The former Potomac estate of Dan and Tanya Snyder, once the personal residence of the former Washington Commanders owners, is officially heading to auction through Concierge Auctions, with proceeds benefiting the American Cancer Society.
Located at 11900 River Road, the sprawling 13-acre property was donated by the Snyders to the American Cancer Society in 2024. In July, prior to the auction announcement, the organization reduced the price to $24.9 million, a $5 million cut from its previous $29.9 million listing and nearly half of the $49 million it was originally listed for in early 2023.
Bidding opens December 5, 2025, at 3am EST and will close on December 18. The property remains listed for $24.9 million, with starting bids expected between $7.5 million and $11.5 million.
Additional details per the property description: Anchored along the Potomac River and surrounded by protected parkland, the French Chateau-inspired estate showcases more than 40,000 square feet of meticulously designed space across three structures. A collaboration between architect John Ike, designer Geoffrey Bradfield, and Horizon Builders, the limestone and slate residence is approached by a half-mile tree-lined drive that opens to panoramic river views.
The main residence spans roughly 25,000 square feet over four levels, featuring coffered ceilings, floor-to-ceiling windows, and imported stone detailing throughout. The lower level was built for entertainment, complete with a professional theater, clubroom with a full bar, and a restaurant-grade wine cellar.
Additional structures include a three-level guesthouse with 11 garage bays that can transform from an automotive showroom to a full event space, as well as a 4,500-square-foot staff residence for property management. Other amenities include a commercial chef’s kitchen, elevator access, heated pool, generator backup, automated snow-melt systems, and reverse osmosis water throughout.
Concierge Auctions describes the listing as “an extraordinary legacy opportunity,” noting that the full sale proceeds will benefit the American Cancer Society. The organization’s decision to auction the property comes after more than a year on the market, with the reduced price and auction format expected to draw global interest in one of the Washington region’s most luxurious estates.
Originally constructed in the early 2000s, the Snyder estate has long been one of Montgomery County’s most recognizable riverfront properties. Its upcoming auction marks a rare combination of ultra-luxury real estate and philanthropy, offering prospective buyers the chance to acquire a landmark property while supporting a major charitable cause.
