From Curbed:
Once the most expensive home for sale in California at $65 million, Locksley Hall in Belvedere sold today for $47.5 million, just $1.5 million shy of its latest asking price of $49 million. The sale breaks the record for the highest reported single-family home sale in San Francisco proper by $12 million, and the highest reported sale in Belvedere by around $22 million.
