Florida Keys — Private Island Near Sydney Sweeney's Mansion Listed

A private island located minutes from Sydney Sweeney's Florida Keys mansion has come onto the market, marketed as an off-grid property with its own sandy beach, according to a report from Mansion Global. The headline ties the parcel's location directly to the actress's existing Keys property as a selling point.

What is actually for sale, according to the report?

Mansion Global's report describes a private island offering off-grid living and a sandy beach, positioned as being close to Sweeney's Florida Keys mansion. That is the full scope of confirmed detail available from the originating headline and summary reviewed for this piece. The report does not specify the island's name, its exact Keys location, or which chain of islands it sits within.

How close is the island to Sweeney's mansion?

The word used in the report is "minutes," not a mile count or boat-time figure. No distance in miles, nautical miles, or minutes-by-boat appears in the material reviewed. Readers searching for a precise proximity figure will not find one in the current reporting; the comparison functions as a marketing reference point rather than a measured distance.

What does "off-grid" mean for a listing like this?

The term signals that the property is not connected to municipal power, water, or sewer lines — a common framing for small Keys islands that rely on generators, solar arrays, cisterns, or septic systems instead. HTT News has covered other off-grid builds, including a couple's self-built dome home, covered here, though that project is unrelated to this listing and involved different systems and a different state. The Mansion Global report itself does not break out which specific off-grid systems — solar, generator, rainwater catchment — are installed on this island.

What hasn't the report disclosed?

Three figures a buyer would normally expect are absent from the material reviewed: asking price, total acreage or square footage, and the listing brokerage. None of those numbers appear in the headline or summary available for this story, so none are reported here. That gap matters for a property type where price per acre on private Keys islands varies widely depending on buildable land, dock rights, and flood zoning — none of which the current report addresses.

Where can readers find more on off-grid living?

For readers interested in the broader off-grid lifestyle rather than this specific listing, HTT News has published a practical guide to joining a community tool library, a lower-cost entry point into self-sufficient living than purchasing an island. Mansion Global's full listing details, when published with price and acreage, would be the next figures to confirm before this story can be reported with the numbers a buyer or shopper would need.
