The Expat Vibe
🇦🇷 Buenos Aires
South America's most European city — tango, steak, psychotherapy culture, and a vibrant, intellectual energy powered by a deeply affordable (if economically chaotic) peso.
🇲🇽 Mexico City
A massive, cosmopolitan culinary powerhouse and the undisputed remote work capital of North America — bursting with culture, history, and absurdly affordable luxury.
Housing & Rentals
🇦🇷 Buenos Aires
Argentina's currency crisis makes USD go extremely far — but also creates chaos. Most landlords demand payment in USD cash (blue dollar rate). Short-term rentals are common. Formal leases require a 'garantia propietaria' (property guarantee) which is nearly impossible for foreigners — use Airbnb or short-term contracts.
Top neighborhoods: Palermo (Soho/Hollywood), Recoleta, San Telmo, Belgrano
🇲🇽 Mexico City
Foreigners usually lack a 'Fiador' (local property-owning guarantor), so a 'Poliza Juridica' (legal insurance policy) is the standard workaround to secure a lease. Furnished apartments in Roma/Condesa run $800-1,500 USD/mo. Airbnb dominates short-term.
Top neighborhoods: Roma Norte, Condesa, Polanco, Coyoacan, Juarez
Getting Around
🇦🇷 Buenos Aires
Subte (metro) is ancient but functional. Colectivos (buses) cover the entire city and are incredibly cheap. SUBE card is mandatory for all transit. Taxis/Uber are extremely affordable. The city is flat and bikeable.
🇲🇽 Mexico City
The Metro is one of the busiest in the world — very cheap (5 pesos) but extremely crowded at peak hours. Most expats rely on Uber/Didi and walking within Roma-Condesa-Polanco bubbles. Ecobici bike-share is excellent in flat central areas.
Cost of Living Details
🇦🇷 Buenos Aires
One of the cheapest major cities in the world for USD earners (due to favorable exchange rates). A couple can live excellently on $1,500-2,500/mo. A premium steak dinner with wine costs $15-25. Cafe culture is central — cortados cost $1-2.
🇲🇽 Mexico City
Extraordinarily affordable by global standards. A couple can live very well on $2,000-3,000/mo including rent. Street tacos cost $0.50-1.50, a sit-down meal at a good restaurant $8-15. Supermarkets are cheap. The biggest expense is rent in trendy neighborhoods.
Climate & Weather
🇦🇷 Buenos Aires
Humid subtropical. Hot summers (Dec-Feb, 30-38°C) and mild winters (Jun-Aug, 8-16°C). The 'sudestada' (southeast wind) brings extended gray, rainy periods. Spring and autumn are ideal.
🇲🇽 Mexico City
Eternal spring at 2,240m elevation — daily highs of 20-27°C year-round. Rainy season (June-October) brings dramatic afternoon thunderstorms that clear within hours. Never humid, rarely cold. Occasional air quality alerts in winter.
Food & Dining
🇦🇷 Buenos Aires
Steak at Don Julio (book weeks ahead), pizza at Guerrin or El Cuartito, empanadas at El Sanjuanino. Sunday market at San Telmo for choripan (chorizo sandwich). Ice cream (helado) culture rivals Italy — Rapanui and Cadore are top picks. Cafe Tortoni for the classic Buenos Aires coffee experience.
🇲🇽 Mexico City
The world's greatest street food city. Tacos al pastor at El Vilsito (a mechanic shop by day), churros at El Moro, tlacoyos at Mercado de Coyoacan, pozole at Fonda Margarita. Fine dining: Pujol and Quintonil are world-ranked. Mercado Roma for upscale food hall experience.
Insider Tips
🇦🇷 Buenos Aires
The official exchange rate and the 'blue dollar' (parallel/informal rate) differ dramatically — sometimes 2x. Always exchange USD at 'cuevas' (informal exchange houses) in the financial district or use Western Union for the best rate. Never exchange at a bank or airport. This single hack effectively halves your cost of living.
🇲🇽 Mexico City
Get a Mexican phone number immediately (Telcel prepaid, $5) — it unlocks local Uber pricing, MercadoLibre delivery, and makes apartment hunting dramatically easier. Also, the 180-day tourist visa is generous but does NOT allow you to work legally — the digital nomad visa (temporary resident) is worth the paperwork if staying 6+ months.
