SBA loan basics
Short answer
The 'SBA guarantee' primarily protects the lender, not you directly, by covering a portion of the loan if you default. You, the borrower, are still fully responsible for repaying the entire loan.
The SBA guarantees a percentage of the loan amount (up to 85% for loans under $150,000 and up to 75% for loans over $150,000) to the lender. This reduces the lender's risk, making them more willing to approve loans for small businesses. However, the borrower remains legally obligated to repay the full debt.
If a business defaults on a $500,000 SBA 7(a) loan, the lender will first try to collect from the business and its guarantors. If they recover only $100,000, the SBA will then pay the lender a percentage of the remaining $400,000 outstanding balance (e.g., 75% or $300,000), but the borrower is still liable for the entire original $500,000.
Insider move
Lenders understand the guaranty reduces their exposure but still require strong underwriting to ensure the loan is collectible. They rely on the borrower's commitment and collateral to minimize the need to call on the guaranty.
