About these cities
About Mainz
Mainz is a quietly excellent pick for expats who want strong safety and healthcare without big-city rent, with a 1-bedroom in the center at $916/mo and a cost of living index of 70/100 against a $3,221/mo average net salary. The catch is the language: English proficiency is limited, so you will need German to get past surface-level living. At 223 thousand people it is small enough to feel manageable, and the 85/100 safety index and 15/100 crime index back that up. Come for the livability and the 7 km hop to WIE, stay only if you are ready to learn the language.
About Germany
Germany suits retirees with steady income and no rush toward citizenship shortcuts. A EUR 1,200/mo retirement visa threshold is trivial to clear, and $942.63 rent for a city-center 1BR beats most Western Europe. Healthcare scores 71.9 with English-speaking doctors widely available. The catch: progressive tax up to 45% and no digital nomad visa is currently offered.

About Oeiras
Oeiras is a solid pick for expats who want Lisbon's airport 6 km away without Lisbon's crowds, and an overall expat score of 86/100 backs that up. The catch is the money: city centre one-bedroom rent runs $1,458/mo against an average monthly net salary of $1,477/mo, so you need remote income or savings, not a local job. English proficiency is limited and the expat community size is none, which means learning Portuguese is not optional here. Come for the Mediterranean climate and the D7 Passive Income Visa at $1,031/mo minimum, not for a ready-made social scene.
About Portugal
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.
