About Collin Sullivan

"I was a first-time seller and Collin was able to anticipate my questions and concerns. He was very helpful by suggesting items to prepare my condo for sale .....painting, decluttering, and he arranged virtual staging to achieve top dollar for my unit. His marketing and signage is what ultimately brought the buyer to my see my unit. As a first-time seller, his confidence and professional advice put me at ease."

"As first time homebuyers, Collin Sullivan and team made for an exceptional experience. On a rainy Sunday in October 2020, Collin's colleague Dan met us at an open house for a condo we spotted in South End. Having been undecided on what neighborhood we wanted to call home, we continued to think about this visit for hours after. We thought it was a good sign and that we would need to act quickly given the volatility of the market. During the next week, Collin and team spent several hours coaching us on the first time home buying experience. From here, we decided to move swiftly on making an offer. Throughout the complex process of offer, acceptance, and final signatures, Collin's communication and attention to detail always let us take the passenger seat, which for a big decision was extremely comforting. One aspect of Collin's expertise we really appreciated is that regardless of budget, he made for a luxury experience. His prowess for the Boston real estate market is impressive and it was great to have him by our side as we took this big step. We would repeat the home buying process in a heartbeat, if it meant working with City to Suburbs once again. Thank you Collin for helping us to find our dream brownstone penthouse in South End!"

"It is with great enthusiasm and gratitude that I recommend Collin Sullivan to anyone looking to buy or sell residential property. Collin made my first home buying experience seamless. I feel lucky to have found him early in the buying process. I knew I wanted to buy a condo in the city, but did not know how to go about it. He took the time to sit with me and explain the entire process- from financing, to how to get pre-approved, to HOA fees, to the timeline from making a purchase offer to closing, and everything in between. I was blown away as this was all before we even started talking about my budget! It is always refreshing to find someone who truly loves what they do, and his passion and knowledge made the entire process fun. When it came to finding my home, he remembered all the little details in regards to what I like vs what I love vs what I can live without. He has excellent taste and during walk-throughs notices all the details I would have brushed by. Additionally, his wealth of knowledge on home maintenance and renovation further sets him apart. Even after I closed, he has been so supportive in helping me become a real homeowner. With his vast industry experience and knowledge and his honest and genuine nature, he will go to bat for you no matter your budget or needs. It is no wonder he is so successful. He is an absolute joy to work with and I can not recommend him enough!"

"Collin Sullivan and his team walked me through the process, showed extreme patients when I caused delays and facilitated when needed. We got an offer within 3 days of listing the property and Collin negotiated with them so I got full asking price. I strongly recommend Collin to help you sell your home or condo."
C.M. (Back Bay)

Collin embodies the rare mixture of personal grace and shrewdness in the extreme. He is a cordial individual whose manner invites openness and makes "thinking out loud" a pleasure. At the same time he is knowledgeable about the market, an experienced negotiator, and a candid communicator. Some combination.

"We have worked with Collin on 3 real estate transactions in the last year. In every case he has been exceptionally knowledgeable, helpful and professional. Highly recommend!"

"Collin is one of the most trustworthy, responsive, knowledgeable agents you will ever work with. He knows the Boston market and provided excellent guidance on pricing and marketing my condo to maximize value. He is highly experienced and asks insightful questions to uncover and anticipate customer's needs. My unit was on the market for 64 days from listing to sale! Both seller and buyers are very happy and you will be too if you work with Collin!"

"I have done several transactions with Collin now spanning 6 years. He has sold one house for me, last month and we have purchased together now twice. He is a professional of the highest order in a field where that is often hard to find! Collin has your best interest in mind with every negotiating round, holding the sellers and their agent accountable and keeping the transaction moving forward. He was able to get everything my wife and I requested in a home below our budget exceeding our expectations. He stays with the transaction all the way through including all visits to the property, meeting with contractors and vendors , inspections, and the closing. There are few agents that go this extra hundred miles for their clients. He is aces. If you are thinking of buying or selling a home and not thinking of Collin Sullivan then you either are uninformed or not thinking at all. He is simply the best agent one could have on their team as they go about what in most cases is the largest financial transaction in their portfolio."
Patricia Galloway (West Roxbury)

"Collin is an exceptional real estate agent. He is dedicated to his clients and will work hard to ensure they find a home that fits them perfectly. He is conscientious and has great attention to detail. His guidance throughout the entire home sale and home buying process was outstanding. We'll be calling him again next time we're ready to move!"
H. Prevost (Waltham)

"Collin Sullivan is one of the most knowledgeable, responsive and resourceful professionals I have worked with. The outstanding service he provided was beyond but related the sale of our property, including referrals to other competent professionals. As a result, Collin has made the rather stressful process of buying/selling one’s property a pleasant experience."
Delia Wolf (Newton, MA)

"Collin and Daniel are your real estate dream team. As a first time home buyer, I needed someone who was equally knowledgeable as they were patient. And Collin was exactly what I was looking for. He showed me every neighborhood from south end, to Dorchester, to JP and even up to Melrose. He pointed out flaws in homes I thought were perfect and asked the questions I didn’t know I needed to ask. <br /> <br />Buying my first house, really on my own, Collin and Dan made the whole thing a breeze. From putting me in touch with excellent mortgage and insurance companies to amazing real estate attorneys, they made the entire process easy and simple. Collin is also an absolute bulldog and will get the deal done for you. He estimates for what properties will go for or what would make a strong offer we’re spot on every time. He is truly excellent at his craft, and I look forward to listing my house with him in the future!"
Matthew Gluck

"Collin is an outstanding agent, providing expert advice throughout the search, construction and close process. We were able to conduct much of the 2+ year process virtually, only because of Collin's market knowledge and onsite coordination skills."
Jeffrey H. (Back Bay, Boston)

"A fantastic and smooth sales process in a slightly challenging market. Collin, my listing agent, executed the entire listing process flawlessly with excellent communication, branding and promotion. He did all he could to protect the integrity in our pricing and was able to close a deal more quickly than expected for an excellent return. Bravo!"
