Police Raid $4.4 Million San Francisco Mansion Amid Elaborate Deed Fraud Investigation
San Francisco authorities arrested Diana Peng following a raid on a $4.4 million Sea Cliff estate. According to Realtor.com, the 42-year-old and accomplice Brandon Aadee allegedly utilized forged deeds to seize the property. The investigation highlights a complex scheme involving multiple title transfers intended to facilitate the illegal sale of the luxury Tudor-style residence.

Context from Industry Pulse
The Sea Cliff incident underscores the vulnerabilities of high-value real estate left vacant by international owners. According to Realtor.com, the property at the center of the dispute was purchased for $2.41 million in 2013 but sat empty for five years, allowing it to become a target for sophisticated deed fraud. With the median listing price in the neighborhood hovering around $4.5 million, the potential profit for fraudulent sellers is substantial. This case also highlights the role of municipal intervention, as the San Francisco Board of Supervisors had to authorize a tax payoff to clear the title for a future public auction, illustrating the administrative hurdles in reclaiming distressed luxury assets.
Law enforcement officials conducted a four-hour operation at a luxury residence located at 250 32nd Ave. in the prestigious Sea Cliff neighborhood. Realtor.com reports that police arrested Diana Peng on multiple charges, including fraud, narcotics possession, and being a felon in possession of a firearm. During the raid, officers also rescued seven dogs from the premises and towed a vehicle belonging to the suspect. The incident follows months of community complaints regarding unauthorized occupants at the property.
The legal dispute centers on allegations from San Francisco City Attorney David Chiu that Peng and her associate Brandon Aadee used forged notary signatures and fraudulent documents to claim ownership of the 3,000-square-foot home. As Realtor.com notes, the pair allegedly transferred the property title between themselves eight times to create a false paper trail. The legitimate owners had moved abroad in 2019, leaving the house vacant and eventually accumulating over $340,000 in unpaid property taxes.
Neighbors in the high-end enclave, which is home to various celebrities and tech founders, had reported suspicious activity at the site for over a year. Realtor.com indicates that complaints filed with the city described unauthorized plumbing work and the site being operated as an unpermitted group home. The property had fallen into significant disrepair during the years it was left abandoned by the original owners before the alleged squatters moved in using burglary tools.
The San Francisco Board of Supervisors recently approved a resolution to settle the outstanding tax debt, which is expected to allow the city to put the mansion up for auction later this year. Both suspects involved in the civil and criminal proceedings have extensive histories of financial crimes, including prior convictions for identity theft, perjury, and defrauding federal agencies. Peng is currently being held without bail as the city attorney continues to pursue a civil case to prevent the defendants from profiting from the alleged theft.
The Industry Pulse Bottom Line
This $4.4 million mansion raid demonstrates how prolonged property abandonment invites sophisticated title fraud. For the luxury market, it emphasizes that even elite zip codes require active management to prevent legal and physical takeovers by organized squatters.
