The average approval of $762,431 sits well above the median of $500,000, 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. 35.4 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.

31 Census places lie wholly or partly in LaSalle County. 30 carry enough published place level data for a page of their own and are linked. The rest are named here and not linked, because the American Community Survey and the SBA record between them do not carry enough about them to write an honest page. A place existing is itself worth knowing, so nothing in the county is left out.
