Winters in Colorado are cold, but real estate in the Centennial State is anything but.
One of the billionaire Koch brothers is trying again to sell his lavish Aspen compound — this time for its highest-ever price: $125 million.
If the estate were to sell for anywhere close to its asking price, it would be the most expensive home ever sold in Colorado.
Two other billionaires, former casino mogul Steve Wynn and financier Thomas Peterffy, set the current record in April 2024, paying $108 million for a 22,405-square-foot Aspen home. It marked the first time a sale in the state reached nine digits, placing Aspen among other rarified communities where properties trade for that much, including New York, LA, Palm Beach, and Miami.
William “Bill” Koch sold his stake in the family conglomerate, Koch Industries, to his brothersfor $470 million in 1983. Fast forward to 2007, when Koch spent a relatively small sum — $26.5 million — on a former dude ranch just outside the posh ski town of Aspen.
Today, after extensive renovations, it has a 16,600-square-foot main lodge and seven cabins, one of which is a home gym. The total square footage of all the structures is about 25,300. The 53-acre property also offers ample Aspen-suitable amenities, including hot tubs, hiking trails, and an altitude-acclimation room.
Koch — who is worth $2 billion as of February 21, according to Forbes — told The Wall Street Journal that the $125 million asking price is fitting given that a few of the area’s ultraluxury homes have sold for around $6,000 per square foot.
“If we applied that to our 25,000 square feet, our asking price would be $150 million,” Koch told the Journal.
“Scarcity fuels luxury sales in Aspen’s real estate market. Just as high-end brands like Hermès and Rolex create demand through limited availability, Aspen’s appeal outpaces its real estate demand,” Koch’s listing agent Steven Shane, of Compass, said in an email.
