Print The biggest home sale in La Jolla’s history — and the third-highest ever in San Diego County — took place a few weeks ago when a beachfront mansion sold for $24.7 million. Completed last year, the newly built 6,071-square-feet property at 8466 El Paseo Grande sold for one of the highest amounts in San Diego County in the last 12 months — a time period marked by a surging luxury market during the pandemic. While the sale was completed in late December, it was not announced by parties involved until this week. The biggest purchase in San Diego County history remains the 2007 sale of an oceanfront home in Del Mar for $48.2 million. The same house was later sold to Bill and Melinda Gates for $43 million last year.
