Reached by a 600-foot tree-lined drive, the eight-bedroom house at 11 Bay Road had last changed hands for $5,400,000 in 2015. It led five reported New York metro area home sales for the week ending September 20, 2026, which together totaled $49.28 million.
Quogue and Westhampton Dunes carried the week’s waterfront sales, while the three remaining closings were at New York City addresses, a pair in Flatiron and one in Chelsea.
