Boston multifamily transaction activity accelerates

Q1 2026

Greater Boston multifamily market overview

A slowing pace of new multifamily deliveries lessened supply-side pressures in the first quarter, allowing for a modest rebound in area rents. Projects totaling roughly 1,000 units came online during the first quarter, after more than 5,000 units completed in the second half of 2025. Fewer units are coming online and the development pipeline is now composed of a meaningfully different product mix than in the prior cycle. After developers delivered a few dozen luxury high-rise properties during the past decade, nearly 40% of the units currently underway are Class B complexes. Class B vacancy has risen roughly 90 basis points over the past year to 5.6%, while rents in that segment finished the first quarter at approximately $3,000 per month. The continued delivery of Class B product could weigh on both rent growth and occupancy in that segment through the remainder of the year.

The Boston multifamily investment market opened 2026 with its most active first quarter in recent years. Transaction totals during the first quarter ran more than 50% ahead of levels from the same period last year. The quarter was defined by a clear bifurcation in activity. Two significant deals, a $218 million acquisition in Cambridge and a $137 million purchase in Salem, New Hampshire, combined to account for nearly 60% of total first-quarter dollar volume, while Class C assets represented nearly half of all trades. Across all transactions, activity was concentrated along the Route 1 North and Metro West corridors, which together accounted for more than one third of all first-quarter closings.

Looking ahead:

The fundamental backdrop for Boston multifamily is gradually improving. Deliveries are forecast to decline nearly 25% in 2026, the construction pipeline continues to thin, and capital is rotating into the sector. The recently announced headquarters relocations by LEGO and Hasbro to the Boston region are expected to add jobs and provide a tangible offset to the employment softening that has weighed on demand through the early part of the year. Against this improving backdrop, however, one variable threatens to overshadow near-term fundamentals. A statewide ballot initiative scheduled for November 2026 proposes capping annual rent increases at the lower of CPI or 5%, though newly constructed buildings would be exempt from the cap for 10 years from the date of completion. While that carveout could drive renewed investor appetite for newly delivered product, the broader outcome of the initiative may prove more consequential to long-term return assumptions than any near-term shift in vacancy or rent growth.

Multifamily transactions are likely to remain the leading destination for capital in Boston, continuing a trend in which the asset class has accounted for more than 40% of all commercial real estate activity in the region for three consecutive years. With first-quarter activity already running well ahead of last year, full-year transaction totals are on pace to surpass 2025 levels, provided market conditions remain stable. Pricing has held firm through the rate cycle, and suburban markets along the Route 1 corridor and established nodes south of the city continue to attract consistent buyer interest. On the urban side, the Hasbro headquarters relocation to the Seaport District is a development worth monitoring. The Seaport District has recorded limited new apartment supply relative to peer submarkets, and a meaningful influx of white-collar employment could generate value-add opportunities in a corridor that has lagged on the investment side in recent years.
