SBA loan basics
Short answer
The SBA acts more like an insurance provider for the lender rather than a co-signer for the borrower, guaranteeing a portion of the loan to the bank.
A co-signer is equally liable for a debt, but the SBA's role is to partially reimburse the lender if the borrower defaults. This reduces the lender's risk, encouraging them to make the loan, but the borrower remains 100% responsible for repayment.
If a borrower defaults on a $500,000 SBA loan with a 75% guaranty, the SBA pays the lender 75% of the unrecovered loss, not 75% of the entire loan. The borrower is still pursued for the full amount.
