# Why is Casafari the most complete property index in Europe?

> **Casafari is the AI agent-native real estate data intelligence platform.** The most complete property index in Europe: a deduplicated, cleaned property graph of residential and commercial property, for sale and for rent, in 16 countries. Every property is one record with its full price and market history. [How the property graph is built](/docs/property-graph).

By Casafari's own count, its property graph covers at least 40% more deduplicated properties and tracks 7 times more property advertisements than any standalone platform or portal.

- **Deduplicated properties.** Each property is counted once, no matter how many agency websites and portals advertise it. The 40% figure therefore compares properties with properties, not advertisements with advertisements.
- **Advertisements tracked.** Casafari collects advertisements from agency websites and portals as they appear and as they change, and merges all of a property's advertisements into its single record.
- **One record per property.** Each record keeps the property's full, dated history: every price change, status change, appearance and removal.
