high-cost counties go higher). Loans above the limit are jumbo, which typically means tighter underwriting and different pricing.
Does RatePerch take referral fees from lenders in South Carolina?+
No. We don't take affiliate or referral fees, sell contributor data, or rank lenders by commission. Borrower-quoted rates are submitted anonymously by real South Carolina residents, and credit-union rates are copied straight from each lender's public rate sheet.
