Our Story

Two Decades of Market Intelligence

RXB Realty Group was founded on a single conviction: that clients in New York's real estate market deserve advisors who think like investors, not just brokers. From our first transaction in Manhattan, we built a practice grounded in data, discretion, and long-term relationships.

Over two decades, we have advised landlords, sellers, and investors across every cycle the New York market has produced — from the post-2008 recovery to the pandemic-era dislocation and the subsequent resurgence of demand in prime submarkets.

Today, RXB operates as a trusted partner to a select roster of clients who value expertise over volume. We take on fewer engagements so we can deliver more on each one.

How We Work

Our Principles

Discretion

Every engagement is handled with strict confidentiality. We do not discuss client transactions, holdings, or strategies — ever.

Precision

We price, position, and negotiate with data. Gut instinct is no substitute for rigorous market analysis and financial modeling.

Access

Our network spans owners, developers, institutional counterparties, and legal and financial advisors — giving clients access that the open market cannot provide.

Alignment

We succeed when our clients succeed. Our advisory model is built around long-term relationships, not one-time transactions.

Where We Work

Deep Roots in New York's Core Markets

RXB Realty Group focuses exclusively on New York City, with particular depth in Manhattan's most active submarkets. Our market concentration is intentional — we believe deep local knowledge produces better outcomes than broad geographic coverage.
