Rio de Mouro vs Nyons

Rio de Mouro is a quiet commuter town of 47 thousand where your money goes remarkably far: a 1-bedroom outside the center runs $840/mo, utilities $108/mo, and a monthly transport pass $45/mo, all against a cost of living index of 49/100. The catch is that local net salaries average $868/mo, so unless you arrive with remote work or passive income, the math gets ugly fast. It is 8 km from LIS and scores 80/100 for expats and FIRE, but with limited English and no expat community, you had better come for the cheap rent and Lisbon access, not for the social scene.

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.
