A 24-space mobile home park in Key Largo, FL. County records put it on 5.1 acres, built in 1974.
FEMA's flood map puts this park in zone X, outside the mapped special flood hazard area — one less financing or insurance hurdle than a park in a hazard zone faces. This mobile home park carries 24 spaces on the registry, without a vacancy count to say how full it runs. Everyday errands stay reasonably close: the essentials we mapped run 1–12 miles out. Internet is a strength around here: about 100% of homes in town can get 100/20 Mbps service, much of it fiber.

Distances are straight-line, so the drive is longer. Internet and neighborhood figures describe the surrounding town — and the rent benchmark, wildfire rank, and tornado count the wider county — not this park’s own lots. The fair market rent is apartment-style rent (HUD’s area benchmark), not this park’s lot rent. Rent limits are not legal advice.

For residents
- Water billing: if your park submeters water, Florida bills it at the cost of service with the combined service charge capped at 9% (§367.022(9)) — there's no markup on the water itself. Check the math free with the water submeter calculator, or read the Florida water-billing guide.
- Paying rent: ask the park office how they take payment. Parks that run on Lot Sidekick hand residents clear, itemized rent and water bills.
- Thinking about moving here? What to ask a park before you rent a lot, and what lot rent covers and how it goes up.

How much is lot rent at Captain Jax RV Resort?
Captain Jax RV Resort doesn't publish its lot rent anywhere we could find, and we won't guess at a figure. Call the park office to ask. For scale: HUD's FY 2026 fair market rent for a 2-bedroom rental around Monroe County is $2,504/mo — that's apartment-style rent for the area, and lot rent (the ground under a home you own) usually runs well below it. If you run this park, you can add your real lot rent to this page for free.
How much can lot rent go up at Captain Jax RV Resort?
Florida has no statewide cap on lot rent, but Chapter 723 requires 90 days' written notice (Statute §723.037), and an increase justified by comparable parks must be disclosed — residents can request mediation.

Park value estimate
Monroe County assesses this park at $11M — about $445,000 per space. The median across 12 other assessed parks in the county is $384,000 per space, so this one sits in the middle of the county range.
These are county assessments for tax purposes, not a market appraisal and not an asking price. A park's real value turns on its rent roll, its expenses and its utilities — none of which are in a public record.
