The average approval of $598,652 sits well above the median of $225,000, 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 16.7 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.

- Charge off rate on resolved loans14.1 percent
- Status: Paid in full79

Compare against the national and state SBA charge-off rates, computed the same way over resolved loans only.

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.

42 Census places lie wholly or partly in McHenry County. 37 carry enough published place level data for a page of their own and are linked.

A further 11 SBA approvals in McHenry County are recorded against borrower cities that match no Census place, the largest being Village Of Lakewood, Algonguin, Sturtevant. Those are postal cities and unincorporated areas rather than incorporated places, so no page claims them, and their lending is counted in this county's totals above rather than under any city.
