SBA loan basics
Short answer
For an SBA 7(a) loan, any individual owning 20% or more of the business is required to provide an unlimited personal guarantee.
The SBA mandates that all owners holding at least a 20% equity stake in the applicant business must provide an unconditional personal guarantee. This ensures that a substantial portion of the ownership group is personally committed to the success and repayment of the loan, regardless of the availability of business collateral.
If a business has three owners with stakes of 50%, 30%, and 20%, all three would be required to sign an unlimited personal guarantee for an SBA 7(a) loan. If another owner only had 15%, they would not be required to guarantee.
Insider move
Lenders meticulously identify all owners and verify their ownership percentages. They ensure all required personal guarantees are properly executed and documented, as this is a fundamental requirement for the SBA guarantee to be valid.
