SBA loan basics
Short answer
For you, the borrower, the 'SBA guarantee' means a private lender is more likely to approve your loan application and offer better terms because the SBA reduces the lender's risk of loss if you can't repay.
The SBA guarantee protects the lender, not the borrower. If a borrower defaults, the SBA reimburses the lender for a portion of the outstanding balance. This encouragement for lenders translates into more accessible and affordable loans for small businesses.
A bank lends $500,000 to a business with an 85% SBA guarantee. If the business defaults and the bank recovers only $100,000 from collateral, the SBA will pay the bank 85% of the remaining $400,000 ($340,000).
Insider move
Lenders rely on the guarantee, but must follow all SBA rules for loan origination and servicing to ensure the guarantee remains valid. Any non-compliance can lead to a 'repair' or denial of the guarantee claim.
