The Allston/Brighton submarket remains one of Boston’s strongest performers, with solid absorption and stable vacancy rates near metro averages. Roughly 1,000 units are under construction—about 9% of total inventory—yet demand is keeping pace. Rents grew ~2% year-over-year, outperforming the national average and signaling steady renter appetite. CoStar forecasts continued stability, making this a resilient market for new multifamily investment like 119 Braintree Street.
