Boston, MA Multifamily Market Report Q2 2026
Boston Pricing Hits a Record as Rent Growth Grinds to a Halt
Demand
Boston’s rent growth has gone quiet. Effective rent was flat at $3,162 in Q2, down just 0.05% YoY but a steep comedown from 3.52% growth a year ago. This is the softest reading since the market’s 2020 downturn. Vacancy told a better story, it rose 39bps to 3.91% YoY, down from 4.56% in Q1 as 3,984 units of net absorption outpaced a shrinking delivery pipeline. Occupied stock grew to 402,314 units even as employment growth remained negative for a second straight year, suggesting Boston’s demand base has more staying power than its labor market.
Supply
Unlike other markets, Boston never really had a boom-bust supply cycle and has been gradually normalizing. Completions fell 32.3% YoY in Q2 to 1,306 units, but the TTM total of 6,733 units is essentially unchanged from a year ago. What has changed is the forward pipeline: units under construction have fallen to 7,044 (1.68% of inventory), shrinking for four consecutive years running. That’s a market winding down its construction cycle slowly and deliberately rather than swinging from one extreme to the other.
Investment Market
Boston is the one market here where transaction volume is moving the wrong direction. TTM volume fell 9.4% YoY to $4.7B even as Q2’s $999.2M ticked up 3.7% from a year earlier.
Cap rates have sat in a tight 5.23%-5.26% band for two full years, and price per unit just set a new market record at $403,711. Record pricing paired with falling volume isn’t a repricing, it’s a standoff between buyers and sellers.
