Manhattan Real Estate & Pied-à-Terre Advisory

The Global Key is a boutique advisory serving Manhattan buyers, pied-à-terre clients, and relocation seekers who demand discreet, strategic, and deeply personalized representation — across New York and beyond.

Real Estate & Lifestyle Concierge

The Global Key is a boutique real estate and lifestyle concierge specializing in Manhattan homes, pied-à-terres, and relocations for out-of-state and international clients.
We represent buyers and sellers of Manhattan co-ops, condos, and townhomes, while advising multi-city clients on second-home strategy and building requirements.
For clients who are not physically present or prefer a more private, discreet experience, we act as your trusted eyes on the ground providing property previews, video walkthroughs, and in-person representation in New York, across the U.S., and in select international markets. Beyond the transaction, we coordinate every detail of your move including relocation planning, vendor introductions, and ongoing pied-à-terre support.

Our Core Specialty

Pied-à-Terre & Multi-City Living

Our core niche is pied-à-terre and multi-city clients. We understand the unique needs of those who split their time between New York and other global hubs.

From strategy on whether a pied-à-terre makes sense, to matching you with buildings designed for part-time living, to aligning property decisions with your work and travel schedule—we’re built for this lifestyle.
