HARLEM, NY · COMPASS
Harlem is a Block-by-Block Market.
We Know Every One of Them.
Harlem isn't one neighborhood — it's ten intricate micro-markets where the rules change at every corner. Park frontage that adds a million on Mount Morris Park barely moves the needle on Manhattanville. Landmarks overlays, co-op board math, and historic-district rules quietly decide what your renovation actually costs. You need a team that knows the blocks intimately — and the muscle of a national brand behind every deal. Together, the Harlem Properties Team has nearly 50 years showing and selling Upper Manhattan, backed by Compass, the country's largest residential brokerage. We've been quoted on Harlem in The New York Times, The Wall Street Journal, Bloomberg, The New York Post, and NBC New York.

LEADERSHIP
John McGuinness, founder and president.
John built Harlem Properties Team around townhouse expertise, neighborhood memory, and direct negotiation. He still works the same Upper Manhattan blocks he studies, giving clients a founder-led point of view on pricing, renovation risk, and where value is quietly shifting.
