"We worked with Mark on the sale of one home and the purchase of another. Both transactions required an exceptional broker to complete effectively. In fact, I do not think we could have sold our home with any broker other than Mark. He was able to manage the various parties to the transaction to get done what needed to get done so we could close in a timely manner. We left it all in his hands and he got the job done. When we returned to the area, it was only natural that we would select Mark to represent us as a buyer broker. We found a property we liked and made an offer. Mark managed the transaction and got it back on track after it derailed midway through the process. I would not hesitate to recommend Mark for any real estate transaction you are contemplating, no matter how challenging it may be."
Dave and Kathy R. (Medfield)

"I had been looking on and off for a home when I met Mark at an open house he was hosting at a Canton condo complex he was selling. The condos were new and nice, but they weren't the right fit for me. Mark worked with me to look at property that suited me better. He listened to what I liked and made recommendations as to where we might find it. I almost bought a condo in Weymouth, but then we found my home in Hingham. It had just come on the market. We made an offer right away. There were a few inspection issues we had to work through. Mark helped me with those. He also helped me find a local builder who added a second floor to my home. The project turned out beautifully, although it was a bit stressful at times. Since then I have recommended Mark to several friends, one of whom he has helped buy a home in Hull. I enjoyed working with Mark and will work with him again on my next real estate transaction."
Rachael B. (Hingham)

"Mark helped us purchase a home when my company relocated me to Boston. We had never lived in the area before. Mark helped us search in various towns, including Newton, Needham, and Wellesley. We found a home in Needham we liked. It was new to the market. Mark evaluated the location and its long term prospects for maintaining value. He encouraged us to make an offer. We bought the home for $790,000. Shortly after we bought, the entire market declined. Fortunately for us, when we went to sell our location had increased in value. We sold the home for $835,000. We were grateful to Mark that we had chosen the right location since it held its value while others did not. I would recommend checking with Mark before you buy or sell any property."
Ruben and Somarly A. (Needham)

"Mark helped us sell our house in Newton. It was a beautiful home on one of the best streets in town, but the market had just turned down and the industry was going through a transition. Hence the sale was a challenge. Mark put together an excellent marketing package with his firm and gave us the exposure we needed to get many showings. We had already relocated which complicated matters slightly since the house was empty, but Mark had a few rooms staged and that helped with the presentation of the property. Being local to Newton, Mark was able to handle showings on short notice. We hit a few road blocks in the sales process. Mark was available, along with the professionals he had recommended, to us to assist us in clearing them and all the way through the closing. We are grateful for his assistance and would work with him again in the future."
John and Consuelo P. (Newton)

"After looking for a new home for many months, both on my own and with other agents, I was starting to think I'd never find the right place for my current needs. A colleague who had worked with Mark to buy her home suggested I contact him to give my search a boost. I had narrowed my search to Newton and Natick, but there was very little inventory on the market at the time. Despite this, Mark listened closely to what I said I was looking for and was deliberate about showing me homes that he knew would meet my needs. I appreciated that he had a specific process, which gave me confidence in his professional skills, and also that he was tuned into what I said I wanted as a buyer. Within a few short weeks, we found the home I'd been looking for, and Mark helped me navigate every stage of the purchase. He advised me on making a competitive offer in a multi-bid situation, provided me with resources like options for home inspection as well as directed me toward the appropriate town offices where I needed to do some research prior to the purchase. Each of these small touches saved me time and energy during a busy time. Even after I closed on the property, Mark gave me invaluable advice on increasing the value of the home through strategic updates and improvements. This is the third home I have purchased, and so I have some experience with real estate transactions. Nonetheless, Mark was a valuable resource to me and made the process easier. I wouldn't hesitate to work with Mark again and recommend him, even if you are a seasoned real estate buyer."
Emily H. (Natick)

"Mark has listed, sold, and rented over 50 properties for me since I first met him in 2006. These properties have included condos and single family homes as well as mixed use and multi-family properties. Overall, he has done a great job. His work ethic is good. He is honest, knowledgeable, thorough, and effective. I would not hesitate to recommend Mark to assist you with all your real estate needs."
John M. (Massachusetts)

