WASHINGTON — The most expensive residential sale in Washington last month closed for 4.5 percent more than its most recent list price, and its buyers got a seven-bedroom compound on a half-acre lot near Northwest D.C.’s Palisades neighborhood.

The home, at 3035 Chain Bridge Road, was built in 1940 and includes nine bathrooms, 7,250-square-feet of interior space, a pool, steam room and sauna, and private gardens.

The Washington region’s most expensive residential sales in October were all in the District, Bethesda, Potomac, Chevy Chase, Great Falls and McLean. Scroll through the gallery to see all of them.
