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.

About Lima
Lima is the best value big city in South America for expats who can tolerate gray skies and a language barrier, with a cost of living index of 36/100 and a one-bedroom outside the center at $337/mo. The catch is that local salaries average $651/mo, so the comfortable tier at $1,184/mo puts you in a different economy than most Limeños, and the safety index of 45/100 plus an air quality index of 85 means Miraflores, Barranco, and San Isidro are worth their premium. Digital nomads and early retirees will thrive on the 76/100 expat score and the Rentista visa's $1,000/mo income floor, but retirees should note the 59/100 retiree score and limited English proficiency. Come for the $4 restaurant meals and 60 Mbps internet, stay if you can handle the Garúa.
About Peru
A 1BR in central Lima runs $521.77/mo, less than a parking spot in Manhattan, and the Rentista Visa requires $1,000/mo income to qualify. That math works for retirees on fixed Social Security checks. But the Safety Index sits at 32.9 so the savings come with real security tradeoffs. Worth it only if you vet neighborhoods hard and skip the flash.
