Property tracker app for France — track against the Notaires-INSEE index

Why use the Notaires-INSEE index

The Indice Notaires-INSEE is France's official residential property price index. It's compiled jointly by the Conseil supérieur du notariat (which sees every property transaction in France) and INSEE (the national statistics office), and published quarterly.

Because notaries are required by law to record every real estate transaction, the index is built from the most complete property transaction dataset in Europe — covering apartments and houses, with regional breakdowns for Île-de-France, Province, and each of the major French regions.

SeLoger and Meilleurs Agents publish estimates based on listings and algorithmic models. The Notaires-INSEE index is based on actual recorded transactions.

How WealthMap tracks French property

Enter your French property: region (Île-de-France, PACA, Auvergne-Rhône-Alpes, etc.), property type (apartment or maison), purchase date, purchase price. WealthMap applies the Notaires-INSEE index change for your region and type since purchase.

Example: an apartment in Paris bought in June 2019 for €580,000. The Paris apartment index rose roughly 4.2% by January 2026 (after the 2022-2024 price correction). WealthMap shows your current value as €604,360 with a +4.2% gain — plus a chart of how it tracked through every quarter.

Data is pulled from INSEE on-device. No subscription. No third-party scraping.

Île-de-France, Paris, and regional breakdowns

Notaires-INSEE publishes the index with distinct breakdowns for: Paris (the 20 arrondissements aggregated), Petite Couronne (92, 93, 94), Grande Couronne (77, 78, 91, 95), and Province (the rest of France). Within Province, there are further regional breakdowns.

WealthMap supports each of these granularities — your Paris 11ème apartment tracks against the Paris index, not the Province average.

Beyond French property

If you're a French resident with property abroad — a Barcelona apartment, a London flat, a Lisbon townhouse — WealthMap tracks each one against its own country's official index. The dashboard aggregates everything in EUR.
