In short
A principal guarantor is an owner of 20% or more of the business who must personally guarantee the SBA loan. This means your personal assets are on the hook if the business defaults.
As a buyer, if you own 20% or more, you will be a principal guarantor. Understand the full extent of this personal liability, including any spousal guarantees. This is a core requirement of the SBA 7(a) loan, so be prepared to sign the personal guarantee.
