SBA loan basics
Short answer
The government 'guaranty' means the SBA promises to reimburse the lender for a percentage of the loan amount if the borrower defaults. This reduces the lender's risk, making them more willing to lend.
The SBA guaranty protects the lender, not the borrower. If a borrower defaults on an SBA 7(a) loan, the SBA will pay the lender for the guaranteed portion of the outstanding balance. This mechanism encourages lenders to provide financing to small businesses that might be deemed too risky for conventional loans without such a guaranty.
A bank issues a $100,000 SBA 7(a) loan with a 75% guaranty. If the borrower defaults and the bank recovers only $10,000, the SBA will pay the bank $67,500 (75% of the remaining $90,000 loss).
Lenders must follow all SBA rules for loan origination, servicing, and liquidation to ensure the guaranty remains intact. Failure to do so can result in the SBA reducing or denying the guaranty claim.
