median declared expensas for a 1-bedroom apartment, across 17,710 active long-term listings that publish the number

Expensas add around 21% to asking rent, at every size. The problem is not just how much they are: 67% of listings simply do not publish them. Here is what the ones that do declare, neighborhood by neighborhood and size by size.

Only expensas declared in the listing text; our estimates are excluded from these medians. Long-term contracts, no temporarios. Amounts converted to dollars.

67% do not publish them

Two out of three long-term listings do not declare expensas. Before signing, always ask for the apartment's latest expensas statement, and ask whether extraordinary installments are running: a building works project can add large amounts for months. On Unitrank, when the listing does not declare, we estimate from neighboring buildings and listings and label it as an estimate.

Per-neighborhood median of listings with declared expensas, 1-bedroom, long-term contracts. The percentage is the median of expensas over asking rent, listing by listing. A dash means insufficient sample.

What expensas are

The monthly cost of running the building: staff, cleaning, elevators, insurance and central services. Paid every month on top of rent. Ordinary expensas are by convention the tenant's; extraordinary ones, major works, are negotiated in the contract and by convention fall to the owner. No rent number is complete without them: that is why every Unitrank total includes them.

Search with expensas already added

Every Unitrank search ranks by total cost with expensas inside, declared or estimated and labeled. No listing surprises you later with the number it did not publish.

FAQ
What are expensas?+
The monthly cost of running the building: staff salaries and charges, cleaning and maintenance of common areas, elevators, insurance and central services. When renting, you pay them every month on top of the rent. Ordinary expensas are by convention the tenant's; extraordinary ones, major building works, are negotiated in the contract and by convention fall to the owner.
How much are average expensas in Buenos Aires?+
Across active long-term listings that declare them, the median is US$ 108 per month for a 1-bedroom, and around 21% of asking rent at every size: US$ 92 for a studio, US$ 155 for a 2-bedroom, US$ 259 for 3 or more. Building-administrator surveys publish higher per-building averages; they measure something else: their whole managed portfolio, not what active rental listings declare.
Why do so many listings not publish expensas?+
67% of long-term listings do not declare them. Sometimes carelessness, sometimes because the number scares people off. Before signing, always ask for the apartment's latest expensas statement, and ask whether extraordinary installments are running: a building works project can add large amounts for months.
What drives expensas up?+
The largest component is building staff, then the upkeep of services: a pool, 24-hour security, a gym and parking all raise the monthly bill. A building with no doorman and no amenities can cost a fraction of a full-service tower in the same neighborhood.
How does Unitrank handle expensas?+
Every search ranks by total cost, and expensas are always inside it: when the listing declares them we use that number as stated; when it does not, we estimate from neighboring buildings and listings and label it as an estimate on the listing page. The numbers on this page use declared expensas only.

The number missing from the listings

Public expensas averages come from building-administrator surveys: their whole managed portfolio, one number for the whole city. We publish this cut because a renter needs a different one: what active listings declare, in their neighborhood and their size. It comes from each listing's own text and updates weekly.
