California compounds and Colorado ski houses made up the lion’s share of September’s most expensive home sales

The Green Gables estate in the Bay Area, which consists of seven houses on 74 acres, was the most expensive home sale of September, bringing in $85 million. That’s according to a new report from Redfin, the real estate brokerage powered by Rocket.

It’s followed by an Aspen, CO property that sold for $58.3 million. Next comes a multi-property sale in Montecito, CA, consisting of an estate previously owned by Ellen DeGeneres and Portia de Rossi and a 3-acre lot, which brought in $55 million total.

All in all, four of September’s most expensive sales were in California, and three were in Colorado ski towns. Two were in New York—one in the Hamptons and one in Manhattan—and one was in Palm Beach, FL. The top three sold for more than $50 million, and all 10 sold for more than $30 million.
