Understanding Conventional Loan Limits

Conventional loans are mortgages that are not insured or guaranteed by the federal government. In South Carolina, the baseline loan limit for a single-unit property is $832,750. This means that if you're purchasing a home priced above this amount, you'll need to secure a jumbo loan, which typically comes with stricter qualification requirements and higher interest rates.
