The idealista property price index
In July 2026, idealista updated the methodology of its housing price index to adapt it to market changes. The platform’s new filters make it possible to detect and exclude from the calculation products that do not reflect the conventional residential market, such as seasonal or holiday rentals. The identification of outliers has also been strengthened using more robust statistical techniques. To ensure that the data remain comparable, the new methodology has been applied retroactively to the entire historical series.
The data were collected and analysed by idealista/data, idealista’s proptech arm, which provides information for professionals to support strategic decision-making in Spain, Italy and Portugal. To deliver valuation, investment, acquisition and market analysis services, it uses all the parameters of the idealista database in each country, as well as other public and private sources.
