This $17 million Brooklyn mansion with a mobster history now comes with a bonus - another house

At one time, this "bonkers" estate was the most expensive home in Brooklyn, on sale for $30 million in 2013.

But the next year, it was given a price chop - down to $17 million.

After briefly disappearing from the market, it's up for grabs once more, still priced at $17 million. This time, a whole extra home has been thrown in to sweeten the deal.

The ten-bedroom Mill Basin property is a gated waterfront compound with a storied past and more than 23,000 square feet of interior space. The main house was originally built and owned by John Rosatti, a multi-millionaire with mob connections to the Colombo crime family. He then sold the property to Russian heiress Galina Anisimova (known as the mother of the "Russian Paris Hilton") for $3 million in the late '90s.

Outside, the mansion has a 1,000-square-foot pool, a 40-person pavilion for parties, and 30,000 square feet of outdoor gardens. And then there's the 7,800-square-foot guest house - priced as an independent property at $8 million, according to Curbed NY - which is now yours for free if you purchase the mansion. It's a full three-story home of limestone, glass, and cast iron, with a bamboo garden, three full bedroom suites, a roof deck with Manhattan skyline views, and an elevator.

The main house boasts a downstairs wine cellar, 257 feet of waterfront, a four-car garage, and a two-boat marina. Taken together, this is quite a compound, admittedly more akin in style to something you'd see in Miami than in Brooklyn.

James Cornell and Leslie Marshall of Corcoran Real Estate Group are currently sharing the listing.
