About Caernarfon
Caernarfon is a small town of 10 thousand people where a one-bedroom outside the center runs $420/mo and the average net salary is $3,535/mo, so a single adult can live comfortably on the $2,100/mo mid-range tier and still bank serious money toward FIRE, which explains the 84/100 FIRE score. The catch is that this is not a big-city expat scene: the community is small, the airport is LPL at 11 km, and you come here for the castle, the coast, and the quiet rather than for career networking or nightlife. If you want a low-cost, safe, walkable base with good healthcare and 70 Mbps internet, Caernarfon delivers; if you need a large international crowd, look elsewhere.
About United Kingdom
No retirement visa exists, and a difficult residency and citizenship path rules out anyone seeking a straightforward move. Rent near $1,344/mo plus 20% basic, 40% higher, 45% additional income tax bites hard. This fits Americans with UK ancestry, employer transfers, or high earners who value large expat networks and English-language ease over affordability.

About Lisbon
Lisbon is the rare European capital where a single adult can live on a budget tier of $1,137/mo and still walk past tiled facades to a $3 cappuccino. The catch is the salary math: local net pay averages $1,572/mo while a city-center one-bedroom runs $1,596/mo, so remote workers and D7 retirees win here far more than job seekers do. With a cost of living index of 54/100, an expat score of 86/100, and excellent healthcare, the tradeoff is real but the value is undeniable. Come for the light and the $45/mo transport pass, stay if your income does not depend on Lisbon.
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.
