Field notes
South End, Cambridge (Inman/Central), Somerville, and Jamaica Plain are the nomad-dense neighborhoods; the universities (Harvard, MIT, BU, Northeastern) shape the academic-year rhythm — September lease turnover is a known choke point. Massachusetts has the 'Millionaires Tax' — 4% surtax on income over ~$1M on top of the 5% flat — and aggressive residency rules. Winter is real; the T is unreliable enough to be a regular complaint.

Editorial estimates. Not financial advice. The 4% rule is a planning anchor, not a guarantee — sequence-of-returns risk and tax-jurisdiction friction (US-LLC / FEIE / state residency) can move the real number meaningfully. See our expat tax directory for the cross-border side of the math.
