The median is the better guide to what a typical borrower here actually gets. Only 8.7 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.

Coverage
What this page does not hold.
Every item below could be filled with a plausible figure. None of them is. On a page a lender may read, a number that cannot be traced is worse than an absence, so the absences are named.
- Flood zone record counts are not held. The flood coverage export has not landed, so no count is shown rather than an estimated one.
- Traffic counts resolve in the platform, not in this dataset, so no AADT figure is printed here.
- Zoning is in build. Parcel level zoning is not published on this page.
