A Sea Cliff home sale to biotech CEO Michael Henderson reportedly set a new San Francisco record for price per square foot at $4,574, shifting the luxury real estate narrative from AI to biotech wealth.

A $20 million off-market home sale in San Francisco's exclusive Sea Cliff neighborhood has established a new city record for price per square foot, with biotech CEO Michael Henderson reportedly securing the property at an eye-watering $4,574 per square foot. The transaction signals a notable shift in the ultra-luxury real estate market, moving beyond the familiar narrative of AI-fueled wealth and into the deep pockets of the Bay Area's biotech sector.

The sale of the 4,372-square-foot residence at 740 El Camino del Mar in late June set the new benchmark, surpassing the previous single-family home record of approximately $3,800 per square foot, according to Compass Chief Economist Mike Simonsen, as reported by The SF Standard. Only a few high-end condominium sales have approached this figure previously. While an exact deed transfer confirming the buyer and sale price is not readily available through online public records—San Francisco's Assessor-Recorder's Office shields ownership information from general online searches—the SF Standard's report identifies Henderson as the buyer, citing loan documents associated with the sale.

Henderson, the CEO of Apogee Therapeutics, recently saw his company acquired by pharmaceutical giant AbbVie in a $10.9 billion deal. This significant liquidity event appears to have fueled the high-value personal real estate acquisition. The sellers were noted as gastroenterologists Daniel Conlin and Robert Elsen, who had purchased the 1938-built home overlooking China Beach for $5.4 million in 2010 from the Shorenstein family.

Listing agent Neal Ward of Compass, who touted the record on social media, noted to the SF Standard that the sale reflects a "broader shift at the top of the market" driven by "exceptional demand across San Francisco’s Northside." The luxury market in San Francisco continues to experience extremely tight inventory, particularly for coveted cliffside residences like the one in Sea Cliff. This scarcity, combined with the property's unobstructed bay views, drives buyers to pay a premium, even for homes likely to undergo millions in renovations.

While the reported record highlights continued robust demand at the top end of the market, the specific details of the property transfer and the full scope of Henderson's personal investment remain opaque without access to specific recorded deeds or a more detailed breakdown of the acquisition funds. What remains clear is the enduring allure of prime San Francisco real estate for the newly liquid in the Bay Area's innovation economy.
