SBA loan basics
Short answer
The government's guaranty means the SBA promises to reimburse the lender for a percentage of the outstanding loan balance if the borrower defaults, reducing the lender's risk and making them more willing to lend.
The SBA guaranty is an agreement between the SBA and the lender. It does not mean the borrower is relieved of their obligation to repay the entire loan. It simply shifts some of the default risk from the lender to the SBA, enabling lenders to approve loans that might otherwise be too risky.
A bank makes a $500,000 SBA 7(a) loan with a 75% SBA guaranty. If the borrower defaults and the outstanding balance is $400,000, the SBA would reimburse the bank $300,000 (75% of $400,000) after the lender's liquidation efforts.
Insider move
Lenders rely on the guaranty for risk mitigation but must adhere strictly to SBA rules during origination, servicing, and liquidation to ensure the guaranty remains valid and is honored by the SBA.
