Under Oak, a French Norman Revival estate set on a 2.27-acre double lot in Washington’s American University Park, sold for $8.75 million, the highest-priced home sale publicly reported in the Washington, D.C. metro area for the week ending August 9, 2026. Together the week’s five leading closings accounted for $27.29 million in Washington-area real estate.
The sales span American University Park, Kalorama, Alexandria, Luxmanor and Boyce, recorded across the District of Columbia, Virginia and Maryland. Build years on record run from 1905 to 2026, and the group ranges from a newly completed Rockville house to a 224-acre farm along the Shenandoah River.
No. 1 — $8,750,000 · 4220 Nebraska Ave NW, Washington, D.C.
Under Oak, a stone-and-stucco estate reached by a long private drive in the American University Park area of Northwest Washington, sold for $8,750,000 on August 7, 2026. The residence carries 11 bedrooms and 10 bathrooms and stands on a 2.27-acre double lot that includes an adjoining parcel recorded as lot 1727//0005.
Listing materials identify Victor Mindeleff as the architect of the 1927 design, built of stone and stucco beneath a slate roof in the French Norman Revival manner. The house has been expanded over the years in keeping with the original architecture, and listing materials place it among Washington’s significant historic estates.
Park-like grounds surround the residence, planted with mature specimen trees and landscaped gardens and stepped with terraces. A swimming pool sits among them, and several accessory buildings stand on the property, including a gatehouse, a pool house and garages. The long drive sets the house well back from Nebraska Avenue NW.
Sassy Jacobs of Washington Fine Properties, LLC was the listing agent. The $8,750,000 transaction ranked No. 1 in RealtyWire’s Washington, D.C. Metro Area Top 5 home sales for the week ending August 9, 2026, the highest reported price in the metro that week.

No. 5 — $3,250,000 · 9533 Howellsville Rd, Boyce, Virginia
Idlewild River Farm, 224 acres along the Shenandoah River outside Boyce, Virginia, took the No. 5 position at $3,250,000 in a sale recorded August 3, 2026. The land carries 1.7 miles of river frontage and is protected by a Virginia Outdoor Foundation conservation easement.
About 120 acres front the river, where cleared paths lead to swimming holes and shaded picnic spots, and fenced pastures between the water and the house are set up for horses or livestock. Across Howellsville Road, another 100 wooded acres rise to a ridgeline at 800 feet of elevation, laced with trails for hunting, riding and hiking.
The residence was reconstructed in 2009 on the original site, a Federal-style brick house that keeps the exterior form of the historic Idlewild home built circa 1853. It offers four bedrooms, four and a half baths and a reported 4,000 square feet, with wide porches spanning the front and rear elevations and windows framing the pond, pastures and Blue Ridge Mountains. Bricks kiln-fired on the farm for the 1850s house were reused in the Carriage House, now a detached garage with a farm office, and the former estate kitchen has been converted into a one-bedroom guest house.
