Three markets people weigh against each other constantly, for completely different reasons. Here is what each one actually offers, with real numbers, and who each one is genuinely for.
Somerville: density, transit, and triple-decker conversions
The money. Sources put the median somewhere between roughly $950,000 and $1,000,000. One June snapshot had single-family houses at a $1,245,000 median with condos at $775,000; another had the overall median at $1,000,000 with homes selling in about 21 days. Condos average around $921,000 with median listings closer to $799,000. Single-families are rare and pricey, averaging around $1.64 million on urban lots mostly under 4,000 square feet. Two- and three-families average around $1.49 million.
What changed. The Green Line Extension — 4.3 miles, $2.28 billion, opened in two phases in 2022, with stations at Union Square, East Somerville, Gilman Square, Magoun Square, and Ball Square. Projected ridership around 45,000 one-way trips a day by 2030. Winter Hill single-family values run around $816,000 and East Somerville medians around $880,000, both now with direct Green Line service. That is where the purchasing power is.
The product. Condos in converted triple-deckers dominate — exposed brick, refinished floors, opened kitchens, central air added at conversion, in-unit laundry. Conversion quality here is genuinely strong. But roughly 21 percent of recent buyers waived inspection and 19 percent waived appraisal, and I would be careful about waiving inspection on a triple-decker conversion, where finishes tell you nothing about the structure behind them.
The tax break. Somerville's FY2026 residential exemption removed $416,961 of assessed value at a $10.98 rate — worth roughly $4,578 a year. File by April 1.
For: People who want density and walkability, who work in Cambridge or the biotech corridor, and who want real square footage in a conversion rather than a small unit in a big building. Also house-hackers, since two- and three-families here work.
Not for: Anyone who needs easy parking or wants a yard.
Brookline: the family answer, at the family price
The money. Recent data puts the median between about $1,155,000 and $1.3 million depending on window and source, with price per square foot around $797 and average home value near $1.18 million. Inventory was up 17.1 percent year over year in June, and one three-month measure showed the median down almost 13 percent while the average last month was up 18.6 percent.
Those numbers only look contradictory. They tell you Brookline's market is pulled around by mix — single-families drive the median far above condos, and a few high-end closings move the average. The town-wide median is close to useless here. Use village-level, product-specific comps.
Competitiveness. Homes have sold in roughly 21 to 30 days, 98 percent within 90 days, and 90 percent for over 95 percent of list.
The villages. Coolidge Corner for walkable, car-light family life on the C branch. Brookline Village on the D branch, which matters enormously for anyone working in Longwood. Chestnut Hill and the west end for larger lots and higher prices. Washington Square as the relative value zone.
The catch nobody mentions. The housing stock is overwhelmingly pre-1978. Under the Massachusetts Lead Law, any home built before 1978 is assumed to contain lead paint unless proven otherwise, and if a child under six will live there, the owner must have it deleaded or brought into Interim Control within 90 days of taking title. Ask for a Letter of Compliance before you fall in love. Deleading runs from a few thousand for targeted work to well over $10,000 for a full unit; the state credit is up to $3,000.
For: Families who want the district, the walkability, and separate-town governance, and who can carry the price. Also anyone working in Longwood.
Not for: Buyers without children who do not want to pay the school-district premium they will pay anyway, or anyone planning significant exterior renovation in a historic district.
Dorchester: space per dollar, and the only place the house-hack still pencils
The money. Recent data puts the median in the $600,000 to $725,000 range — one measure at $710,000, another at $602,500 with 15 days on market — at roughly $516 to $517 per square foot. Against a citywide Boston figure near $675 per square foot, with Beacon Hill and the Seaport above $1,100.
The product. The triple-decker defines it. A converted unit typically offers over 1,000 square feet with front and rear decks and shared yard access — compare that to a compact Back Bay unit at more than twice the price per foot with no outdoor space. A renovated two-bedroom in Savin Hill runs $550,000 to $750,000; new-construction three-bedrooms in Ashmont push past $900,000; a whole triple-decker near Savin Hill or Ashmont still trades in the $900,000 to $1.4 million range. Those numbers do not exist in JP, Somerville, or Charlestown.
Transit. Red Line at JFK/UMass, Savin Hill, Fields Corner, Shawmut, and Ashmont. The Ashmont-Mattapan line with Cedar Grove and Butler. And the Fairmount commuter rail through Uphams Corner, Four Corners/Geneva, and Talbot Avenue — consistently overlooked because people think of commuter rail as suburban.
It is not one place. Savin Hill, Ashmont Hill, Lower Mills, Cedar Grove, Fields Corner, Neponset, Adams Village, Uphams Corner. The differences between them exceed the differences between some separate towns. Housing quality varies block to block more than anywhere else in the city.
The strategy. Buy a two- or three-family, live in one unit. Owner-occupant financing, assistance programs that still reach this inventory under the $675,000 cap, Boston's residential exemption on the building — up to $4,353.74 for FY2026, which an absentee owner across the street does not get — and rents that hold because you are selling square footage rather than an address.
For: Value-focused buyers, anyone who wants space, and house-hackers willing to be landlords.
Not for: Anyone who needs the reputation to match the fundamentals, or who does not want the landlord job.
The one-line version
Somerville if you want density and transit and will pay near-Boston prices for it. Brookline if you are buying schools and separate-town governance and can carry $1.2 million-plus. Dorchester if you want square footage and the only version of the owner-occupied multifamily strategy that still pencils inside city limits.
The mistake is comparing them on price. They are three different products, and the same $900,000 buys a completely different life in each.
Tell me your budget, your commute, and whether you have kids, and I will tell you which of these three actually fits — including if the answer is none of them.
