What Our Clients Are Saying

“I am not easy to work with, I never know the questions to ask and I take a long time deliberating. Michele, with Mark Seiden Real Estate, was truly patient, kind, and connected to so many parts of the community that is was a much better experience than I could have hoped for. As someone who wants choices, Michele was able to provide me with many excellent people who covered. different parts of the home buying process- a process I had no idea how to manage and I am so grateful for the knowledge Michele was able to share with me. ”

“Allyson did a wonderful job of assisting us in appraising the sale value of our condo. She was particularly helpful in advising us on how we should "stage" our place; what was necessary to do to prepare our place for the market, what was optional, and what not to do. The whole Seiden team was amazing! They scheduled every-other-week open houses, were completely prepared for COVID precautions, and getting potential buyers in to look. The team also helped us the entire process; preparing our unit, showing the property, discussion offers, and finally the sale. They prepared written reports for us following each showing and open house as well as a summary report. The team really worked hard to get potential buyers in to view the property! The market had slowed by the time we were selling, and the Seiden team really worked to consistently bring in potential buyers and maintain contact with us. I would definitely recommend them! I think the Mark Seiden Team is the preeminent real estate group in Ossining, and Briarcliff Manor area. They have represented me in purchases, sale, and rental. Always ethical and professional in their representation. They support after the sale too. I needed referrals for many trades and Mark Seiden always came through. I recommend them without hesitation for Westchester real estate needs. We have a short list of people we enjoy working with and an even shorter list for people that we absolutely trust. Allison Imondo lands on both of those lists. A trusted advisor that perfectly understands people and the market, and leverages her experience of both to put her clients in the best position to make the most informed and best decision for themselves and their loved ones. We give Ali our highest level of recommendation - she earns it every time. ”

“From the very beginning of our home buying journey, the Mark Seiden Real Estate Team gave us all the support we needed to make our dream of owning a home a reality. As first time homebuyers and new to the home buying process; we always felt we were in good hands, especially with Allison Imondo as our agent, guiding us along the way, and always being there to answer whatever questions we had (which were many). Not once did we ever feel on our own, and despite the difficult and complicated process of financing our purchase through the use of grants; Mark Seiden Real Estate Team gave us the stability we needed to ensure we always felt in control of our journey. ”

“ I can't speak highly enough of my experience with Mark Seiden's Real Estate's agent ; "George Gabor". Due to my family situation, I had to move fast from another state & start my new Job, you can imagine how nervous a person can get, George Gabor made my life super easy. George Gabor was wonderful in keeping the transaction moving along and getting to closing in a timely manner. He was always available to answer my questions (and the Salers!). He was so responsive and is the sweetes person. I had an outstanding experience! I now consider George as a family friend and would highly recommend him to anyone that is searching for a new home. Thanks again to Mark Seiden Real Estate Team for being such a pleasure to work with. Thank you George Gabor! ”

“I have lived in Ossining for years, and after my son graduated from college I wanted to sell my home and start the next phase of my life. After a bit of research, I discovered Mark Seiden's Real Estate Team and met Allyson Davidov. The very first time that I met her I knew she was going to help me change my life. She assured me that not only could she sell my home, but that I could make a decent profit as well. I never knew that selling a home could go so smoothly, especially during a pandemic!!! From beginning to end, Allyson and the Mark Seiden Team went above and beyond to make the process of selling my home a safe experience. Her professionalism, expertise, and knowledge of the community and real estate market are the reasons that I have achieved my goal. ”

“Mark has been a fellow community member and friend for nearly three decades. I knew I could trust him and the Mark Seiden Real Estate team to put together a plan to sell rental property I owned and wanted to unload. I worked with Mark and Allyson to find the perfect price point that would allow my house to not only sell quickly, but to sell to people that would give it a loving home and become wonderful neighbors. The whole process also began when the Covid pandemic shutdown started. They took all the safety precautions necessary and made sure that rules were followed for everyone's health and well-being. From there on, it was smooth and almost effortless. ”

About The Mark Seiden Real Estate Team

And that clearly is the result of our efforts for our clients.

All of our clients are, or were, going through major life transitions each and every day during every transaction.
