Mike went above and beyond with our quest. We had a narrow scope and he was there to answer our most inane questions. Eventually guiding us to our current home (just 5 minutes from our old house. He was a pleasure to work with and I would recommend him highly to anyone searching for a home in MA.
Mike O'Brien was an amazing realtor that went above and beyond to help me find my new own. After having multiple discouraging experiences with realtors, he was a breath of fresh air that told me finding my new home, in the area I wanted, was possible. Not only did he support and help me find my new home, in my ideal area, he marketed and sold my existing condo in one of the fastest turn arounds ever. He went above and beyond to make sure I was comfortable with the process from start to finish, and responded quickly to my many many questions. I highly recommend him for your realtor needs and know I will for sure be using him again when real estate needs arise!
Mike O'Brien is an outstanding realtor. Mike helped me sell my brother's condo from another state. He went above and beyond in coordinating all that needed to be done to put the property on the market. He was right on target what needed to be done and what things future owners would probably want to decide for themselves. Mike communicated with me through the whole process and was always available. My brother sold his condo for more than we ever imagined. I highly recommend Mike O'Brien.
Mike did a great job for me. He walked me through the process and got me a great price for my condo. I wouldn't hesitate to recommend him. He could not have made the process any easier. Process was very easy.
Mike was our agent as first-time home buyers. He was extremely knowledgeable and professional. He spent great amount of time educating us on the home buying process during the entire process. Our first meeting he walked through the home buying process with presentations and a detailed walkthrough explaining each step of along the way highlighting key milestones.He really follows his mantra - 'Your timeline is my timeline'. This really resonated with us because he ensured that we were comfortable financially and emotionally to buy our first home. Mike was extremely efficient in communicating the situation and was honest during our every discussion. Post offer acceptance, he provided very valuable contacts of Attorneys, Home inspectors etc making our closing processes extremely easy. Each of the contacts that he gave provided excellent service and were an extremely efficient team. So much so that we were able to complete and coordinate the process whilst being on international vacation only by checking emails and text messages periodically. Once all paperwork was done, Mike offered his insights and useful opinion on upgrades to the home citing his personal experiences. Mike made the home buying process a lot of fun with witty banter and comic relief during our home search. We highly recommend Mike especially for First time home buyers.
I had a great experience with Mike working to buy my first home. Mike was incredibly responsive, always available to answer questions on a quick call or sit down for a longer zoom to plan for the big picture. He was an excellent sounding board for navigating making offers, and once I had an offer accepted, he came up with many creative solutions to work through a challenging closing process. I'm very grateful to have had Mike on my team!
Being first-time home buyers, my wife and I found a trustable person that could help us understand and become comfortable with the home-buying process. The first step was so solid that we were very confident delving into the process without much fear. Throughout the process, we felt that we had a safety net to fall back on if things were to go down south. We visited around 50 properties (both open houses and private showings included) before settling on one and Mike was present for pretty much all of them and never showed any signs of frustration. He guided us well and helped us move past many houses that in the hindsight wouldn't have been worthy investments for us. The only thing we wish could've happened better for us was working with a different closing attorney than the one suggested by Mike. However, Mike chimed in at the right moment to resolve some turbulence during the closing process. Overall, it was a great experience working with Mike and getting to know him. I would recommend Mike to anyone who wants their home-buying process to be enjoyable and stress-free
Our purchase was complicated by selling a property in another state, so the timing was of the essence. Mike was professional and extremely responsive, even with the added issue of being in different time zones. We highly recommend him with confidence. We are looking forward to working with him again.
Mike was able to get us through a difficult buying experience and reach the finish line! We found a property we loved, and there were many roadblocks along the way, but Mike was able to communicate and take the work off of us in the back and forth and determination of next steps. He worked with our lawyer and mortgage lender seamlessly and was always easy to reach. There was never a time we felt like we couldn't communicate with Mike which was so important to us. He always was interested and caring about what we had going on. Thanks Mike!
Mike was wonderful throughout our house-hunting process. It took us time to figure out exactly what we wanted/needed, and his patience was impressive. He was there to listen, and also offer guidance as appropriate. He was especially adept at intervening when my husband and I got "too excited" about a particular property and were overlooking important aspects. Real estate transactions can be very stressful, and Mike's warmth and wit are true assets. I highly recommend Mike O'Brien as someone who can guide you through the process.
As a first time home seller, I could not imagine going through this process with anyone other than Mike O'Brien. Incredibly easy to work with and a GREAT attitude overall. I was selling a unit with current tenants and Mike was always considerate of their time and needs as well as mine which was important to me. Quick to respond to my multiple questions, Mike truly made this a completely seamless process and his selling strategy earned me an offer nearly 10% over asking! TL;DR - Hire Mike O'Brien as your realtor immediately
Mike was great to work with! As a first time buyer, he very clearly explained the game plan and what I should expect at each step of the process. We quickly got on the same page about what I was looking for, and honed my search accordingly. He was always available for any questions that came up and very responsive over email, text, and phone. He kept me updated with things I needed to know, and worked on things behind the scenes to keep things moving smoothly. Overall a great first buying experience and a great agent to work with!
Mike was very great to work with! Highly recommend if you are looking for a relator. He was always available by cell and continued to check in to make sure everything was settled. Definitely trustworthy and pays close attention to detail.
I have worked with multiple agents in the past, and I have to say Mike is the best. Very knowledgeable, helpful, and most importantly available always to answer questions. Made my real estate purchase an easy, pleasant experience.
Mike was absolutely amazing! I did a big, cross country move from Miami to Boston. Once he received my contact information he reached out right away to figure out exactly what I needed. He worked quickly to find me multiple options and started setting up virtual showings for me. He understood I was moving in a hurry and was able to find me multiple properties that fit my needs within my budget. He went to showings for me, walking me around on his iPad as my personal avatar. He tested out all of the lighting and water pressures and got to know exactly what I was looking for in each place to the point that he would just test those things out and show me before I even asked! Mike was always available for calls and texts and got back to me quickly whenever I reached out. He was so easy and fun to work with and was able to handle my big, opinionated family's questions and concerns with grace and humor. Once we decided on this beautiful property he handled all of the negotiations, getting me a stellar deal, the perfect location, and the apartment of my dreams! With moving already being a stressful process, I thought moving across the country would definitely be the most stressful thing, but Mike made it seamless and I'd do it again in a heart beat with his assistance. I definitely recommend working with Mike, know I'll be recommending him to all my friends and family, and if I'm moving again he'll be my first call!
