Frequently asked questions

Who has to personally guarantee an SBA loan?

Generally every owner of 20% or more of the business must give an unconditional personal guarantee on SBA 7(a) and 504 loans. Lenders may also require guarantees from key managers or other parties on a case-by-case basis.

Is the SBA personal guarantee negotiable?

The guarantee itself is largely required by SBA rules, but the specifics — the collateral pledged, any life-insurance assignment, and whether a spouse must sign — can sometimes be discussed with your lender within the SBA’s SOP limits.

What collateral does an SBA loan require?

The SBA expects loans to be secured to the extent you have collateral available. That can include business assets and, for larger loans, a lien on personal real estate such as home equity. Exact requirements depend on loan size and lender policy.
