Christian was helpful and diligent throughout the entire apartment search. He listened to all I had to say regarding apartments, quickly reaching out for me and responding to my texts and calls. He had a clear sense of what I was looking for. I appreciate his help immensely !

Christian is the best. He is extremely knowledgeable and respectful, and he genuinely cares about your wants and needs when it comes to finding a new home. I always knew he was going to show me places well worth my time, and he makes the moving and hunting process fun rather than stressful! He was beyond helpful from beginning to end and was always available to answer any questions i had at any time of day. He is a dream to work with and I will continue to shout his name from the rooftops (or in my case, my new beautiful fire escape).

In my view, John Harrison is the most honest, hard working real estate agent in NYC. He is a consummate professional and always goes above the call of duty. John helped us in buying our condo in NYC and later assisted in renting it. He was always there to help us navigate the complex NYC real estate rules and provided appropriate guidance throughout the process. I would highly recommend John as real estate agent to anyone who is looking to buy, sell or rent a place in NY.

So, where do I start. I live in Massachusetts and I inherited some property in Brooklyn, NY. I struggled to attempt to sell it on my own unsuccessfully. Then while my wife was having breakfast with my daughter at a hotel she ran into John and his family, and started discussing our situation. John offered to give us advice with no strings attached, and no pressure to be my agent. Of course I was suspect, but eventually through our discussions I could see John was just trying to help me. I came to trust John and started to work with him on the sale. After taking his advice and taking his direction he took us from a sale that was SIGNIFICANTLY below what I was asking to double what I was looking for. He handled the process of getting the property in a shape that drove interest through the roof. Took care of the showing of the property and negotiated the bidding war on my families behalf. He ensured that we received the strongest offer and brought a difficult situation to a wonderful conclusion. I couldnt have asked for a more professional individual to guide me through this entire process. The one thing that impressed me the most and for anyone reading this review, is I have yet to meet John face to face. I have never met John. We conducted this entire process while I was in Massachusetts and he was in New York. John was so honest that I left this entire sale in his hands and I will tell you it was the best thing I ever did. Thanks to him I am currently building a new house and have the finances to pay the entire house off and provide for my family thanks to John. And this all happened because John saw a family in need of some direction and some help that he didnt know. He didnt have to help us at all but that tells you about his character as a person. I will forever be in his debt, and if you are considering working with John, trust me, you want John and his team in your corner. Hands down, he will not steer you wrong and take his advice because it will be the best move you will ever make. Thank you, John, from my entire family.

John is a very smart and knowledgable broker who understand the New York market very well. He has guided us through the complexities of a 1031 exchange, explaining things in a very clear way and helping us to find the right people, from mortgage brokers to insurance agents. He was also very helpful to find new tenants and even taking on the role of a superintendent to make their rental start as smooth as possible.
