Justin Duffy

Justin Duffy

Licensed Real Estate Salesperson

Justin Duffy was born and raised in Brick, New Jersey, down by the famous---and now infamous---Jersey Shore. Born to a police officer and a veterinary technician, he had a very interesting and educational upbringing. This small town New Jersey origin has allowed him to truly appreciate human connection and community.

When Justin graduated high school, his parents separated and he made a move up to Elizabeth, NJ with his father. He spent four years in Elizabeth learning about himself and the beauty and diversity of people. During this time he began building a career in fashion retail as a visual merchandising manager, which eventually lead him to New York City.

After a year of living in Brooklyn and designing store and window displays for top retail chains in Manhattan, Justin decided to leave the fashion world in pursuit of something more fulfilling. He had always had an interest in real estate, not because of the income potential, but because of the people. It's all about relationships.

"There are no bad experiences; just good stories. The same goes for the people and the adventures you encounter while working in New York City real estate. It's all beautiful and I am so grateful to be able to meet and help so many amazing people on a daily basis."

Justin now works with the largest independently owned real estate firm in New York City, getting to know his clients better than they know themselves---and finding them the homes of their dreams. When he's not helping his clients, you can find Justin at a yoga studio in Brooklyn, an art gallery in Chelsea, or practicing with the local improv group.

Justin is a superstar! My wife & I moved to NYC late February and needed to find a place asap. Our requirements were not the easiest (short tenancy, location etc..) and we had spoken to a few agents before and were very nervous about the whole process. Then I came across Justin Duffy on one of the real estate websites and sent him and email. From get-go Justin was amazing! He was warm and friendly, very accommodating and extremely helpful. He had excellent knowledge of the city and very quickly pointed us to a few places we might like. Infact, the place we moved into (less than a week later!) was no.1 on the list Justin made for us. Justin went ABOVE AND BEYOND to make sure we were able to get the place. He did an amazing job speaking to the landlord and guarantors on our behalf and put an admirable effort until he was finally able to secure the apartment for us. Justin is down to earth, friendly, very knowledgable and a pleasure to work with. Justin, thank you for making my wife & I feel welcome here in NYC and making one of the most difficult aspects of our trip so much easier. We saved a lot of stress and sleepless nights thanks to you.

Justin helped me in finding my most recent apartment. As the process is always a bit stressful, Justin made it feel smooth from start to finish. He provided me with a lot of options and wanted to ensure my needs were all met. He was also persistent in finding alternative options when the first apartment I was interested in did not work out. He was super helpful along the way and it was truly a pleasure working with him!

Great working with Justin Duffy and Aubree Brown. Very knowledgeable, efficient and professional. Amazed that I was able to secure an apartment with all documentation done within a week from my start of the search.

Justin has been immensely professional, thorough, and talented. He made the entire process (which is tricky even under the best of circumstances) very straightforward and clear. Even when we hit a snag with the leasing company, Justin remained confident and determined to work with them to get the deal we wanted without losing much time - he followed up with the leasing company every day, and relayed every new piece of information to me immediately. Every minor question I had about the process, Justin responded attentively with a thorough and highly detailed answer. When we began, he quickly understood exactly what I was looking for, and showed me my ideal apartment almost immediately.

I'm so glad Justin handled my apartment hunting. He's patient, knowledgeable, accessible, and very proactive when it comes down to nailing down the apartment that I was interested in. He made the process as seamless as possible with minimum amount of effort required from my end. Would definitely recommend to anyone that is ready to move!

Justin was great! He made finding an apartment easy and painless. Renting an apartment in New York City can be challenging, but Justin made it simple.

I am a graduate student and he was able to work with my situation and find me an apartment that was perfect for my needs. Plus he is genuinely a cool guy and fun to hang out with while home hunting. I would definitely recommend Justin!

Justin was incredibly helpful in finding an apartment in Manhattan. Not only was he the only broker to return my appointment request within a reasonable amount of time, he ended up showing us a solid range of apartments and we landed a place within one day.

He was also extremely helpful as a liaison between the landlord and us, giving us honest feedback about what we should expect and how to navigate the application procedure.

I could not have asked for a more honest, professional, or knowledgeable real estate broker upon my move to New York. Neither me nor my mother were familiar at all with the NYC real estate market; luckily, we had Justin Duffy to take care of us and I found the perfect apartment, a place I would never have found on my own!
Justin was reliable, friendly, and easy to work with and I would definitely recommend him to anyone who needs a real estate agent in NYC.

I was referred to Justin Duffy as the local relocation agent for my company. He was efficient and responsive, found me what I was looking for quickly, and secured a lease on the terms I required. He was kind and professional. I will certainly recommend Justin.
