Born of Palm Beach, Built for the World
Mizner Estate Properties was founded in 2004 by a small circle of Palm Beach insiders who believed that ultra-luxury real estate demanded something the market had never truly offered: absolute discretion, genuine expertise, and a concierge-level commitment to every client.
Named in honor of Addison Mizner — the visionary architect whose Mediterranean Revival masterpieces define the Palm Beach aesthetic — our firm carries forward his legacy of craftsmanship, beauty, and uncompromising standards.
Two decades on, we remain deliberately boutique. We do not chase volume. We pursue excellence. Every estate we represent is personally vetted by our principals, and every client relationship is managed with the same white-glove attention we would extend to family.

Our Approach
The Concierge Standard
01
Absolute Discretion
Many of our most significant transactions never appear on public records. We maintain an exclusive network of off-market estates available only to qualified buyers introduced through our firm.
02
Curated Representation
We accept fewer than twelve new listings per year. This deliberate restraint ensures every estate receives our full attention — bespoke marketing, private previews, and global outreach to family offices and private wealth managers.
03
Global Reach, Local Mastery
Our principals maintain active relationships with private banks, family offices, and wealth advisors across North America, Europe, and the Gulf. When a Mizner estate comes to market, the right buyers already know.
04
White-Glove Service
From first inquiry through closing and beyond, every client is assigned a dedicated principal — not an assistant, not a junior agent. Your transaction is personal to us because it is personal to you.
