Field notes
Cascais sits 30 minutes from Lisbon by train but feels half a world quieter. Estoril and Monte Estoril have the international-school + family-nomad concentration; the old town is where the cafés and surf-adjacent crowd cluster. Rents climbed in lockstep with Lisbon since 2023 — expect roughly 70–80% of Lisbon prices, not 50%.

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.
