Harrison Grandelli Team @ CORE

Fifth Avenue remains one of Manhattan’s most active corridors for residential sales, where discretion and onsite service can make the difference between a listing that lingers and one that moves quickly. Harrison Grandelli Team @ CORE operates from the eleventh floor of 149 5th Ave, offering buyers and sellers a private setting for every stage of the transaction—from initial walk-throughs to final paperwork—without ever leaving the address.

Appointments are required, a detail that underscores the firm’s approach to real estate in a neighborhood where space is both coveted and contested. The team’s presence on the eleventh floor places them steps from Flatiron’s retail core, yet far enough above street level to offer a quiet vantage point over the district’s constant flux. While the area’s mix of pre-war co-ops and modern condos continues to draw interest, having an agent who can navigate both building histories and board requirements becomes essential.

Those ready to schedule a viewing or discuss market timing can reach the office at (212) 601-2638. For directions to the building, the map is here. The elevator bank closes promptly at six, so plan accordingly.
