Zack Harwood Real Estate at Berkshire Hathaway HomeServices Warren Residential

A condo sold and a townhouse bought inside the same week — that is what one client says this team pulled off for them in May, threading two sets of timelines together so neither closing slipped. Zack Harwood Real Estate is a two-agent operation working Boston and the towns around it: Zack Harwood, who by his own account was a buyer for HomeGoods before he moved into real estate, and Senior Sales Associate Carly. They operate under the Berkshire Hathaway HomeServices brokerage, out of an office on Boylston Street in Back Bay. By the team's own count, 2025 brought 55 closings totaling roughly $48.1 million. The territory they name runs from Back Bay, Beacon Hill and the South End out through Brighton, Dorchester, East Boston, Jamaica Plain and South Boston, plus Brookline, Cambridge and the wider Greater Boston suburbs. Almost everyone who writes about them is buying a first home. Across 141 reviews stretching from 2021 into 2026 on three different sites — including 187 Google ratings averaging five stars — the same arc keeps repeating: someone who has never done this before, a long run of showings, and an agent who explains what happens next before it happens. A buyer this May put the useful part plainly: attentive and communicative "without ever being pushy," with deadlines tracked and the attorney, the mortgage team and the seller all kept in step. Another buyer that same month, also purchasing a first house, described the same proactive walk-through of each stage, and in April a first-time buyer said Carly was the first call she made when she and her husband started looking. Two things are worth pinning down before you sign anything. This is two agents, not one, and a real share of the praise belongs to Carly rather than Zack — so ask who will actually run your search, attend your showings and sit at your closing. And the sales totals are the team's own published numbers; the independently visible part of their history is the review trail, which leans heavily toward purchases. Sellers do appear, like the May client who sold a condo while buying, but buying is what most of these accounts describe. If you are a first-time buyer in Boston or a nearby suburb, this is a sensible call: the recurring praise is for pacing, plain explanation, and not being pushed toward an offer. Ask at the first meeting which of the two agents you will be working with, and have them walk you through what they have closed lately in the specific neighborhood you are targeting.
