"
Jonathan was a tremendous aid in helping me navigate the first-time homebuyer process. He was very transparent with me throughout the whole process and had many resources that I could depend on. He allowed me to form my own opinions about property and supplemented my observations with his own afterwards while simultaneously not being pushy at all.
I also found his wealth of experience in construction invaluable because it provided me extra insight to what makes a good home which was perfect in my situation since I did a gut rehab. He even recommended a great contractor/designer friend of his. Would wholeheartedly recommend Jonathan to any buyer or seller in NYC!

Jonathan was absolutely phenomenal. I could not imagine finding a better agent. As a first-time buyer, I didn’t know all of the questions I should be asking ,and he would proactively provide this information, which made me feel like I was walking through this process with someone who had my best interest. I absolutely would recommend Jonathan to anyone. He is kind, quick, knowledgeable, reliable, and wonderful at his job. Five stars!

When our daughter decided to purchase an apartment in Manhattan, she engaged Jonathan to represent her as her realtor. We live in California and soon learned that purchasing property in New York is a COMPLETELY different animal, and without a competent, professional realtor, we would have found ourselves stranded! Jonathan was far more than that! He lined up several places within our budget for us to visit in a short period of time as we were only there for a couple of days. He did an excellent job narrowing down the vast number of listings to show us ones that met her criteria and budget, and not wasting our time. But to me what sets him apart is the level of care he has provided since we met him. He negotiated a great deal for us, and even went back when we realized the HOA would be increasing to get additional concessions! He responds to every inquiry quickly and helped us make sense of the myriad requirements a COOP endures. Not once did we ever feel like we were bothering him and we honestly could not have completed all the necessary requirements without his assistance & patience. To say it has been overwhelming is an understatement, and there is NO way we would have completed everything on time without Jonathan helping us and guiding us every step of the way. He is a true professional, and hopefully we will work together again.

"Working with Jonathan in finding my dream home was an incredible experience. From the very beginning, his confidence, expertise and dedication made the entire home-buying process for me smooth, enjoyable, and stressless.
He was not only prompt in all his responses but he took the time to understand my preferences, budget, and specific needs, ensuring that every property he presented aligned with my perfect home vision.
Not only does he have an in-depth knowledge of the Brooklyn real estate market with various neighborhoods but his background in development & construction gave invaluable insight especially in new development condos, which is what I ended up purchasing in.
He was patient, never pushy, and always willing to explore new options until we found the perfect match. His negotiation skills were top-notch resulting in a deal that completely exceeded my expectations.
I would wholeheartedly and unhesitantly recommend Jonathan to any buyer & seller in the Brooklyn market sector."

"Our daughter was accepted to PA school, and we had one month to find a place for her to live in Brooklyn on a budget! You can imagine our stress. We tried looking ourselves, and after a week, we realized we desperately needed help. We weren’t sure what neighborhood would be best, what would be fair pricing, and how to avoid bidding wars. We were fortunate to click on a property and were introduced to Jonathan. Jonathan jumped into action, and we were looking at apartments in our budget within the week. He is resourceful, has a great insight into the market, and absolutely wonderful to work with. We made an offer on a fabulous apartment on our first day and closed in 2 months. Jonathan made this happen for us. He went above and beyond to navigate us through the process, provided invaluable advice, great contacts, and answered all our texts, emails, and calls timely and always with a great attitude. We were able to move our daughter into her fabulous apartment in the nick of time. We owe that to Jonathan.

"Working with Jonathan was an absolute pleasure. When we began our search for our first home in Brooklyn, we were overwhelmed and discouraged with bidding wars and limited inventory. From our first meeting with Jonathan, we saw a path forward. His experience and insight made navigating the market easy and his kind and compassionate attitude made the process enjoyable. Not only did he secure us an amazing deal in a difficult market, but he supported us along every step of the way. His advice was invaluable and he was always available to answer any questions or concerns. I would happily recommend Jonathan to friends and family in search of a new home.

"Working with Jonathan was an absolute pleasure. We were looking for an apartment in Brooklyn and his knowledge of the area was truly remarkable. Jonathan was incredibly responsive throughout the whole process and responded to calls and texts immediately. He listened to our needs and found properties that were appropriate for us. He never tried to “sell” us anything but rather sought to satisfied our needs. His service did not end after we signed the contract and he continued to assist us through closing. Jonathan’s knowledge of construction was an added bonus.
Overall, Jonathan added tremendous value to our apartment search and we can wholeheartedly recommend him without reservation!

"Working with Jon was great! Unlike other brokers he wasn’t too pushy or abrasive. He took the time to understand my needs and budget and worked to find the right unit at a price for a price and terms that were mutually beneficial. His knowledge & experience within the new development sector also aided tremendously in the purchase of my new construction condo. Would highly recommend him to both buyers & sellers!

" I purchased my first investment property from Jonathan in his New Development Condo in Bed-Stuy. Jonathan is the best and I would totally do another deal with him any day of the week for my next investment which is hopefully coming up in the near future.
He is very honest, professional, and made the whole process so smooth & easy for me. Before I decided to purchase his actual listing, he did show me multiple other properties around that area which was very helpful to see the comparables but ultimately his building was the right price in the best location.
I have purchased many primary residency properties during my lifetime and Jonathan was the perfect agent and we never hit any bumps in the road like I did with other agents in the past.
I would highly recommend him & his firm Compass to all my friends and families that are looking for any properties in Brooklyn or Queens.

"Jonathan was an extremely helpful broker. He didn’t just try to sell me an apartment but he genuinely cared about my satisfaction.
He was very responsive and considerate of my time and even after the lease was signed, he went out of his way to help me with any questions that I had.
I wouldn’t hesitate to recommend him to my family and friends.

"“We had a few agents before Jonathan and immediately the difference was clear. He had a level of knowledge, expertise, and helpfulness that stood out.
He answered every question along the way and anticipated issues we never would have thought of. He advocated for us and saved us tons of money in negotiations & incentives. We knew through the entire process that we were in good hands, which is significant in a process as stressful as buying your first place in NYC.”
