About Mexico City
Mexico City delivers a lot of city for the money, with a mid-range single lifestyle running about $1,181/mo including rent, though the average local salary of $995/mo tells you who really benefits. The expat scene is large and active, and neighborhoods like Roma Norte and Condesa are packed with digital nomads, but the safety index of 34/100 and an air quality index of 148 are genuine drawbacks you can't ignore. You'll need to show $2,600/mo in income for the digital nomad visa or $3,738/mo for the temporary resident visa, which is steep compared to local wages. If you can handle the altitude and the smog, this is a solid, affordable base for remote work, but it's not the low-cost paradise some make it out to be.
About Mexico
Safety-sensitive retirees should pause: a 46.6 safety index and a significant safety index gap may signal real risk. But budget-conscious Americans willing to navigate that tradeoff get low rent (a one-bedroom city-center apartment averages $659.65\/mo), a large expat network, and an easy $3,738/mo income visa path to permanent residency.

About Buenos Aires
Buenos Aires is a genuinely affordable big-city play, with a cost of living index of 51/100 and a one-bedroom outside the centre at $510/mo, but the local average net salary of $938/mo means your budget has to come from elsewhere. The digital nomad and expat scores of 73/100 are earned, not gifted, and the large, active expat community in Palermo, Recoleta and Belgrano makes landing easy. The catch is a safety index of 45/100 and a crime index of 55/100, so pick your neighborhood and your hours with real care. Come for the low rent and the food, stay if you can tolerate the humid subtropical summers and damp winters.
About Argentina
Rentista visa access at $1,500/mo income against 35.7 COL versus NYC makes Argentina a math play for retirees on fixed dollar income, not a lifestyle upgrade. Low crime scores (36.6 safety, 52.4 crime index) mean this suits someone prioritizing cash flow over personal security, accepting medium-risk tradeoffs. Bad fit: anyone needing English-first daily life or spooked by 35% income tax and political instability undermining long-term peso planning.
