Zack Harwood Real Estate operates under Berkshire Hathaway HomeServices Warren Residential on Boylston Street in Boston, working alongside business partner Carly Harwood across Greater Boston — reviews name Cambridge, Somerville, West Roxbury, Framingham, and towns north and west of the city like Woburn, Wilmington, Burlington, Reading, Medford, and Waltham. The written record is deep — 141 reviews since 2021 across three sources, currently a 5★ average on Google from 187 ratings — and specific transactions keep surfacing rather than just adjectives. A May 2026 review describes selling a client's condo and closing on their new townhouse within a week of each other. A December 2025 review credits Zack with acting as the go-between with a builder on a new-construction purchase, walking a first-time new-construction buyer through the process. A June 2025 review says he set up daily listing emails that made a big difference for an out-of-state buyer, and a September 2025 review describes him orchestrating closing through what the reviewer calls a bumpy lending process. In a 2024 review, a Connecticut-based client describes a nine-month remote search for their son's Boston residence, saying Zack never missed a beat sending properties and updates. Several reviewers are repeat clients. A January 2025 review says it was the reviewer's third time working with Zack's team — this time to identify upgrades that would strengthen a home's listing before it went to market — and an April 2025 review similarly describes working with him multiple times over the years. Carly Harwood shows up independently across a large share of the reviews, particularly guiding first-time buyers in towns like Woburn and Framingham. Nothing negative shows up anywhere in the written record, across five years and three sources. For a Greater Boston purchase or sale — especially a first-time buy, where the volume of reviews describing patient, detail-heavy handling is heaviest — this is a well-documented team with a long track record and nothing on the record to weigh against it; the main variable is which of the two partners you end up working with.
Zack Harwood was a true professional to work with and made what could have been a complicated and stressful endeavor….a smooth and seamless transaction. He was courteous, knowledgeable, responsive and addressed our personal concerns in a way that brought insight and order. This allowed for good decision making. I would absolutely recommend him for your Real Estate needs.
We worked with Zack to sell our condo and buy a new townhouse. He made the process seamless working through timelines to make both sales happen within a week of each other! Zack is very knowledgeable about the local market but also helped us to navigate unique situations and overcome any challenges that were presented to us!
Zack was an incredible realtor to work with throughout our first home buying experience. He was extremely attentive, knowledgeable, and communicative without ever being pushy. No matter what questions came up, he was always available and took the time to guide us through every step of the process with patience and professionalism. As first-time homebuyers, we were new to everything, and Zack truly helped make the process feel smooth from start to finish. He kept us on top of deadlines, coordinated with attorneys, our mortgage team, and the seller, and advocated for us every step of the way. Buying a home can be overwhelming, but Zack made it feel manageable and organized. Even the seller commented that we were one of the easiest and best buyers she had worked with, which we know was largely because of how well Zack guided the process behind the scenes. We’re grateful for all of his help and would highly recommend Zack Harwood Realty to anyone looking to buy or sell a home!
Zack was tremendously helpful in the process to buy my first house. He was knowledgeable about the market, made the process super easy and smooth and was proactive about helping me understand the process. Would recommend him to anyone who's looking for an agent!
I've known Carly for quite some time, and when my husband and I started to consider buying a home, she was the first person I contacted. Carly was unbelievably knowledgeable and reassuring throughout the entire process. As first-time homebuyers, we had lots of questions! Carly always had - or found - the answer. She was present, reliable, and, without a doubt, the reason our 30-day contract to closing went so smoothly. We are so grateful to Carly and the team at Berkshire Hathaway.
