Mandalay Ranch-Aspen

Owned by Hollywood producer Peter Guber, this 650-acre ranch includes wildflower meadows, ponds, a 15,000-square-foot main home and guest and caretaker cabins totaling 8,000 square feet. According to listing agent Bob Ritchie, initially Guber planned to sell only the land, but because there was so much interest in the house, he decided to throw that in too. Assuming the buyer puts a $12 million down payment on the property and obtains a 30-year loan with 5.97% interest, the monthly payments would be roughly $301,000.
