Credit Score Needed for a Conventional Loan in South Carolina
Reviewed by the HomeMath editorial team Updated 2026-08-06
Key takeaways
- Minimum credit score for a conventional loan in South Carolina is typically around 620.
- A score of 660 or higher is often required for low‑down‑payment conventional options (e.g., 3% down).
- Scores of 720 or above usually qualify for the most competitive interest rates.
Conventional mortgages are private‑sector loans that aren’t insured or guaranteed by the government. Lenders rely heavily on your credit score to gauge repayment risk, so the score you present directly influences both eligibility and pricing.
Why a minimum score matters
Most conventional lenders set a floor at about 620 because scores lower than that indicate a higher likelihood of default. Below that threshold, borrowers may be steered toward government‑backed programs such as FHA or VA loans, which have more flexible credit requirements.
Better scores get better terms
Even after meeting the minimum, your exact score determines the interest rate spread you’ll receive. Lenders typically reserve their lowest‑rate brackets for borrowers with scores of 720 or higher, rewarding the reduced risk with lower monthly payments.
Low‑down‑payment options
- Three‑percent down conventional loans usually require a score of at least 660.
- Five‑percent down options often start at a 620‑640 score range, but rates may be higher.
South Carolina specifics
- Many SC transactions close with a real‑estate attorney, which can add an extra layer of review on financing documents.
- The SC Home Advantage program helps first‑time homebuyers, but participants still need to meet conventional credit score minimums (generally 620) to qualify.
Improving your credit before applying—by paying down balances, correcting errors, and avoiding new debt—can move you into a better rate tier.

FAQ
Can I get a conventional loan with a credit score below 620 in South Carolina?
Most conventional lenders set 620 as the baseline. Scores below that usually push borrowers toward FHA, VA, or USDA loans, which have lower credit thresholds.
How does my credit score affect the interest rate I’ll receive?
Lenders assign borrowers to rate buckets. Higher scores (720+) qualify for the lowest rates, while scores closer to the minimum (620‑660) are offered higher rates to offset perceived risk.
Do South Carolina first‑time‑buyer programs have separate credit score requirements?
Programs like SC Home Advantage still require you to meet the conventional loan’s minimum credit score, typically 620, though they may offer assistance with down payments and closing costs.
What steps can I take to improve my credit score before applying?
Pay down revolving balances, keep credit utilization under 30%, dispute any inaccurate items on your reports, and avoid opening new credit lines in the months leading up to your application.
Are there different credit score thresholds for jumbo conventional loans in South Carolina?
Jumbo loans, which exceed conventional loan limits, often require higher scores—generally 680 or above—because the loan amounts are larger and present more risk to lenders.
