The average approval of $572,031 sits well above the median of $150,000, pulled up by a few larger deals, so the median is the better guide to what a typical borrower here gets. Only 11.8 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.
