Two New York firms add up to make one new company.

CENTURY 21 NY Metro, formed from the acquisition of CENTURY 21 Kevin B. Brown and Dwelling Quest to create a powerhouse New York residential firm, announced its official launch this week.

The new company, owned and operated by RealStar Realty LLC, will have two offices which are located in Manhattan and Harlem, with more than 150 sales and rental associates. CENTURY 21 NY Metro will provide services that cover the complete range of residential categories including condos, co-ops, lofts, townhouses, and rentals.

The company will also carry the CENTURY 21 Fine Homes & Estates designation, an honor given to a select group of CENTURY 21offices worldwide that service the luxury homes segment.

"We are thrilled to see the CENTURY 21 name expand even further into the Manhattan market, which is a market that embodies the diversity, energy and drive that has come to be associated with CENTURY 21 System members," said Tom Kunz, president & CEO, Century 21 Real Estate LLC.

"With the full support and backing of Century 21 Real Estate LLC, the largest and most recognized residential real estate sales organization brand in the world, we are confident in our ability to offer the unparalleled service New Yorkers demand--service that is synonymous with the CENTURY 21 name," says Michael Simon, president and chief executive officer, CENTURY 21 NY Metro.

"Whether you are a native New Yorker, relocating from another part of the country, or an international customer, CENTURY 21 NY Metro has the resources to make the home buying, selling or renting process as smooth and as stress-free as possible."