"We wanted to move closer to Boston and engaged Mark to help us find a home. He set up a systematic search process for us. We looked at homes throughout Metro West Boston and identified one in Southborough with Mark's help. It was a complicated transaction that required multiple inspections and approvals before we could proceed. Mark patiently guided us through the steps and connected us with professionals who helped us in various areas. We were able to close in a timely manner and ended up getting a great deal for the space we acquired. We are grateful to Mark and would recommend him to anyone seeking to buy or sell real estate."
Brendan and Mary Beth Mahoney (Southborough)

"When we relocated to the Boston area, Mark and his firm helped us find a rental property in Brookline, close to our work. It was a convenient location but, as our family grew, we knew we needed a house. Mark coordinated our search for us in Newton and Brookline as we requested but suggested us to check out also Needham, a bit further but with more space for our bucks. We ended up buying a property in Needham within walking distance to school and the train. It has been a great investment for us. Our neighborhood has grown in value since we bought our home. Now we are thinking of investing in an addition to our home or buying a larger one. Mark has helped us with the economic analysis of these options and is helping us to see what is on the market that can satisfy our needs. Whichever solution we will choose, we are and will be grateful to Mark for his expertise and assistance. Knowing that we can trust him and realizing how much he knows of the continuously changing situation of the market around Boston is important when you have to make a decision like buying home."
Aldo and Tiziana R. (Needham)

"We were renting in Chestnut Hill when we met Mark. At the time, we were expecting an addition to our family and wanted to invest in a property nearby that provided us with more space. Mark coordinated our search and helped us identify a two family home in West Roxbury that suited our needs. The property needed work, but the bones were good. It was a complicated transaction, a short sale with two lenders that needed to be paid off. At the last minute, Mark was able to connect us with a mortgage company that was willing to finance the transaction for us when our original lender was unable to get it done. We are grateful to Mark for his assistance and expertise in completing the transaction. If you are dealing with a complicated real estate transaction, we encourage you to give Mark a call. He can help you out."
Ari W. (West Roxbury)

"Mark helped us move from Somerville to Framingham. He lined up several property tours for us in towns of interest and accompanied us as we visited each home. His experience and knowledge helped us make the right buying decision. Once we had bought our new home, Mark sold our condo for us in Somerville. His always being available to help saved us time and expense. We would recommend Mark for your next move."
Seth & Jessica S. (Framingham / Somerville)

"We began our search looking in several Metro-West towns. Mark helped us narrow and refine our search, given the criteria we gave him. Newton emerged as a destination city for us compared to the other markets we were evaluating. As a Newton resident, Mark helped us understand the different Newton mini real estate markets well. When a home came on in a mini market we desired, Mark helped us design an offer that worked. We successfully outmaneuvered 10 other buyers and bought a great home at a great price in a great location. We are grateful to Mark for his assistance. His knowledge, experience, and effort helped us make a better real estate decision than we would have without him."
Newton Buyer (Newton)

"When we decided to make a move out of our one bedroom condo, we contacted William Raveis Real Estate since they had sold units in the area. The firm recommended Mark. Mark helped us present our unit in a very favorable light vs. other comparable units on the market. He hired a floor plan professional and a high-end wedding photographer to measure and photograph our unit. They did a great job! Our unit showed extremely well compared to our competition. This step, along with a pricing strategy that generated five offers, allowed us to negotiate the best deal possible. Mark "brought us the market" and we decided how to proceed. The whole deal process worked well and went smoothly. We would recommend Mark to anyone looking for help with their real estate needs."

