The median is the better guide to what a typical borrower here actually gets. 34.8 percent of approvals run on real estate terms of 240 months or more, so this is a market where SBA credit is buying buildings, not just funding operations.

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.
