Airbnb's monthly discount, Facebook groups and WhatsApp signs locals use, and the real costs beyond rent: a guarantor, a deposit, and what an unfurnished apartment here means.
For a month or more, Airbnb's built-in monthly discount (28+ nights) typically brings the nightly rate down by around 40% compared to booking one night at a time, and Airbnb sometimes adds its own extra savings on top for stays that length. Past a few repeat stays with a host you trust, some guests negotiate directly outside the app, though this is against Airbnb's terms and puts the host's account at real risk if reported. For anything longer than that, most residents find housing the way locals do: walking neighborhoods for handwritten 'se renta' signs and WhatsApping the number directly, and Facebook groups like Renta Roma Norte or CDMX Housing, Rooms, Apartments, Sublets, both faster and more current than real estate listing sites. Beyond rent, budget for a security deposit (one to two months, up to three without a local guarantor), and know that a fiador is close to impossible for a foreigner to arrange, so most landlords will accept a paid rental-guarantee policy instead, and that 'unfurnished' in Mexico City can mean a bare concrete shell with no stove, fridge, or light fixtures.
Past a month, monthly furnished rentals undercut nightly hotel and Airbnb rates fast, but the path to finding one looks different at every length of stay. A five-week trip, a language-school semester, and a permanent move each call for a different approach, and the costs beyond rent are easy to miss until a lease is already signed.
Airbnb lets hosts offer a weekly discount (7+ nights) and a separate monthly discount (28+ nights), and only the longer one applies, they don’t stack. The savings are real: the median nightly rate for a 7-night stay runs about 18% below booking one night at a time, and a full 30-day stay averages around 43% cheaper per night. On top of whatever discount the host sets, Airbnb sometimes adds its own additional monthly savings for stays of 28 nights or more, paid by Airbnb itself rather than deducted from the host’s payout. For relocating to CDMX rather than extending a trip, the full logistics process lives on Move to CDMX.
After a few stays with the same host, it’s common for guests to ask about booking directly the next time, skipping Airbnb’s fees on both sides. It’s worth knowing this is explicitly against Airbnb’s terms of service: hosts caught soliciting or accepting off-platform bookings risk having their listing removed or their account deactivated, and a guest who books that way loses Airbnb’s dispute resolution and guest protections entirely if anything goes wrong. It happens often between guests and hosts who already trust each other, but it’s a real risk to the host’s account and a real loss of protection for the guest, not a minor workaround.
Real estate listing sites like Vivanuncios and Trovit exist, but a large share of their listings are outdated or already rented. Two methods work better in practice. The first is walking the specific neighborhoods under consideration and looking for handwritten “se renta” (for rent) signs, then WhatsApping the number listed directly. Many landlords list this way specifically to avoid real estate agent commissions, and it’s often the fastest way to see a unit the same day. The second is Facebook groups built around this: Renta Roma Norte, Departamentos en Venta y Renta en la Colonia Roma, Renta Condesa - Cuauhtémoc - Polanco - Roma - Narvarte, and the broader Mexico City Housing, Rooms, Apartments, Sublets group all have new furnished and unfurnished listings posted constantly, often before they reach any listing site at all.
Enrolling at a Spanish-language school does more than teach the language. School administrators regularly help students find housing directly and can point toward realtors they’ve worked with and trust, and the other students around a language school are a real source of word-of-mouth leads on a neighborhood, a landlord, or a room opening up. Homestay Programs covers a few of the schools that offer this kind of support alongside their courses.
The deposit. One to two months’ rent is standard, and landlords sometimes ask for up to three months when there’s no local guarantor backing the lease.
The fiador problem. A traditional Mexican lease asks for a fiador (guarantor): a Mexican resident who owns property in the same city with no mortgage remaining on it. That’s close to impossible for most foreigners to produce. The common workaround is a paid rental-guarantee policy, a póliza jurídica, which runs roughly 25–30% of one month’s rent for basic coverage, up to about 70% of a month’s rent for a more comprehensive policy that also covers property damage and rent-payment guarantees. Landlords who won’t accept a póliza will sometimes accept a larger upfront deposit instead.
What “unfurnished” means. In Mexico City, sin muebles can mean a genuinely bare concrete shell: no stove, no refrigerator, no light fixtures (sometimes bare wires hanging from the ceiling), no water heater, no closets. Kitchen cabinets and countertops are common but not guaranteed. Buying and installing a stove and fridge from scratch is a real, easy-to-underestimate cost for a short stay. Filtering specifically for semi-amueblado (semi-furnished, which usually guarantees at least a stove and fridge) or amueblado (fully furnished) avoids the surprise entirely.
The lease itself. One year is the standard term for both furnished and unfurnished leases in Mexico City, though shorter six-month terms are increasingly available for corporate relocations, students, or anyone who wants to avoid committing for a full year up front. Agency commissions for finding a tenant are typically paid by the landlord rather than the tenant, though this varies enough that it’s worth confirming directly with any realtor before assuming either way.
