Alejandro Santo Domingo's House

The Colombian American billionaire purchased this oceanfront property in 2012 for $28.5M. When his father, Julio Mario Santo Domingo Pumarejo, died in October 2011, he became the face of his father's Santo Domingo Group (more than 100 companies, beer empire).

As of May 2014, Forbes estimates his net worth at $13.4 billion, making him the second-richest Colombian and the 102nd richest person in the world.

The former owner of this Hamptons home is private equity billionaire Marc Rowan.
