Your minimum contribution on an SBA 504 project, from SOP 50 10 8.1.
The 504 contribution is a percentage of "the Project cost, excluding administrative costs" (13 CFR 120.910). Enter that figure, not the loan amount.
On a 504 project a New Business is one "in operation for 2 years or less at the time the loan is approved". A change of ownership can also be treated as a New Business, and the SOP has a carve-out for some expansions under identical ownership. Ask your CDC.
