Billionaire Bill Koch Lists Osterville Manse for $15 Million

Just after purchasing a Cape Cod mansion in January 2013 from philanthropist, Bunny Mellon, billionaire sailor and art collector, Bill Koch, has reportedly listed another luxury pad for $15 million in the neighborhood, according to several media reports.

According to the Business Journal, the home last sold for $1.6 million in 1983. Listing records claim that he home is an 8653 square feet single family residence sitting on a 68824 square feet lot. Built in 1929, the home comprises of nine bedrooms and 12 bathrooms.

The listing describes the home as:

On the south coast of Cape Cod, on the renowned private island of Oyster Harbors, only a few rare properties offer views of Nantucket Sound, a private sandy beach, and a deep water dock. Yachtsman and collector William Koch transformed a historic nine bedroom, twelve bath beach house built in 1929 into a cherished family compound. Distinguished by summer porches, seaside balconies, chef's kitchen and widow's walk this outstanding property reflects a keen sense of refinement. While superbly designed for grand entertaining, with timeless living space, beach house, granite pool and guest quarters, the home also offers the comfort and seclusion desired for peaceful family living and intimate gathering.

Currently, Koch lives at his Palm Beach residence. He also owns estates in the Castle Creek Valley, Aspen. He also owns a bear ranch just outside Aspen, which he is revamping to include a train station, jailhouse, saloon and a firehouse. The 21,000 square foot property will be used to frame his Old West memorabilia paintings and some other art collections, reports the Real Estalker.

Koch has such a huge real estate empire, he could easily imprison a person in one of his ranches and no one would ever know. Apparently that is exactly what happened. In late 2012, a former employee of Oxbow Carbon, a company owned by Bill Koch, filed a lawsuit against the billionaire and his agents accusing them of kidnapping him and holding him hostage after interrogating him on Koch's Bear ranch in Aspen, Colorado.
