A 10,000-square-foot East Islip home with about 360 feet of shoreline is on the market for $4.5 million.
The house, built in 2000, occupies more than 5.5 acres along the Champlin Creek.
"This could be a family compound," says Eric Ramsay of Ramsay Realtors, the listing agent.
The six-bedroom, seven-bathroom, two-half-bathroom house comes with a 3,400-square-foot guesthouse plus two separate lots of open land.
The main home has views of the Great South Bay from the kitchen, family room and all the bedrooms.
"The house is really positioned to maximize the views," Ramsay says. "It has beautiful water views, and also views of the nature preserve [Seatuck National Wildlife Refuge]. You don't see any other homes -- it's complete privacy."
There's a lighted tennis court with a small tennis house, an in-ground pool, in-ground sprinklers and a deep water dock.
Taxes for the entire property are $95,000 a year.
