Methodology
- Source: night events of the Aptology database (aptologia.com) of 18 October 2026: current housing ads in real estate portals of 13 countries, collected by Aptology and seen online between 11 and 18 October 2026. Court: 18 October of 2026.
- Debugging: exact duplicates (same city, area, type, price, currency, area, rooms and bathrooms) and prices outside the percentile 1 - 99 of each country, operation, currency and type are removed; the price per m² uses only ads with declared area between 12 and 2,000 m² and is also cut to P1-P99.
- What is measured: prices ordered (published), not closing prices. For rent, monthly rent without HOA fee, common expenses or condo.
- Minimum sample: each published figure is based on at least 30 ads; cells with less are omitted.
- Coins: never mix different coin ads without converting them. Conversión a dólares con la tasa de mercado de ExchangeRate-API (open.er-api.com, actualización del 18 Oct 2026): 1 USD = 3,182.80 COP, 1 USD = 18.47 M.N, 1 USD = 5.09 BRL, 1 USD = 3.44 PEN, 1 USD = 982.44 CLP, 1 USD = 1,514.57 ARS, 1 USD = 40.20 UYU, 1 USD = 5,705.37 PYG, 1 USD = 61.27 DOP, 1 USD = 0.89 EUR, 1 USD = 11.72 BOB; la UF chilena a 41,178.64 CLP (mindicador,cl. 18-oct-2026). The ads published in dollars are used as they are.
- Coins: In each city and operation only the majority currency of the ads is used (the ads in another currency are excluded) and the median is converted to dollars at the rate mentioned; no different currency ads are ever averaged.
- Cordura: only published if the median grows in size.
- Limitations: The coverage depends on the portals that travel Aptology in each country and is greater in large cities and in the medium-high and high segments; the area is the one that declares the announcement, unverified; the area names come from the portals.
- Privacy: only aggregates are published; no personal data, link to ads or name of advertiser is published.
