Billionaires are putting in place multi-million dollar homes on mega-ranches. Gross sales agent Robb Nelson says it be a real estate “Bonanza.” Ragged Light York Metropolis Mayor Michael Bloomberg paid $46 million for a 4,600-acre ranch in Colorado. A 41,000-acre ranch in South Dakota is going for $37 million. It comprises five bedrooms, a in point of fact geared up gym and a residence theater. The ranch is also a money maker with plant life, over 2,000 cattle and hundreds of untamed mustangs.
