Interesting question! So I looked. NPR quotes:

Financier Stephen Deckoff paid $60 million for Great St. James and Little St. James through his SD Investments firm, a spokesperson told NPR.

The purchase price reflects a steep discount from the $110 million for which the two properties were recently listed.

Little St. James spans around 71.6 acres and includes "a helipad, private dock, gas station, high-capacity water filtration, 2 pools, the main compound, 4 guest villas, 3 private beaches, gym, tiki hut," and other buildings, according to its real estate listing.

Still can't believe it's that cheap in a world with 3,028 billionaires. That's pocket lint for these people! Which should be fucking enraging.
