The Week in Three Parts
How We Got Here
Boston never overbuilt: permitting has run well below typical levels and deliveries slowed through 2025 to 2026, keeping vacancy under 5% [144][159].
Nationally, construction fell to 3.5% of inventory, the lowest since 2013 [28].
Agency loan rates bottomed near 5.56% in early June [3] before the 10-year Treasury climbed from about 4.2% to 4.68% [1][14].
The Fed committee held rates at 3.50 to 3.75% on Jul 29, but three members voted to raise them [17][18].
Boston ranked eighth nationally in 2025 transactions: $3.2 billion across 43 properties at $346,859 per unit, the highest price per unit on the list [121].
Where We Are Now
Vacancy fell to 4.9% in Q2; asking rents $2,999, up 1.1% year over year, with the strongest quarterly growth since early 2023 [144][159].
Year-to-date absorption of 3,667 units is running ahead of 2,451 delivered [144].
Pricing: cap rates expanded modestly to 5.2%, with newer assets well inside that [144].
Inflation is still above target: CPI 3.4% in July, PCE 3.7% in June [36][37]. SOFR is 3.65% [35].
Pricing gap: 5.2% vs. agency 5-year debt at 6.20% [4], negative leverage of about 100 basis points.
The rent-control threat is off the table for now: the Supreme Judicial Court blocked the 2026 ballot initiative in June, so the statewide ban stands [160].
Where We're Headed
Rates: futures markets price two quarter-point increases (Sep 16 and Dec) [18]. If they happen, agency fixed rates extrapolate to roughly 6.5 to 6.7% by year-end [1][4].
Supply: about 13,300 units underway, 4.4% of inventory, but completions and permitting are slowing, so the pipeline thins from here [144].
Massachusetts employment was flat to negative in 2025 (-0.4% year over year in Q1 2026) and GDP growth is projected at 0.8 to 1.3% [161]; metro population growth slowed to 11,991 people, the weakest post-pandemic year [162].
The AvalonBay and Equity Residential merger will force the sale of two downtown towers (1 and 10 Emerson Place) under an Aug 19 settlement with the Attorney General [163].
Net: Boston is a low-supply, high-price market with a soft economy. Affordability keeps renters renting; the risk is jobs, not supply.
What It Means for Boston
The rate direction has flipped. Three Fed votes to raise rates and a 10-year Treasury at 4.68% mean the "wait for cuts" plan is over for 2026. Owners with loans maturing in 2026 or 2027 should model a refinance at 6.25 to 6.75% [1][17][18].
Highest price per unit on the list. $346,859 in 2025 sales [121]; cap rates 5.2% against 6.20% debt is about 100 basis points of negative leverage [144][4].
Fundamentals are firm. Vacancy 4.9%, absorption 50% ahead of deliveries, strongest quarterly rent growth since 2023 [144][159].
Rent control is deferred, not dead. The SJC kept it off the 2026 ballot [160]; expect it back in 2028.
The economy is the soft spot. Statewide employment down 0.4% year over year and the slowest population growth since the pandemic [161][162].
Boston Multifamily
Boston is a low-supply, high-price market. Vacancy dipped to 4.9% in Q2, absorption is running 50% ahead of deliveries, and rents posted their strongest quarter since early 2023. Cap rates have drifted up to 5.2%. The soft spots are jobs and population, both flat to slightly negative, and a rent-control fight that has been deferred rather than settled.

Agency lending (Fannie Mae and Freddie Mac) remains the workhorse: a combined $176 billion cap for 2026, half of which must go to affordable housing. Low-leverage agency loans price in the mid-to-high 5s as of Aug 24; higher-leverage quotes are in the low 6s. Bank bridge money runs SOFR plus 225 to 325 basis points, debt funds SOFR plus 300 to 450.

Massachusetts is trailing the nation. Employment was unchanged year over year in late 2025 and down 0.4% in the first quarter of 2026, and MassBenchmarks projects GDP growth of 0.8 to 1.3%. The Boston metro added only 11,991 residents in 2025, its slowest post-pandemic year. The rent-control ballot question was blocked in June; the statewide ban stands.

National Rates and the Fed
The Fed held at 3.50 to 3.75% in July with an unusual three-member vote in favor of raising. Markets are now pricing two quarter-point increases, September and December. The 10-year Treasury finished Aug 14 at 4.68%.

10-Year Treasury vs. 30-Year Mortgage Rate, 1980 to today
Why apartments rent: the mortgage rate sets the cost of buying a house, and the gap between it and the Treasury is the part of that cost the market has added since 2022. Monthly averages, percent. Lower panel: mortgage rate minus Treasury, in percentage points. Hover for any month.

Global Backdrop
Global bond yields moved higher this month as traders scaled back expectations for 2026 rate cuts. Energy prices are elevated on Strait of Hormuz supply risk, which adds to inflation.
