Born and raised as a first generation native New Yorker, Sabin was always interested in the ever changing NYC landscape. While his father drove a taxi cab up and down the streets of Manhattan
getting to know his passengers, Sabin learned very quickly the importance of forming and maintaining strong relationships.
At merely 22 years old, Sabin has built up a clientele of individuals
from the Forbes Billionaires list, CEOs, hedge fund and finance wolves, real estate moguls, art collectors, world renowned doctors, past and present politicians, and international bigshots. Sabin credits his success to his charismatic and outgoing personality and his ability to get along with just
about anyone. He stays true to his roots and never forgets where he came from, allowing him to build friendships with people in all circles of life and work on deals as small as a $2,000 studio rental
in Inwood or as big as a $40M penthouse on the Upper West Side.
Apart from real estate, Sabin is also an undergrad senior at Columbia University studying financial economics and concentrating in business management. Following graduation, Sabin will be continuing his studies at Columbia working towards his M.S. in Real Estate Development. His past and present academic career has allowed him to develop an innate ability to conduct deep research and analysis in order to properly understand the market and provide the best results for his clients.
Real Estate is a transaction of emotions and Sabin ensures that all of his clients are as comfortable as they can be in making one of the biggest decisions of their lives. He is a helping hand and a
friend.
I am using Mark to sell my Upper West Side co-op and to help me purchase another co-op on the Lower East Side. I first met Mark about 3 weeks ago when looking online at co-ops on the Lower East Side. On a frigid Sunday afternoon we went to view 10 apartments. Mark answers all of my questions almost immediately, and I have many. We just started showing my apartment and by the end of the second week he'll have been here 5 times - 3 times showing it to individuals and 2 open houses. He is very easy to work with. I would highly recommend him.— Marty S.
My best friend Rachel had used Mark to help find her new home. After visiting Rachel’s new home, I was so impressed and excited for them that I decided to buy in NYC and of course I called Mark. Rachel had also renovated the home, and many of the contractors she used were recommended by Mark. I knew I wanted to take on a project, so going to Mark was a no brainer after seeing his work with Rachel. We are in the process of renovating now, and all is going well thus far!— Jacqueline
Mark was a huge help in selling our house. Not only was he extremely communicative, he was also very friendly and made me and my wife very confident our house would be sold. Mark has a lot of building experience and was very helpful as well directing us to contractors and suppliers for a renovation project that turned out great. Mark always had solid input and a very deep network of real estate professionals. Thanks Mark!— Yuri
I had been looking for the right home for 6 months to no avail. A coworker of mine who had worked with Mark in the past recommended him to help find our home. After only a month Mark helped find our dream home! He then connected me with contractors to build a wall to create an additional bedroom and patch the wood floor. The contractor was great and Mark really facilitated the renovation. Wonderful experience!— Bridget B.
Mark was very easygoing and helpful. He explained all of the intricacies of the home buying process and was there by our side the entire time. He helped us understand coop vs condo and closing cost involved for each. We had so many questions and he had answers and a network of people to help, he introduced us to a great real estate lawyer. He was very patient and understanding. Overall, it was a very smooth experience, and I could not recommend him enough!— Joseph M.
After finding Mark on Zillow, the process of finding our dream home became seamless and worry-free. Mark scheduled all of the homes that we wanted to see and offered his own input and ideas on other listings. We finally found our dream house with the help of Mark, and we love living here now. Thanks Mark!— Sandra and Morgan
Mark and his team are very competent. They made the buying experience quite easy despite the fact that I never met him in person. Very easygoing. He's lived in NY nearly all of his life and it shows. Recommend him for your real estate needs.— Sharad D.
I was having trouble selling my home, but then I found Mark. Within only a month, I had received 2 offers. I noticed other Brokers had difficulty showing potential buyers a clear vision for how to renovate a convert our foyer into more usable space. Mark was fantastic helping buyers understand cost, time frames and design, as Mark has experience building homes. Mark was the best Real Estate move I had made!— Leslie M.
Mark is extremely knowledgeable when it comes to what is available on the market and went above and beyond what was expected. He searched for the best apartments that met my criteria and made sure each step of the process was as easy as possible. I highly recommend him.— Jaeson B.
Mark goes over and above. Large or small deals he is a true professional, with lots of heart. He was most helpful in guiding us through a process unusual to one not from the area. I would utilize Mark again without thinking twice.— Rachel C.
Mark was very accommodating and helpful when we sold our home. He made improvements to our online listing and used different tools like SEO to garner more online traffic. Our property was on the market for 103 days before Mark, but after his improvements to the listing, it sold only 18 days later. We could not thank Mark enough!— Alex and James
Mark is a very responsible agent and very easy to work with. He helps us a lot for our moving in process. He helped to coordinate for the walk through, contacted contractor for making closet and shades. He is very knowledgeable and responsible. I highly recommend him to our friends.— Cindy J.
After being recommended to Mark by a friend, I couldn’t be more thrilled of how the process unfolded. Mark was always available to address any questions I might have, and Mark was consistently communicative. I was very impressed by how smooth the process went.— Sophia D.
I have been working with mark for 1.5 years now. He is very patient and helpful. Mark connected me with 2 mortgage bankers and helped guide me through the bank commitment process. His recommendations have been fantastic, and they also speak very highly of Mark.— Max R.
