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.
- Colombia: Prices in Colombian pesos, no currency conversion.
- 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.
