Four Los Angeles County Properties Rank Among the Country’s Top 10 Year-To-Date Mega-Sales.

Green Gables, a storied 74-acre compound in the Bay Area town of Woodside, ranked as the most expensive U.S. home sale in September at $85 million, according to a new report released by Redfin.

The September sales list reflects continued strength in West Coast trophy properties: four of the month’s top deals were in California, and three others closed in Colorado ski markets. In addition to the Woodside estate, a $58.3 million sale in Aspen and a two-parcel, $55 million Montecito transaction rounded out the month’s top three.
