Metz vs Seixal

Seixal is the pragmatic pick for anyone who wants Lisbon access without Lisbon rent: a 1-bedroom outside the center runs $645/mo, the overall cost of living index sits at 48/100, and LIS is 6 km away. The catch is that a local average net salary of $1,570/mo barely clears the mid-range tier of $1,242/mo, so remote workers and retirees on outside income get far more out of this town than people hunting local jobs. The expat scene is small and English is common mainly in tourist areas, so expect to learn some Portuguese if you want a social life beyond Corroios and Amora. With a safety index of 85/100 and healthcare rated excellent, it is a solid, unglamorous base rather than a destination in its own right.

A one-bedroom in central Lisbon runs about $1,040/month, roughly a third of comparable Boston or DC rents. Combined with $776 in monthly living costs, a couple can live well under $2,500/month total, and the D7 visa only requires $1,031 income to qualify. The catch: Portuguese progressive tax hits 48% (top bracket), so this works best for retirees on fixed foreign income, not high earners staying tax resident.
