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.

Park value estimate
The county roll carries no assessed value for this park, so here's a comparison instead. Across 7 assessed parks in St. Johns County the median works out to $53,000 per space. At 33 spaces that puts a comparable assessment somewhere around $1.8M — call it $688,000 to $2.8M, which is the middle half of the county's 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.
