Zonaprop Scraper - Argentine Property Listing Data

What we extract from a Zonaprop listing

Each search page and listing page carries a structured object behind the rendered markup. We read that object rather than guessing at rendered text, so fields arrive typed and the native Spanish labels stay attached to them. A standard extract includes:

• precio (price) with its own currency marker - every price is stored with an explicit currency of USD or $, never as a bare number.
• operacion - Alquiler or Venta, taken from the operation object rather than inferred from the URL.
• expensas (monthly building charges) as a separate amount carrying its own currency, independent of the rent or the asking price.
• ambientes (rooms in the Argentine sense) and dormitorios (bedrooms) as two distinct integers.
• superficie total and superficie cubierta (total and covered floor area), delivered with the m2 unit the site attaches to them.
• baños (bathrooms), cocheras (parking spaces) and antigüedad (building age in years).
• Descriptive attributes such as Disposición (frente or contrafrente), Orientación, Amoblado, Luminoso and Apto crédito.
• Location as a hierarchy - país, ciudad or provincia, then barrio or partido - each level with its own identifier, plus the street address and the visibility flag that states whether the exact address is published.
• Publisher: the inmobiliaria name and its profile identifier, or the marker that a listing is owner-published.
• Listing identifier, canonical URL, headline, free-text description, photo URLs, and the date and time of our own read.

Fields a listing does not carry come back empty rather than filled with a guess. Argentine stock is inconsistent about antigüedad and about superficie total in particular, and a pipeline that quietly substitutes zero for a missing value will skew every later aggregate you build on it.

What Zonaprop scraping has to get right

Expensas are the monthly building charges an occupant pays on top of rent, covering shared services, staff and upkeep. On Zonaprop they are a field of their own, not a component of the rent. In dense Buenos Aires stock they are large enough that ranking rentals by advertised rent alone reorders the list wrongly. An honest rental comparison adds expensas to rent first, which is only possible when both figures keep their own currency and observation date.

Ambientes is the Argentine room count and it is not a bedroom count. It counts habitable rooms including the main living room, so a property advertised as 4 ambientes has fewer dormitorios. In an archived capture of the Palermo rental search dated 23 July 2026, one listing headlined 2 Dorm. carried a site-generated title of 4 Ambientes. Mapping ambientes onto a bedrooms column corrupts every comparison against a market that counts bedrooms directly, so we deliver both under their native names.

Geography splits in two. Inside the Capital Federal a listing resolves to a barrio such as Palermo, Belgrano or Caballito. Outside it, in the surrounding province, it resolves to a partido such as Vicente López, San Isidro or Tigre, commonly grouped under a wider zone label. Both appear in the search slug and in the location tree, which nests país, ciudad and barrio with a stable identifier at each level. We keep the identifiers, not only the names, because place names repeat across provinces.
