Field notes
Post-2022 tech layoffs softened rents 10–15% from peak, but the AI boom has them climbing again — Hayes Valley and the Mission are back to bidding wars. Coworking is bifurcated: the SoMa corporate stack vs the founder-y spaces along Valencia. California state tax (13.3% top marginal) plus aggressive residency audits make SF the worst US city to accidentally become a tax resident in — six-month stays trigger the franchise board's attention.

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.
