What it funds

SBA Express: program overview
What it is
A delivery method inside the 7(a) program. The lender uses its own forms and procedures and gets an accelerated SBA response, in exchange for a lower SBA guarantee percentage than Standard 7(a).
What it funds
The same uses as 7(a), including revolving lines of credit, which Standard 7(a) term loans do not offer.
Trade-off
Faster turnaround and lighter paperwork, against a smaller guaranteed portion, which some lenders price for.
Current SBA Express maximum loan size and guarantee percentage are set by SBA notice and change. Confirm them on sba.gov or with your lender; this site does not publish an unverified figure.
