The average approval of $522,120 sits well above the median of $180,000, so a small number of large deals is pulling the mean up. The median is the better guide to what a typical borrower here actually gets. Only 20.0 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.
