Keller Williams NYC: What Sets KW Agents Apart

Technology, training, and market reach that helps KW clients win in New York's competitive market

April 2026 • 7 min read • 25+ Years Experience

In April 2026, T3 Sixty ranked Keller Williams the No. 1 real estate franchise in the U.S. by agent count, transaction sides and sales volume, the ninth consecutive year. KW's own release counts 136,511 U.S.-based agents and 796,658 transaction sides for 2025. I joined Keller Williams NYC in 2016, after 15 years as principal broker at Montilla's 159 Real Estate in Upper Manhattan, and KW's global reach was the deciding factor.

What the KW Platform Provides, and What the Agent Provides

From Keller Williams

  • Training through KW University and KW MAPS Coaching
  • A global brand, the reason I chose KW in 2016
  • A franchise founded in 1983 and ranked No. 1 by T3 Sixty every year since it began tracking in 2018

From your agent

  • Mine: 1,100+ NYC transactions tracked at miltoncoste.com/listings
  • Mine: 15 years as principal broker reviewing every deal in the office before it went out
  • Building-level knowledge of co-ops, condos and boards

Scale and Reach

KW describes itself as the world's largest real estate franchise by agent count. T3 Sixty's ranking rests only on U.S.-based, KW-affiliated agents, so the figures above exclude KW's international network. A franchise ranking says nothing about any single agent, which is why the second column of the grid matters as much as the first.

Training and Standards

KW describes its training as KW University and KW MAPS Coaching, built on the books The Millionaire Real Estate Agent and SHIFT.

Technology and Marketing

I shoot my own 3D virtual tours and listing videos, started when the pandemic restricted in-person showings in 2020, and I publish walkthroughs and market updates on YouTube, Instagram, Facebook, LinkedIn, TikTok, X, Threads and Pinterest. miltoncoste.com is built and maintained hands-on. See how syndication reaches tens of thousands of agents.

Local Knowledge Still Decides the Deal

A platform does not know a building's financials, board or recent sales. My deepest building-level knowledge is in Washington Heights, Inwood and Hamilton Heights, and I cover all five boroughs and the Hudson Valley. Some of the deals I have closed are at miltoncoste.com/listings.

Questions to Put to Any Agent, KW or Not

  • • How many transactions in your building type and borough, and where can I see them?
  • • Who reviews the contract and board package details before they go out?
  • • What marketing do you produce yourself, and what do you hire out?
