Summary
The property south of San Francisco not only becomes the most expensive sale in its affluent town of Hillsborough, doubling a previous record, but is also the most expensive sale in northern California this year, according to listing agent Jennifer Gilson of Golden Gate Sotheby’s International Realty. Gilson declined to share any details about the buyer, other than that the new owner of 3000 Ralston Avenue is a man in the AI industry. The property, known as “ Villa de Verano ”, was initially listed at $88m, and sat on the market for only four months and 22 days.
