SBA loan basics
Short answer
When the SBA "guarantees" a loan, it means the SBA promises to pay a portion of the outstanding loan balance to the lender if the borrower defaults.
The SBA guarantee is an agreement between the SBA and the lender, not directly with the borrower. It reduces the risk for the lender, encouraging them to make loans to small businesses they might otherwise consider too risky. This guarantee does NOT mean the borrower is off the hook for repayment; the borrower is still fully responsible for the entire loan amount.
A bank makes a $100,000 SBA 7(a) loan with an 85% guarantee. If the borrower defaults and the outstanding balance is $80,000, the SBA will pay the bank 85% of that amount ($68,000) after liquidation efforts.
Insider move
Lenders must follow all SBA rules and guidelines meticulously to ensure the guarantee remains valid. Failure to do so can result in the SBA reducing or denying its guarantee payment if the loan defaults.
