Bill Brisben's house

William O. Brisben is a Cincinnati real estate developer. He founded and built Brisben Cos into a national developer and operator of apartment communities. At one time, his company owned 20,000 units in 20 states. He sold the company in 2002 and was appointed by President George W. Bush a US ambassador to UNICEF until 2009, for whom he was a "Ranger" fundraiser. In 2010, he and his son, Brent Brisben, bought salvage rights to 75 square miles of Atlantic Ocean off the coast of Florida. They believe up to US$900 million worth of gold, silver, jewels and artefacts from an 18th century fleet of Spanish ships is buried deep below the ocean floor there. In just a month of diving, they've already found $500,000 worth of loot including a 400-year-old cannon, 51 gold and 41 silver coins dated from 1698.

This home is listed for $11.5 million.
