Multifamily Investment in Boston
Boston multifamily stays hot despite interest rate pressure. Cap rates compressed to 4.2%-5.1% for quality product, driven by tech job growth and chronic housing shortage. Supply pipeline can't keep up with demand - we're seeing 95%+ occupancy across most submarkets. Cambridge and Somerville lead pricing at $800+ per unit per month, while emerging areas like Assembly Row and Seaport command premium rents. Student housing around universities trades differently - expect 6-8% caps but higher management intensity.
