Some friends of mine have a deposit down for one of the "cheaper" units, around 2000 sq-ft for $3m-4m I think. I sat in with them during a spiel at the Four Seasons hospitality setup at Dell Match Play. Pretty swanky. The boat marina where residents can just rent out a boat for the day seemed pretty cool, with little cabins above each boat slip. Just have to pay for the fuel. (OK, not really. They are still paying for all of it with the steep HOA fee lol)
Largest villas starting at $50m I believe.
Won't be delivered until 2025 IIRC.
