$13 million sale of Boulder estate shatters county record for home sale


This month’s $13 million sale of a Boulder estate qualifies as the county’s most expensive sale in history.

Over the past decade, Boulder’s top 10 sales for single-family residences all exceeded $6.5 million, with the second-most expensive hitting $10 million, according to Alana Watkins of VOCA Public Relations, referencing public records. The six-bedroom, six-bathroom home at 1489 Sunset Blvd. closed on Jan. 17.

“It’s not surprising to me that this home is setting records for home sales in Boulder County — it’s truly one of a kind,” said broker Marybeth Emerson of real estate agency Slifer Smith & Frampton.

The Sunset Boulevard home already set a previous record: the first to sell for $7 million in 2020, with Emerson serving as the buyer agent then. It is about 7,300 square feet, and sits on a little over 1 acre — close to Boulder’s Pearl Street. It was listed at $13 million.
