The Mark O'Brien Team

I can’t say enough great things about Mark. He’s not only an expert in his field but also an incredibly personable and highly professional realtor. Throughout the process of purchasing a home in Brooklyn, Mark provided genuine, insightful guidance every step of the way, making the experience both smooth and enjoyable. If you're looking to buy a home in NYC, I wholeheartedly recommend Mark for his expertise, dedication, and exceptional support.

As a first time buyer moving to NYC - Mark, his team and broad professional network made the process a very positive experience. We felt very fortunate to have found Mark - he listened to us, helped us navigate the NYC real estate market and provided valued guidance from start to finish! We are thrilled to be in our Chelsea apartment!

LOVED working with Mark and his team. Mark is very knowledgeable about real estate from condos to coops and everything in between. We enjoyed viewing apartments with him as he always pointed out something we wouldn't have considered about the building, unit, etc. He was extremely helpful during the initial offer to contract negotiation and very hands-on during the coop application / board interview process. I'd work with Mark again and recommend him to friends and family.

Mark was wonderful helping us navigate finding our Brooklyn home. We spent months going through different options together and ultimately decided on a place we are very happy to call home. Really appreciated his measured diligence and patience throughout the process. Would recommend him and his team to anyone looking to navigate the NYC real estate market.

Mark and his team were great to work with. Responsive, professional and supportive. Buying a place in NYC is quite a process, and I felt like they were on my team each step of the way. It was nice to have that relationship as a busy tech professional with limited time, like many New Yorkers. Besides supporting people with home purchases, he renovates historic town houses around the city and is passionate about real estate.
