Listed by: Christie's International Real Estate Group-Franklin Lakes · James Reitz · 201-951-1158MLS#: 26015826Last updated: 05/28/2026Description
Tucked at the end of a quiet dead-end street in one of Mahwah’s established residential neighborhoods, 37 Nilsen Avenue is the kind of opportunity buyers wait for: a flat, level acre with the space, setting, and upside to create something truly special. The existing home needs work, but the canvas is exceptional - an oversized detached garage with room for up to four cars, a vintage pool cabana structure that hints at the property’s past and future potential with a private, usable property surrounded by mature trees. Renovate, expand, or explore new construction possibilities, all subject to approvals. With access to Mahwah’s public school system, including Joyce Kilmer, Ramapo Ridge, and Mahwah High, this is a compelling project for a buyer, builder, or visionary end user ready to bring new life to a rare piece of Mahwah.
