An oceanfront mansion on 5.9 acres in Southampton, N.Y. reportedly has just gone to contract after being listed for $65,000,000. gin-bitmap-i.bmpgin-bitmap-iv.bmpgin-bitmap-iii.bmpgin-bitmap-v.bmpgin-bitmap-vi.bmpgin-bitmap-vii.bmpgin-bitmap-ii.bmp The New York Post’s Braden Keil broke the story last Thursday about the apparent deal for the mansion, which is at 104 Gin Lane in Southampton. Keil noted correctly that the sale of the property, which once was the residence of Oscar-winning “Chicago” producer Marty Richards, could be the highest-priced “single-parcel” property sale ever in the Hamptons, if its sale price exceeds $58 million. Investor Ron Baron in May 2007 famously paid $103 million for a spread at 260 Further Lane in East Hampton, but it was in two transactions for two parcels, for $58 million and $45 million, through his 260 A LLC and 260 BC LLC companies. Features on the estate include a 13,200-square-foot mansion with six bedroom suites, a music room leading to the den, a cypress wood-paneled library, a breakfast room and additional staff quarters, according to listing information. The estate’s 7,500-square-foot guesthouse has a den and three en-suite bedrooms with ocean views, according to listing information. Also on the estate are an allee of sycamore trees over a winding driveway, a four-car garage and staff quarters, a large seaside pool with a spa, a tennis court, a stocked lily pond, award-winning rose gardens and a whopping 408 feet of ocean frontage with a 15-foot-deep rock revetment, according to listing information. Richards sold the estate in late 2003 for $23,000,000 to something called 1776 Investments Corp., according to public records. Keil wrote that the present owner – i.e., the entity behind 1776 Investments Corp. – is a “European businessman.” Keil added that he would divulge soon” the present owner’s name. We, however, can break the news that New York state records show that the “European businessman” behind 1776 Investments Corp. is an executive at Andlinger & Co. Andlinger is a private investment firm that turns around and sells troubled companies and that also sets up financing for leveraged buyouts.
