Chances are, if you love the energy and vitality of the city and you want to sell New York real estate, you’ve probably noticed it’s full of people with sharp elbows, too. So, how do you become a success in real estate brokers Bronx in the Big Apple? It’s not easy, but with a lot of hard work and adopting best practices of top agents, it can be done. Below we put together five traits of successful NYC real estate agents and brokers.

1. Work hard

This is a no-brainer. In a 2008 profile of Paula Del Nunzio — possibly the first press profile of the reticent super broker known for her mansion sales — writer Adam Piore cites her “maniacal work ethic.” Her competitor Dolly Lenz, who is one of the city’s top brokers, admires Del Nunzio’s tenaciousness, too. “To me, she’s a great role model. People make fun of her; people are jealous. They say she sleeps in the office. You walk in in the morning, and they say she hasn’t left. But I see it as a positive,” Lenz told The Real Deal.

This is a general sales principle, of course. Gary Keller, the founder of Keller Williams Realty, which by agent count is the largest brokerage in the U.S., has written, “more than anything else, expertise tracks with hours invested.” But in New York, the city that never sleeps, it has a special resonance. Put in the hours and you’ll be able to communicate with clients who are themselves working demanding schedules.

2. Shout from the rooftops

Look at the top NYC brokers as a group, and it seems like the quality that they all have in common is self-aggrandizement — they’re a bunch of people who appear to be tweeting, Instagram-ing, and filming TV shows as much as they’re selling real estate. For some, it’s their core personalities — these are people who love the spotlight. But for others, brand marketing — whether it’s through advertising or social media — is simply an essential part of the business.

A profile of “billion-dollar broker” Jacky Teplitzky in Real Estate Weekly mentions the advice of Barbara Corcoran, founder of the Corcoran Group and no stranger to TV herself: “You can be the smartest kid on the block, but if nobody knows your name, you’re not going to succeed.”

But, what if you are an introverted personality type? You can go far by publicizing your successes to your contact list — just make sure they have opted in to receive your emails or newsletters. Also, if you work for a large firm, make sure that your manager knows what you’re doing as they can often be a source of mentoring, not to mention sales leads.
