SBA loan basics
Short answer
Typically, only owners with 20% or more equity in the business are required to sign a personal guaranty for an SBA 7(a) loan. Those with less than 20% ownership are usually not required to.
SBA policy generally requires an unconditional personal guaranty from all owners of 20% or more of the equity in the small business. This threshold ensures that individuals with a significant stake in the business are personally accountable. However, a lender may, at its discretion, require guaranties from non-owner spouses or individuals with less than 20% ownership if their personal assets are critical to the project or if they hold key management positions.
In a business with four partners owning 25% each, all four would sign personal guaranties. If one partner owned 15% and the others 85% combined, only the 85% combined owners would typically be required to guarantee.
Insider move
Lenders verify ownership percentages and ensure all required guarantors are identified and sign. They also assess the financial strength of all guarantors to ensure the guaranty provides meaningful recourse in case of default.
