Deliveries slow as fundamentals improve for the Boston multifamily market

Greater Boston multifamily market overview

The Boston multifamily market strengthened in the second quarter as the local job market returned to annual growth for the first time in two years. That stronger footing showed up quickly in leasing activity, with tenants absorbing apartments well ahead of the pace that developers completed them, tightening vacancy and giving landlords room to push rents higher. The improvement was broad-based, with conditions strengthening across the quality spectrum. Meanwhile, the supply pipeline is thinning, completions have slowed considerably, and developers have pulled back on permitting well below typical levels. That said, the improvement wasn't universal. In Brookline, Newton, and Watertown, ongoing construction met softer demand than elsewhere, causing vacancy to move in the opposite direction of the broader market. The trend suggests that even the region’s most land-constrained suburbs are not immune to the short-term effects of new supply.

The Boston multifamily investment market cooled from an unusually front-loaded start to the year. Two of the year's largest trades, combining for more than $350 million, closed in the first quarter and accounted for more than one-third of first-half dollar volume. Excluding those transactions, deal size was far more consistent, with the remaining first quarter sales averaging about $23 million compared with roughly $28 million in the second quarter. What has shifted is the profile of what's trading. Buyers have gravitated toward smaller, older properties outside the urban core, a trend underscored by the absence of Class A property transactions in the second quarter. That divide extends to pricing as well, with recently built assets trading at meaningfully tighter cap rates than older stock, consistent with the broader shift toward value-add product.

Looking ahead for Boston:

Operating fundamentals in Boston should continue improving through the second half of the year, though at a more measured pace than the second quarter's numbers suggest. Employment is on pace for its first annual increase since 2023, aided by recently announced expansions like Boston Dynamics' Waltham project, though hiring remains below the longer-term trend. Development activity is set to slow further, as two years of modest permitting leave fewer projects ready to break ground, with full-year completions on track to fall well short of the historical norm. That pullback in supply arrives alongside typical seasonal moderation in fundamentals, with vacancy and rents expected to give back some of this quarter's gains by year end. One source of uncertainty has diminished. The state’s high court removed the proposed rent control measure from the November ballot in June, though legislative efforts to advance rent stabilization remain ongoing.

Investment activity in Boston is likely to remain below last year’s levels through the remainder of 2026, absent a return of the large trades that lifted activity during the first quarter. Barring that, the shift toward smaller, older assets in outer submarkets should persist, while overall average cap rates are likely to hold in their current range or drift modestly higher, given the pricing gap that exists between newer and older product. One submarket worth watching is Metro West, already the year's most active by deal count: Boston Dynamics' planned expansion in Waltham could draw additional investor attention to the corridor in the coming quarters. A pickup in permitting or a return of larger transactions would be the clearest signal of improving confidence and a broader recovery in investment momentum.
