East Sister Rock Island has been on and off the market since 2011, when it was originally listed for $12 million. The 1.37-acre island with over 5,000 square feet of living area returned to the market in mid-December for $8.5 million, according to Zillow, marking a 29-percent reduction in price.
The four-bedroom, three-bathroom home is sustained by wind and solar energy, sits on a coral reef, and has a veranda stretching nearly 3,000 square feet. You can arrive by boat or chopper (there’s a helipad in the back). Vacationing here is also an option, with the island running for $1,000 per night most of the year.
