About these cities
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.

About Greystones
Greystones is a small coastal town that prices like a Dublin suburb, and the rent gap tells the story: $2,128/mo for a one-bedroom in the center versus $1,008/mo outside it, so living car-free near the DART line costs you dearly. With an average monthly net salary of $3,359/mo and a single person spending $1,050/mo excluding rent, the numbers only work for remote workers earning elsewhere or dual-income households. The safety index of 85/100, air quality index of 35, and excellent healthcare are real draws, but a small expat community and a $4,350/mo income floor for Ireland Stamp 0 mean this is a quiet, expensive choice rather than an easy landing.
About Ireland
A city center 1BR at $1,776.90 a month rivals rents in Boston or DC, with no digital nomad visa available. Retirees need USD 4,350/mo proof of income, a real barrier at 20-40% progressive tax plus PRSI and USC. English fluency and a clear citizenship path help, but the math only works if your retirement income clears that bar comfortably.