Scott and Sarah Zerneri (Brighton, MA)

"Mark is a five star real estate agent who knows the greater Boston area extremely well and helped my wife and I perfectly to get a great home for a good price in a a highly desired neighborhood in Boston. Mark guided us through the whole process and made sure that we always felt confident with our decisions. We would work with Mark any time again."
Alex Wriedt (South Boston)

"Our experience with Mark was consistent from start to finish. He is ultimately who you would want on your side. His manners, professionalism and approachability made our home selling process very smooth and pleasant. He showed up with data about pricing, timing, market conditions, etc. and ushered us through the process with ease. We could sum up our experience as ?no stress? and ?productive?."
Ash Sirivallop (Natick)

"Mark recently helped us sell our family home which had been in our family for almost 100 years. Situated on a scenic road in beautiful South Natick, our home was built around 1880 on just over 2.5 acres of land. The sale was difficult since the house was older and in need of some updates to make it competitive in the current marketplace. Mark helped us develop a pricing strategy that incorporated the need for these updates. He put together a professional presentation which generated 4 offers. Then, he helped us select the best offer and guided us through the process. It was a bumpy road, but Mark helped us keep the deal on track and get to closing. We are grateful for his hard work and perseverance. In the end, we got the price Mark said we would get. He knew the market and how to navigate through it. If you are looking for help with a complex real estate transaction, we recommend you give Mark a call."
Liz Maisey (South Natick)

"Mark managed the entire process from start to finish and exceeded our expectations. He met with us to outline the process. He began to send us listings based on our likes. We saw one. We visited the Open House, and we knew that it was the one. He suggested an offer that he thought would get the deal done. He hand delivered the offer to the seller's agent, and our offer was accepted on the house within 3 hours. We saw one house, we made one offer, and we found our family's home. He wasn't done there. We had financing lined up but he connected us with a loan officer, and we were able to get a much better deal. He lined up a thorough inspector. And, he was able to beat our original home owner's insurance quote. He saved us time, money, and worry. I could not recommend Mark more"
Ben Rubeor (Walpole)

"Mark helped us find and purchase a new home in January 2020. As first time home buyers, we were initially nervous about taking this next big step in our lives, but Mark provided friendly and reliable guidance, simplifying what otherwise could be a stressful and harrowing process. He first met us for dinner in May of last year after our baby was born (he brought pizza to our apartment!) and provided us with several resources for purchasing a home, including a book that he wrote - Better Real Estate Decisions: Tips for Sellers, Buyers, and Novice Investors. I found Mark's book and the accompanying playbook very useful for understanding the home buying process - ie, avoiding common pitfalls, knowing what to look for in an asset, not sweating the small stuff, etc. Over the course of several months, we became pre-approved and began looking at houses. Mark helped us practice and develop the right skillset for assessing a home?s value. Over time, we became comfortable with determining which open houses were worth attending, and which ones weren?t. There were a few houses that we wanted to make an offer on which did not pursue because we stay disciplined and continue building our skills. In hindsight, that was the right decision, and Mark gave us good advice. Mark sent us the listing to the house we now own. It was love at first sight. From the offer to the closing was roughly 60 days, so things moved pretty quickly, but Mark kept us on top of things. As it turns out, the sellers had their (shall we say) ?quirks? (the listing agent was periodically in Ireland, the seller?s attorney was periodically in Washington DC, the seller made some odd requests about what to leave/take) Through it all, Mark was a steady hand and was quick to follow up, ensuring we had everything squared away for the closing. The closing was very smooth, a testament to the hard work we put in during the weeks leading to that date. Finally, after the home was purchased, Mark took us out to dinner to celebrate! Throughout it all, Mark empathized with us, understood our needs, and continuously delivered excellent service and subject matter expertise. I mean it when I say we couldn?t have done it without him. We are happily living in our new home and neighborhood, thanks to Mark. Thanks Mark!"
Maggie Keefe (Millis, MA)

Mark O'Donnell sent a postcard, offering a complimentary evaluation of my home in Newton Centre, MA 02459. Several days after he came, he brought a detailed report, showing nine "comps" (comparable homes), in my neighborhood, which sold in the last six months. His analysis was detailed and precise. He explained what strategy he would recommend, when I am ready to sell. He gave me a copy of his book, "Better Real Estate Decisions: Tips for Sellers, Buyers and Novice Investors". I am very impressed with Mr. O'Donnell's breadth of knowledge and experience.

