We cannot say enough about Mary-Lou McDonough. She is an exceptional Realtor and made every step of selling our home easy, from our initial market analysis andpricing our property appropriately to staging our home to show its best features. She went above and beyond the call of duty, helping to organize and declutter shelves and closets as well as paying final bills before we moved out. Mary-Lou is extremely knowledgeable of the housing market and

what buyers are looking for and how to best showcase the features of a property. Most importantly, Mary-Lou was warm, encouraging and positive through the whole process and we loved working with her.We sold our place for so much more than we expected and were so happy with Mary-Lou's services. We would definitely use here again and highly recommend her to anyone who is selling or buying.

Cil Cangiano came well recommended and we understand why. She is dedicated to her task, works diligently in moving the house quickly and above target price, and is knowledgeable of the housing market in Boston as well as our house’s local market. Cil suggested improvements that in the end easily returned well more than the investment, set up the house for showing by bringing in furnishings that looked great in the house, conducted open houses that were timely, well advertised, and drew many buyers, produced a very professional and impressive large format glossy color brochure on the house complete with photos by a professional photographer, and helped guide the fast sale through the relatively complicated closing processes. She, her colleague Mary-Lou, and her team from Barrett Sotheby’s Realty really did an outstanding job overall. We too now agree and highly recommend that Cil Cangiano is the agent you want to sell your home.

After interviewing three of Lexington's top Realtors, I decided to work with Mary-Lou McDonough to sell my condo. I found her to be the most sincere with an unquestionable willingness to help me throughout the process. Since my husband was living aboard at the time, I appreciated all the assistance and support she provided. Mary-Lou and her team did an amazing job getting my house ready for the market. She coordinated cleaners, packers and with the assistance of her team did a spectacular job staging my home. She was able to generate multiple offers after the first weekend and my condo sold for well above the list price. Her attention to of all the details made an otherwise overwhelming process much more manageable and a lot less stressful. I am happy to recommend Mary-Lou to my family and friends.

It was a pleasure working with Mary-Lou while selling our home in Lexington, MA. Mary-Lou is exceptional in terms of what she does - right from strategizing the selling process, to providing hands-on help with staging, to taking timely care of all the critical details in the entire selling process. Mary-Lou was incredibly helpful in handling some last minute unforeseen issues by herself after we left our house in Lexington and helped us in a smooth transition. She is thoughtful, hard-working, and a deal maker. We highly recommend her as a real estate agent.


I was completely satisfied with Mary-Lou's help in purchasing my condo. She was always available with any help or assistance I needed, as well as quickly responding to and moving the negotiation process along expeditiously. I was always able to trust her responsiveness, which was always reassuring. In addition, she kept my best interests in mind. Mary-Lou is very knowledgeable, trustworthy, and hard working, which all make for great assets for a Realtor.

Selling a house is a formidable challenge. Deciding to sell a house in a week and selling it that weekend is unprecedented. We attribute our success to the experience and expertise of Mary-Lou McDonough and to her commitment and dedication to her clients. Mary-Lou was able to mobilize the resources we needed to prepare our home for an open house within one week of our decision and worked long hours to ensure that it had maximal appeal to potential buyers. Her hard work and diligence and meticulous attention to detail translated into several offers above asking the first open house weekend. Throughout the entire complex process, we felt confident that Mary-Lou would expertly guide us. She provided the reassurances that made the ordeal of selling one’s home less emotionally debilitating. Even after we secured a buyer, she continued her involvement and worked to ensure that all the contingencies were addressed so that the sale would come to fruition. Mary-Lou’s commitment to her clients is apparent and we attribute our success to her unique combination of experience, competency, determination, and understanding of relationships. We recommend her highly and feel she is the only person we would ever trust in any real estate transaction. Exceptional. Five stars.

Buying a home in a highly sought-after community with a competitive market like Lexington can be very stressful.

I would highly recommend Mary-Lou to anyone looking to buy a home in Lexington.
Buyer - 36 Paul Revere Road, Lexington

It is with my highest pleasure to recommend Mary-Lou McDonough. Mary-Lou helped my boyfriend buy his first home. At a very young age my boyfriend knew buying a home and making it his own was one of his greatest life goals. Since the age of 14 he saved every paycheck from his weekend job, and continued to save during his new career as a plumber as a young adult. Mary-Lou understood the magnitude of this goal for my boyfriend and was able to make his goal her own as well. Through the entire process, Mary-Lou made herself available 24/7 via text/call/email/face to face to answer any and all questions and ease any concerns in the utmost professional manner. As a first time home buyer, the road to closing may seem complicated and tedious, however, Mary-Lou made that journey as smooth and painless as possible. It made my heart swell with pride to see my boyfriend in his very own home with the keys in hand looking as accomplished as ever, and we both have Mary-Lou to thank for this incredible milestone.

