SBA loan basics
Short answer
Business owners must personally guarantee SBA 7(a) loans to ensure they have a significant personal stake in the business's success and to provide an additional layer of security for the lender.
The SBA requires all owners with a 20% or greater stake in the business to provide a full personal guarantee. This policy ensures that the borrower is fully committed to the business's repayment and prevents moral hazard. It means the owner's personal assets can be pursued if the business defaults and collateral is insufficient.
If a business fails and liquidating its assets only covers 50% of an SBA loan, the lender would then pursue the business owners' personal assets (as per their personal guarantee) to recover the remaining balance, before filing a claim with the SBA for the guaranteed portion.
Insider move
Lenders rely on personal guarantees as a crucial risk mitigation tool. They carefully ensure that all required guarantors sign and understand their obligations, as a missing or invalid guarantee could severely impact the lender's ability to recover losses and the SBA's reimbursement.
