Martin County is the 33rd largest of 67 Florida counties by population. A median home costs 5.2 times median household income, which is severely unaffordable by national standards. 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 story product rather than schools.

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

These are counts of establishments physically operating in the county, not listings, so they are the supply side a feasibility study measures demand against. County Business Patterns counts private establishments with paid employees in March 2023, while the Quarterly Census of Employment and Wages above counts every unemployment-insured employer, public ones included, as a 2024 annual average, so the two establishment and employment counts differ.

The average approval of $705,474 sits well above the median of $274,000, pulled up by a few larger deals, so the median is the better guide to what a typical borrower here 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.

SBA loan default and charge-off rates in Martin County
Do SBA loans in Martin County get paid back?

- Paid in full50
- Charged off4
- Charge-off rate on resolved loans7.4 percent
- Status: Paid in full50
- Status: Exempt from disclosure201
- Status: Cancelled29
- Status: Charged off4
- Status: Committed, not yet disbursed19
Of the 54 loans that have reached a final outcome, 7.4 percent were charged off. This is computed only over resolved loans, because a loan still running has not yet succeeded or failed and counting it either way would be wrong.
Compare against the national and state SBA charge-off rates, computed the same way over resolved loans only.
