A median home costs 5.2 times median household income, which is a stretched ownership market and usually shows up as rental demand. Residents 65 and over outnumber those under 18, at 32.2 percent against 16.1 percent, which points demand at health care, services and single storey product rather than schools.

The county has grown 4.57 percent since the 2020 census base. Deaths exceeded births in 2024, so all of the growth came from people moving in. A market held up by migration alone is more sensitive to a change in relative cost than one growing from household formation.

The average approval of $705,474 sits well above the median of $274,000, 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 15.2 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.