Helen Henkle Aguirre (Framingham, MA)

"We reached out to Mark back in January at the start of our home buying process. He provided us with key resource materials prior to the house hunt which helped us prepare for the strenuous process of house hunting & purchasing! We visited several open houses and were still unsure of the area. Mark was very professional and knowledgeable of the towns we were interested in. He helped us by letting us know about the neighborhoods, things to look for and to avoid as we had young kids. We were very happy we used Mark, as he made the process easy to follow, and was there with us every step of the way. We happened to start looking before the pandemic had begun and Mark helped us maneuver through the process seamlessly and without a hitch. He also referred us to a great lender and attorney who we ended up working with during this process. I highly recommend Mark - He will make the process easy to follow through and in YOUR best interest."
Carlton Vaz

"Mark helped us in our selling/buying process which was a huge success. We ended up with a house that we love, selling our house quickly and at a very good price. At all times he did a good job managing expectations, conveying our position and needs. Thanks, Mark!"
Santiago Silveyra (Holliston, MA)

"Mark is super helpful and knowledgeable. Very lucky to have him as our agent who helped us win our dream house from a group of competitive bidders. He is responsive and has always been around throughout the closing process. Very pleasant experience to work with him!"
Sherry (Lexington, MA)

"Our experience with Mark was very good. He was introduced by a good colleague of mine. My wife and I were specifically looking at Lexington and Newton because we were looking for good school districts and my wife and I were both new home buyers. Mark was very patient with us to walk through the specifics and gave us tips about what to watch out for in a house. For example, he pointed out we should be careful about buried oil tanks. Mark spent the time with us in the town hall to make sure the previous home-owner had the proper permits. In addition, Mark would advice and tailor each offer we make, and he's willing to hustle and work on the sellers and seller's agent to get our offer accepted. In the end, we were able to close on a house of our dream and we can't wait to start our little family there! Over all Mark is very patient, knowledgeable, dedicated, and responsive. He has a deep knowledge in the real estate market of the Boston metro area. I would highly recommend Mark for anyone who is looking for a smooth home purchase experiences."
Vincent (Lexington, MA)

"Mark did an excellent job. He was professional, thoughtful, and successful. I will recommend him in future."

Athene Sirivallop (Natck, MA)

"Working with our agent was fantastic. His knowledge and willingness to meet anywhere anytime was awesome. He relieved many of the pressures of home buying with his easy going and professional approach."
Philip Derendorf (ANDOVERMadbury, MA)

"Mark was very helpful in helping me purchase my home. He was excellent about finding houses in the neighborhoods I was looking at as well as suggesting other areas I may not have considered, and was very helpful in guiding me through the open houses until I found my house. His insight and expertise were invaluable to me as I was submitting my offer. In a sellers market Mark guided me to finding my house at a price that was very reasonable. He was very responsive and knowledgable and without his guidance, I may still be looking for a house. I highly recommend Mark, he is a true professional."
James Norton (West Roxbury, MA)

"Mark was exceptional. We listed the house just as COVID-19 hit and he was extremely responsive to the care and health concerns we had for showing the house. He rigorously screened buyers for only viable candidates, was extremely careful to communicate visits and always paid attention to see CDC guidance for our health and safety. We could not have been more pleased given the pandemic circumstances."
Thomas Haferd (Medway, MA)

"We bought and sold our home with William Raveis. They were very professional, knowledgeable and very helpful every step of the way. They sold our home above asking with 9 offers to choose from. When we bought our home, the agent was extremely helpful giving us market analysis of the property as well as negotiating. Overall, we highly recommend working with William Raveis and with Mark."
Carlton Vaz (Stoughton, MA)

"Condo was put on the marked. We had about 10 open houses. I receive one offer, it fell through because the man had a cat. I received a second offer 7 weeks after it was listed. There was a special assessment on the property that complicated the sales process. Mark did a good job explaining it to potential buyers and eventually he found a good cash buyer who closed."
Kristina Roddy (Arlington, MA)

"Mark O'Donnell is an excellent agent. Highly recommend!"
Nicholas Wells (Mount Vernon, NY)

"Mark was very dedicated, hardworking, and detail oriented. He helped us to find a great home!"
