SBA loan basics
Short answer
The SBA requires personal guarantees from all owners of 20% or more to ensure their personal commitment to the business's success and repayment of the loan. This motivates owners to prevent default.
A personal guarantee ensures that the principals of the business have a personal stake in the loan's repayment, beyond just the business assets. This commitment significantly reduces the risk of default for both the lender and the SBA. The guarantee is typically unlimited, meaning the guarantor is liable for the entire loan amount.
If a business defaults on an SBA 7(a) loan, and the business assets are liquidated for $100,000, but $300,000 is still owed, the bank will then pursue the personal assets of the owner who signed the guarantee to recover the remaining debt.
