John M Cotter

  • John helped me buy a home

      John listened to me, which lead him to find the answers I needed,. He used his wealth of knowledge and great connections to help me secure a home. If you are buying or selling, he is the right person to be there for you at this important time in.your life.

    • Promptly scheduled viewings at my earliest convenience and provided many options as to available time slots. Very cool portal service that suggested several homes based on my own preferences. Kept me very informed on what was going on during the process of buying a home and answered all questions in a timely manner. Successfully negotiated multiple improvements/fixes on the house during pending sale. Was honest about homes that he believed had issues and were over priced, his goal was not to sell the most expensive house but rather find a good fit for me. 5/5 would recommend.

    • John was very professional and easy to work with for the sale of my house. He made sure it was a smooth process. He asked questions, he was detail oriented, was able to get things done in a timely manner, and most importantly - acted like a true pro!

    • I am a client of John Cotter, and I was very impressed with the service and insight that he provided me. John was always available for consultation, and he consistently addressed my questions and concerns promptly and professionally. I truly appreciated the fact that John was more concerned about finding the "right" condo for me that fit all my criteria......not the most expensive one. I would highly recommend John for any and all real estate needs.

    • John was always there when we needed him. He always answers and returns call or text at any time of day or night. He is dedicated to this business. He lives for real estate. He is a gentleman, prompt, and patient. He was never pushy or in a rush with us and he made us feel very at ease during the difficult buying process.

    • John worked very hard to make sure I was happy and we could close on my house quickly. Was great at communicating at any time of the day and recommended a great lender to work with.

    • We met John at an open house. At the time we weren't super serious about listing our house and buying another one. John ended up showing us a few hours a week or so later, one of which we wrote an offer on. Needless to say, things moved quickly--we listed our house and had multiple offers within 48 hours. Oh, did I mention the COVID-19 pandemic became an issue about half-way through this process? Adding that complexity is sure to stress any home seller/buyer, but John kept the wheels on the train! John was very friendly, extremely responsive to texts/phone calls/emails, and has done what he said he would do when he said he would do it. If nothing else, that's more than you get with most brokers! We would not hesitate to use John again!

    • John was great helping us find homes. It took some time for a to pick but we were happy to have friendly person like john to help us along our way of being first time home owners.

    • Professional, knowledgeable, helpful are just a couple of adjectives I would use to describe John. As a first time home buyer, John worked with me to schedule viewings, worked alongside the lender, worked out any scheduling conflicts & made the process as painless as possible. I highly recommend him!

    • John is an outstanding agent to work with. I recently worked with John in selling my Royal Oak house and he was extremely knowledgeable about the local market. He walked through the comps, makes a recommendation, and listens to his clients questions, comments, and concerns. He has very prompt with communication and always follow through. Thanks John!

    • This was a difficult time to Sell my Condo and buy my little Dream Home but John was a Great support and helped me through to the end. There were times when the Banks were so backed up because of CoVid19 and it was hard to get answers and a Closing Date lined up for the 4 of us but John never faultered and reassured me that it was all going to work out and that this was the right house and right move and he was absolutely right. I am so happy he was there to guide me/us. I can't Thank him enough and wish him great success.

    • I can not recommend John enough as a real estate agent. As a first time home buyer, I was very nervous and stressed about the entire process. This stress was alleviated by John's expertise of the process and thorough presentation of applicable housing data at every step along the way. There was never any point where I felt like I was making a decision without the proper education beforehand. Further, if you are ever worried about not being able to get a hold of your agent at critical times, this is the guy for you. He always texted back immediately and followed up on any action items with extreme efficiency. The reason I was able to get my home (which was by far the best house we saw during the entire process) was because we were able to see it the first night and got an offer in immediately after. It is hard to imagine that he finds time to sleep or eat, but none the less, I was thoroughly impressed. Overall, I just felt like John was in my corner during this entire process. He truly wanted to help me find the best home and did not rush me into any decisions that I would regret. I obviously don't have a lot to compare to as a first time buyer, but I really can't think of what more he could have done for me. If you are looking for someone who you can trust through the entire process and execute when you need them to, John is your guy.

    • It was a joy to work with Lucy and her teammate, John, in our home buying process. They were prompt in answering all questions and provided excellent service. Home buying is extremely stressful but Lucy was patient and understanding. We will definitely recommend her to family and friends.

    • If you are buying a home, you will never go wrong with John Cotter. As a first time home buyer, the process of buying a home seemed overwhelmingly exhausting. But l was lucky that the it was very successful and painless; plus it took less than average time to close, thanks to John Cotter, who defines professionalism and is truly pleasant to work with. John Cotter is immensely knowledgeable about the local market and was extremely patient when it comes to explaining things to me who has little knowledge about real estate. Even when it's off hour, John was very responsive and always answer my confusion. I was never left in the dark. On top of that, every single detail during the process has been taken care of and the entire process was smooth like butter. I'm very happy that I closed my first home. Thanks for your tremendous help, John!
