SBA loan basics
Short answer
A personal guarantee means that you, as an owner, are personally responsible for repaying the loan if your business cannot. It provides an additional layer of security for the lender.
The SBA requires all owners with 20% or more equity in the business to provide an unconditional personal guarantee. This ensures that the principals have a vested interest in the business's success and provides the lender with recourse beyond just the business's assets if the loan defaults.
If your business defaults on a $300,000 loan, and you have a personal guarantee, the lender can pursue your personal assets, such as savings or non-retirement investments, to recover the outstanding debt after liquidating business assets.
Lenders view personal guarantees as crucial for reinforcing borrower commitment and mitigating risk. They ensure all required owners sign the guarantee to protect the enforceability of the loan agreement.
