Excellent Agent
John Mangini guided us through a very difficult decision - to sell our home of 38 years. All phone calls to John were answered or returned promptly. John was always polite and reassuring, always answering our concerns. We lived out of state when our house was listed with John. John and his assistant, Laura Healy took great care that our unoccupied house was well cared for - staging done, etc.
Overall , John Mangini went the extra mile as a Real Estate Agent.

John put extra time and effort to make this deal happen on time where I had to do 1031 transfer to another property. Timely closing was really important to me and John made this happen as he was on top of all the issues on daily basis and kept me up-to-date on everything with this closing.

John Mangini came highly recommended to me as I was about to sell my mom's house, the house I grew up in, so there was a strong emotional side to this. John is the most caring person. He scheduled open houses, followed every lead, reported back to me on all leads, since no one was living in the house he would always let me know how many showings were scheduled for the day. John stayed on top of everything. We were going to be away and John even kept an eye on the house. I would not hesitate to recommend John to anyone buying or selling. You would be in good hands!

John made the whole process smooth as glass. He anticipated my needs every step of the way and made it easy to sell my property. All the advice he gave me for finishing touches and the care and attention to detail he paid to the photos and the listing were worth every penny.

John's extensive market knowledge, both of the selling and rental landscapes provided me with the insights needed to make informed decisions about my property. His practical approach was particularly valuable. He didn't just list my options; he delved into detailed analyses, presenting scenarios for selling outright, renting, and even a rent-to-sell strategy. His expertise shone through as he explained the potential returns and market dynamics associated with each option. In an industry where agents might prioritize their commission over client needs, John stood out by focusing on what was best for me and my property. He was upfront about the pros and cons of each decision, especially in screening potential renters. John has a keen eye for detail and a knack for problem-solving, qualities that were crucial in managing the complexities of tenant selection. John truly functioned as a trusted real estate "consultant," offering practical recommendations and genuine care for my best interests. I would highly recommend John to anyone looking to navigate the complexities of the real estate market with a reliable, expert, and honest partner at their side.

For this senior, single homeowner making a first home sale, John was the perfect choice.
Having regularly received John's data analysis mailings of the real estate market in Warren, I knew he had a deeply studied knowledge of home values. When my time to move arrived, I read his numerous client reviews as well. Now, post home closing, I can heartily verify the excellence expressed is definitely not overstated. Although visitors to my home regularly made positive comments, John's recommendations for bringing it to market readiness yielded most welcome results. Contracts came in quickly from the well-attended Open House. In 2025's turbulent market, John's extensive expertise and professional demeanor quickly gained my confidence. His willingness to help with the smallest details, thorough explanations of every step of the process, and quick response to my calls, confirmed throughout that I could not have made a better choice for a realtor.

John was critical to the successful sale. Interacting with town officials to be certain all inspections were cleared and certificate of occupancy was issued in a timely fashion. He also coordinated with the buyers broker to be sure they had what the needed cleaned up on final walk thru. He stayed with the project til the closing was official.

John was very knowledgeable, professional and helpful in every possible way in selling our Warren home. He really went above and beyond providing help with his valuable resources. He even spent time with many trips to storage for us. The whole family was very grateful for John's help in making this selling experience a successful one.

John was my realtor for sale of my house in warren. I couldn’t have asked for a better representative. Simply Selling a house is not what a great realtor does. It also requires promptness,, patience and experience in the applicable market. A good realtor like John can advise on repair contractors if needed, movers and other service assistance. And of course , it requires someone who is a good go between with the other realtor. John did it all. He was always available when I called. He would meet personally whenever needed. And if I had a question, he either knew the answer or researched it for me. If you are thinking of selling or buying. John and his team are really thr best choice by far . I am positive he won’t disappoint you!
