Finding a decent short-term apartment in a South American city without paying through the nose on platforms like Airbnb is one of those travel challenges that feels harder than it should be. You know the right options exist — locals subletting furnished apartments, expats heading home for a month, digital nomads passing the lease — but tracking them down requires knowing where to actually look. The good news is that a parallel rental ecosystem operates in most major cities, and it runs almost entirely through Facebook groups and physical bulletin boards. Once you know how to use them, the whole process gets a lot easier.
Join the Right Facebook Groups Before You Arrive
The first move is to find and join the relevant expat and housing groups at least two to three weeks before your arrival. Groups like "Expats in Buenos Aires," "Bogotá Expats," and "Gringos in Lima" have tens of thousands of members and active housing threads running daily. Search Facebook for your destination city combined with terms like "expats," "housing," "sublet," or "apartments." Join three to five groups per city — there's usually overlap, but each one surfaces different listings. Read the group rules before posting, since many have dedicated housing days or pinned threads specifically for accommodation requests.
Write a Clear, Specific Housing Request Post
Once you're in the groups, posting a well-written request matters more than most people expect. Landlords and subletters are choosing who to respond to, so a vague post gets ignored while a specific one gets replies. Mention your dates, your budget range, how many people are staying, and something human about yourself — that you're a remote worker, that you're quiet, that you've rented long-term in other cities before. Posts that build basic trust tend to get better leads. Keep it under 150 words and post during local morning hours when engagement is highest.
Use Bulletin Boards in Coworking Spaces and Cafés
Physical bulletin boards in coworking spaces are genuinely useful and often overlooked. In Medellín, spots like Selina and local coworking hubs in El Poblado maintain active boards where both locals and expats post housing offers. In Santiago, cafés around Barrio Italia and Lastarria often have flyers from people looking to sublet furnished rooms or entire apartments for a month or two. These listings rarely make it online, which means less competition and more room to negotiate directly. Walk through these neighborhoods in your first day or two and photograph every housing notice you see.
Check Group Albums and Pinned Posts First
Before posting your own request, dig into the group's existing content. Many expat Facebook groups maintain photo albums or pinned posts that aggregate housing listings, trusted landlord recommendations, and neighborhood guides. These are updated regularly and can save hours of searching. In groups focused on cities like São Paulo or Lima, you'll often find that members have pinned spreadsheets or running document links with vetted short-term rentals that never appear on major booking platforms. It takes five minutes to look through these, and the leads are often better quality than anything you'd find by posting cold.
Reach Out Directly to Long-Term Group Members
Some of the best sublet opportunities come not from open posts but from direct messages to people who've been active in the group for a while. Someone who's been living in Palermo Soho for two years and posts regularly probably knows a neighbor subletting their place, or might be leaving for a few weeks themselves. A short, polite message explaining your situation and asking if they know of anything available converts surprisingly often. It's the digital equivalent of asking a local — and in expat communities, people are generally happy to help newcomers find their footing.
Verify Listings With a Video Call or Photos Request
Short-term sublet scams do exist in popular cities, particularly in areas with high expat traffic. Before sending any deposit, ask for a video call walkthrough of the apartment or a live video showing the view from the window and the building entrance. Cross-reference the address on Google Street View, and check that the person posting matches the name on any rental agreement. Legitimate subletters understand these requests and expect them. Anyone who pushes back hard on basic verification is a flag worth taking seriously. This step takes twenty minutes and protects you from the worst outcomes.
Time Your Search Around Local Rhythms
Sublet availability in South American cities follows patterns tied to local academic calendars, holiday seasons, and expat turnover cycles. In Buenos Aires, January and February see a surge in short-term listings as locals travel to the coast and expats head home for northern hemisphere summers. In Bogotá, the period just after Semana Santa tends to open up furnished apartment options as short-term contracts end. Posting your housing request during these natural turnover windows increases your chances of finding something furnished, flexible, and reasonably priced. Getting the timing right is half the work.
Negotiate Directly and Confirm Everything in Writing
One of the genuine advantages of finding a sublet through community channels is the room to negotiate. Unlike platform bookings with fixed rates and service fees, a direct arrangement with a person gives you flexibility on price, move-in dates, what's included, and payment method. Have the conversation in writing — even if it starts on WhatsApp — and document the agreed terms before transferring anything. A simple message outlining dates, monthly rate, deposit amount, and what utilities are covered is enough. It protects both sides and eliminates the kind of misunderstandings that ruin what should be a straightforward arrangement.
The way expats and long-term travelers find housing in South American cities is shifting as these online communities grow more organized and more trusted. Groups are becoming more structured, with dedicated moderators, vetted listing formats, and even internal reviews of landlords and subletters. The bulletin board culture in coworking spaces is evolving too, with some spaces in cities like Medellín now maintaining digital versions of their boards accessible to remote members. The fundamentals — real people, direct communication, community trust — stay the same. Getting comfortable using these channels now means you'll always have a reliable path to affordable, well-located housing wherever you land next.