"My wife and I have moved 14 times and Mary-Lou is by far(!) the best realtor we have ever encountered. She recently helped us both sell our home and buy our next one. As our selling or buying agent she was amazing. Her instincts on how to price and market our house was spot on. She generated significant interest in our sale and we quickly found and closed with a buyer with a great offer in terms of price and terms. On the buy side she listened carefully to our desires, worked hard to find homes that fit our wants, and she found the perfect place for us. Her advice on purchase terms was again spot on and we are now, thanks to Mary-Lou, living happily ever after in our new home. Thank you Mary-Lou!”
Tom & Beverly Gillett, Sellers/Buyers

I would highly recommend Mary-Lou McDonough to anyone seeking to purchase a home in Lexington or the surrounding areas.  Mary-Lou was really easy to work with, even when I wasn't!  She was flexible and met my needs, was easy to communicate via email, text and phone, she really adapted to my style of communication, which made me feel very at ease.  She was available for me early in the morning, late at night, weekends, she really worked around my busy schedule.  Mary-Lou kept me appraised of all of the fast changing inventory in a hot market, and eventually helped us find a great home, before it ever got listed.  I truly believe it was Mary-Lou's connections, knowledge of the market and diligence that got us into our ideal new home.  Once we found the home, Mary-Lou made the process of offer, purchase and sale and closing a breeze.  I really felt like I had someone looking after my best interests throughout the entire process.  The purchase of our new home went so well, that I also decided to work with Mary-Lou to sell my condo, it was the first time that I'd ever sold real estate, and Mary-Lou walked us through step-by-step of what we needed to be thinking about and doing, and when it came time to list, she got us a great price and fast, which was our highest priority.  I'd work with Mary-Lou McDonough on the purchase or sale of any property in the future and would recommend her highly to anyone seeking a true professional real estate agent.

"My husband and I had a mission: Find a two-family home in East Arlington, Massachusetts; Mary-Lou McDonough made it her mission, too. Mary-Lou was a professional from start to finish. She took the time to really understand our needs, our price range and our expectation. She is very knowledgeable of the real estate process. Her experience as both a seller’s agent and a buyer’s agent is invaluable to her clients, no matter which side of the transaction she is representing. This is because her knowledge of the process and strategies from both sides of the proverbial table help her provide you with the information you need to achieve your goals. She was always available, (even over the Thanksgiving weekend). She valued our time which is very limited. She accommodated our crazy schedule and made this happen. We found exactly what we were looking for and with her advice, our offer, which was one of several, was accepted. She attended to every detail in a truly professional manner. We can not say enough about her and recommend her without hesitation to anyone seeking a first rate Realtor.
Betsy and Frank McGovern, Lexington, MA

"I met Mary-Lou at an Open House. My husband and I were looking for a Realtor but had no luck finding one that understood us. Then I met Mary-Lou and was so impressed! First and foremost, Mary-Lou was professional and knowledgeable She was very nice to my small, impatient children and that meant a great deal to me. I called her a few days later and we began our journey for my family’s first home together.

Throughout our search Mary-Lou was fantastic – always responding quickly to e-mails, phone calls and texts. She gave her opinion when appropriate and never pressured my husband and I in any way. Mary-Lou was so patient, understanding and willing to do whatever it took (scouring hundreds of MLS listings!!) to find a beautiful home for my family.

My family bought our first home in Lynnfield and we are just over the moon delighted! When we viewed the house for the first time Mary-Lou knocked on neighbors’ doors and asked questions to find out about our potential new neighborhood.

I would highly recommend Mary-Lou to all of my family and friends. She is a gem and my daughter and son call "Ms. Mary-Lou” their friend!

"Mary-Lou guided us through the process of buying our first house. We felt that she immediately understood what we were looking for and was able to help us identify houses that would be a good match for us. We were all working as a team towards the same goal, which was to find a house that we would LOVE!”

"Mary-Lou is hard-working, knowledgeable, professional, responsive and well-connected. It was truly a pleasure to work with her. We would absolutely recommend Mary-Lou to family and friends looking for an excellent Realtor!”

