Client Testimonials

I couldn't have asked for a better experience with the buying of my new home and the selling of my old one. MJ is top-notch!

Stan K.

Mary Jean Agostini and her team are the gold standards of real estate transactions. She walked in the door prepared and ready to accomplish the task. Her entire team has great communication skills and is very knowledgeable. We can't say enough. This is the team to choose if you want an agent/team that will get the job done.

Nancy and Bob T.

MJ is highly recommended by several people and knows Berlin well.

Sally B.

MJ has an excellent reputation and is knows the local market particularly with multi-family homes. I could not have asked for a more competent, professional, and courteous experience.

Stan K.

MJ and her team were great to work with. They were always accommodating, polite, friendly. MJ is quite knowledgeable and has deep relationships with other real estate members. Pricing houses can always be a challenge since homeowners want to get the best pricing for their home. We listened to MJ's advice and as a result accepted an offer, 5 days after the house was listed. The closing took longer than expected, but as a result of the COVID pandemic and its effect on the banking community- limited workers, working from home,etc. Regardless, we were very happy with MJ and her team and would definitely recommend their services.

Marie D.

I moved out of state and needed someone who could handle the sale of my house without me being present. MJ and her team were terrific all throughout the process. When work needed to be done to the home they arranged for everything and had it taken care of right away. The house sold in literally one hour! The pre-listing marketing was phenomenal and the team made sure that we closed in about a month. MJ and her team made this the smoothest, most pleasant sale I have ever experienced. I can't recommend them highly enough.

Betsy C.

I cannot say enough about MJ and her team. She/they are the BEST! MJ always answered my e-mails / texts / calls immediately and if she didn't have the answer she would get back to me very quickly with the information I needed. My house sold in ONE DAY! This was in the middle of the COVID outbreak to make this even more impressive. MJ constructed a plan for every step of the process from the "coming soon" yard sign, to the house viewing, and to the final closing that took into my concerns over the COVID situation and other personal concerns. Even the vendors she recommended to perform various jobs were outstanding. I would recommend MJ and her team to anyone who is looking to sell their home!

Jim M.

Mary Jean, Beck and Sarah are not only professional but they really care about you and your home. And they were great dealing with the realtors on the other side of the transaction, especially when those realtors were being difficult.

Lisa B.

Mary Jean Agnostini and staff were great to work with. They were professional, helpful and extremely knowledgeable. MJ provides service above what most realtors would have. I am so grateful that she was our realtor. I would highly recommend her and her agency.

Susan L.

The photographer very effectively showcased my home. The floor plan was a great idea, I think it helped any buyers get a true feel for the layout of the house.

Kim M.

MJ was honestly the best choice for us: she knew the town, the market - so extremely knowledgeable. Tons of experience. She was away on vacation when we listed our home, and her co-worker Becky took care of us beautifully in her absence. However, we heard from MJ constantly despite her being away, via text and phone, and walked us through everything. Both of them were hard working, connected to us and our sale - I mean plugged in. Every step of the way, they did what needed to be done. Every step of the way, MJ and her team kept us in the loop. If they said they were going to call or text, they did. They made sure we understood everything that was happening. Our home was on the market for 6 days before we got one written and two verbal offers. The day MJ got back from her vacation, she stepped off the plane and drove to our house with the written offer. She helped us navigate the negotiations and counseled us on what to do....mind you, this sale was happening during the pandemic! We closed on the house in a little over a month. Mission accomplished - in the best possible way. I cannot say enough good things about MJ and her team. We would HIGHLY recommend them to anyone thinking of buying or selling a house.

Holly K.

Mary Jean and her team made purchasing our home seamless and easy. They were always available and responded to our concerns and questions in an expeditious manner.

Stephen and Anne D.

I will always use Mary Jean Agostini and her team. They know what they are doing and I recommend them often to others. She really knows her craft! MJ and Becky were fantastic to work with, and I appreciate all they did. The sale from beginning to end was seamless! MJ and her team are the only Realty team I would ever use! I can’t thank them enough for all they did! My house was under deposit in the first 24 hours and sold within six weeks.

We also had a lot of contact with Rebecca from the office and enjoyed working with her very much. I was facilitating the sale of my 92-year-old father's home. He had been in the house for over 40 years so the thought of leaving was somewhat stressful on him. Both MJ and Rebecca were very patient in dealing with him and helping him feel as comfortable as possible throughout the whole process. We had worked with MJ's mom when we bought a Berlin property many years ago. We had a fantastic experience. We had hoped the "apple didn't fall far from the tree" and were not disappointed. My dad was very satisfied with everyone he dealt with and the whole sales process. We had multiple offers on the house within two days of putting it on the market. Since I was working with MJ from 1,000 miles away through most of the process, I relied on her and her team a great deal. She was also instrumental in providing local contacts to help with the donation of furniture and such and with trash haul away. That was a tremendous help, again because I was trying to manage everything from Georgia.

Bruce Gregory S.

Sarah was amazing to work with! She was very easy to get along with, timely, provided us with great advise as needed, and assisted us fully with every step of the buying process. She went out of her way to assist us in our needs and that meant a lot to us.
