About Kopavogur
Kopavogur is a small, safe, and expensive suburb of Reykjavik that works best for remote workers and expats who value English proficiency and a large, active community over affordability. A single adult needs roughly $3,400/mo to $5,500/mo including rent, while a local net salary of $5,312/mo leaves little room for savings, which explains the middling FIRE score of 58/100. The payoff is excellent healthcare, a safety index of 85/100, and a 3 km hop to RKV, all wrapped in a town of 40 thousand people. If you can stomach the rent, Hamraborg and the rest of Kopavogur deliver a comfortable, well-connected base without Reykjavik's full price tag.
About Iceland
Iceland works for high earners with remote income and no need for a large expat scene, not budget retirees. Rent alone runs $2,333/mo in the city center, before the ~46% top income tax bracket takes its cut. No retirement visa exists, but the digital nomad visa requires ISK 1,000,000/mo, roughly $7,200 (depending on exchange rate), and leads nowhere toward permanent residency.

About Boulogne-Billancourt
Boulogne-Billancourt is a pricey Parisian suburb where a one-bedroom in the center runs $1,650/mo and a single person needs $2,900/mo for a budget lifestyle. The safety index of 85/100 and excellent healthcare are strong draws, but the climate is relentlessly gray and rainy. Expats will find a large, active community and decent English in tourist areas, though the digital nomad visa demands a steep $5,000/mo minimum income. It works best for well-funded professionals who want proximity to Paris without the full chaos.
About France
Retirees with steady income and no interest in remote-work loopholes fit best, since France offers both a retirement visa and a digital nomad option. A retirement income of USD 1,500/mo clears the bar easily for most Social Security checks. Progressive tax up to 45% and a complex citizenship path mean this is a long-term lease on French life, not an ownership deal.