Bryan & Margaret McQuade, Buyers

"Mary-Lou was enormously helpful to us in marketing and selling our house in Lexington. She was generous with her time, candid in her counsel, strategic in execution, and always encouraging and supportive. She was also extremely helpful in identifying a team of experts to help with preparation of the house for sale – a painter, carpenter, ‘junk’ disposal expert, stager, and attorney, as well as organizing opportunities for many other brokers to see the house and offer their own best advice. Finally, Mary-Lou couldn’t have been more helpful in the negotiating trenches once a potential buyer had been identified. I would recommend her without reservation.”
Charlie Marz, Seller

"If you are in need of a realtor who… will listen to you; make great recommendations to get the best price for your house; be available to you as if you are her only client; is someone who truly cares like it’s her house she’s selling; and… will bend over backwards to help you get your house ready to put on the market; then Mary-Lou McDonough is the realtor for you! Mary-Lou and I worked together last year to sell my 4-bedroom home in Lexington and help me find a fabulous townhouse condo as I was downsizing.”

Not only did she do the things you expect from a realtor, she helped me clean out my basement! Yes, she did that and she made the unpleasant job fun! When I was stressed, she calmed me down. When an enormous tree fell against the back of my house 3 days before the buyer was coming for final inspection, she made sure that tree was removed in time. She kept me informed every step of the way. As we all know, selling your home and moving is a very stressful task. Mary-Lou got me through it and if I have to do it again, she’s the first and only person I will call.”

I recommend Mary-Lou to my friends, family, professional contacts and anyone who needs a truly honest, professional, detail-oriented, thoughtful and delightful person to sell your existing home and help you find your new home.”

Pat Magrath, Seller/Buyer

"Mary-Lou was professional, knowledgeable and dependable throughout the entirety of our selling process. She exceeded our expectations, and we highly recommend her.”
Eric & Jessica S., Sellers

"I chose Mary-Lou as our agent because I attended several open houses in Lexington and met many realtors at these event. Mary-Lou was the only agent that I met during this process who offered specific information on the community and schools as it related to my family.

"Mary-Lou helped make our relocation process from the west coast to Lexington very easy. Mary-Lou is professional, efficient, easy to work with and nice to spend time with. She exceeded my expectations for a real estate agent. She was available to show me homes based on my very limited schedule. She listened to our needs and helped me find a home that is perfect for my family. Mary-Lou is very knowledgeable about the area. She helped us get information on the public schools for my 3 children, recommended several contractors to work on our new home home, and recommended bankers and attorneys to help our transaction run smoothly. Her long term commitment to this community was very obvious to me and her years of experience saved us a lot of headaches and extra work. Mary-Lou went above and beyond in handling many of the transaction’s hassles and helped keep our end of the process and closing easy and as stress free as possible. I would highly recommend Mary-Lou to any family or friends who need to buy or sell a house.”

Barbara & Andrew White, Buyers

"Mary-Lou is a highly responsible person. She has tried her best to work towards our benefits and protect our interests. I really appreciate that she has been very patient with us. After working with her for 3 years and 3 transactions, I feel she is not just our agent, but she has become a friend. If I have future opportunity to purchase a home again, I will not turn to anyone else but Mary-Lou for help. I definitely highly recommend her to any of my friends who are ready to purchase a home.”
Sally Suen & Qiao Zhou, Buyers

"Mary-Lou was the listing Realtor for our home in Lexington. She helped us prepare our house for sale, using her knowledge and loyal resources – who were available within days to paint or repair whatever was needed to make the house sparkle for showings. The selling strategy worked effectively and we received several offers. Throughout the process, Mary-Lou was informative, available and understanding of our needs. I’d describe Mary-Lou has a Realtor who goes above and beyond to meet the needs of her clients. She’s also a very kind, empathetic and warm person to guide you through the process of selling your home.

"I’d highly recommend (and have recommended) her to friends selling or buying a home.”

Rochelle Sharit & Wayne Pastel, Sellers

"Mary-Lou McDonough is so much more than a real estate agent. My sister and I recently sold my elderly parents’ home in Lexington. Mary-Lou made this stressful, daunting task so much less difficult for us. She is experienced and knowledgeable about all aspects of selling a home. She provided staging advice and recommended many people who were able to quickly and competently fix the multitude of issues that had been neglected in my parents’ home. I lost little time from my workday because of her willingness to help with all the details. She responded very promptly to calls, texts and emails. It was a pleasure to work with her and I’d recommend her to any friend or relative buying or selling a home.”
Anne Ingard, Seller

I must admit I am one of those people that have heard it’s a sellers’ market and took that to mean I could stick a sign in the ground and people would flock to me waving their check books. After meeting with Mary-Lou I realized there was a lot more to it than that. While I may not have been receptive to her suggestions at first I’m grateful she was able to demonstrate how important it was to leave the marketing to the professionals and Mary-Lou is the quintessential professional. Mary-Lou showed us exactly where it was worth spending some time and money to showcase the house, guided us through the negotiating process and brought us a great buyer. I can’t thank her enough for all she did for us to get our house sold quickly and for top dollar. We owe it all to Mary-Lou!
