This sale establishes a new all-time benchmark for the town, surpassing the previous record of approximately $4.9 million and marking a significant milestone in the evolution of the Englewood Cliffs luxury housing market.

Since January 1, 2023, New Jersey Proper has represented 4 of the 10 highest residential sales in Englewood Cliffs, according to NJMLS data. This equates to 40% of the top 10 transactions in the borough over that time period, reflecting a consistent and measurable presence at the highest end of the market.

The property at 645 Summit Street reflects continued demand for newly constructed, architecturally driven homes in Bergen County, with design by Jordan Rosenberg and interiors by Vanessa DeLeon. The home’s scale, design execution, and positioning contributed to achieving a record-setting result.

Englewood Cliffs has increasingly emerged as one of Northern New Jersey’s most competitive luxury submarkets, driven by proximity to Manhattan, larger property footprints, and a growing pipeline of high-end new construction.

New Jersey Proper continues to maintain a leading share of the upper-tier market across Bergen County, with a particular concentration in transactions above $3 million.
