Editor's note: "What's the Big Deal?" runs Sundays and is based on the most expensive property transaction recorded in Pitkin County each week.

Worth noting: This marked Pitkin's County's most expensive single-family sale of the year and second overall to the February sale of the Hotel Jerome and former Aspen Times building for $72.5 million.

Known as the Summit House and marketed by Aspen Snowmass Sotheby's International Realty, the furnished property originally was listed for $65 million in October 2014. The asking price was high enough to capture loads of media attention, including a video tour by Fox 31 in Denver.

The property also includes a 4,150-square-foot guest home and a vacant lot.

"As one of the most magnificent homes ever built in Colorado, the irreplaceable size, premier location, expansive views and numerous amenities are unrivaled in Aspen," gushed marketing materials for the property, further declaring that "the size of this home cannot be duplicated under current land-use codes, making this legacy home a rare commodity, indeed." New homes in Pitkin County are capped at 5,750 square feet.

Public records link the seller to Fort Worth, Texas, resident Duer Wagner III, whose namesake oil and gas company filed for bankruptcy earlier this year, according to published reports.
