This page explains, in plain language, where France's price figures on Map Syndicat come from, how they were calculated, how fresh they are, and what they do not say.
The figures on this site are medians computed from the site's own price records — asking prices collected before the listings were removed — frozen as a snapshot on 5 November 2026. The site shows no live listings and collects no listings from third-party sources. No figure is updated: a figure from 2026 describes the market as it stood then, not today.
No frozen sale-price medians exist for France on this site: no city or district sale price pages are published for France, and the France city pages show no price figures. French sale price figures do not exist here — they are not estimated or borrowed from elsewhere. To buy in France, the buy page and the buying guide explain the steps; the costs are on the buying-costs page.
Median asking rent per square metre and median monthly rent in Paris, Marseille, Lyon, Toulouse, Nice, Nantes, Bordeaux and Lille, from the site's own rent records, frozen on 5 November 2026. Each rent city page shows its sample (N) and its data-as-of date. These are asking rents, not agreed rents. Rent pages show the price per square metre only, never a verdict on whether a price is good or bad.
The rates and amounts on the buying-costs page were checked against their sources on 4 November 2026. They are 2026 rates: do not carry a 2026 rate into 2027 without re-checking. Confirm the exact amount for your purchase with a notary before signing.
The median is the middle value: half of the records in the group ask more per square metre, and half ask less. A median based on a small sample moves easily when a few records change, so read small-sample figures with extra care.
No figure is a transaction price, a live price, a valuation of a specific property, or a promise of price growth, rental income, or easy resale. Size, exact location, floor, age, and condition all move a real price away from a city or district median. Before deciding anything, visit the property, check the papers, and compare several recent comparable prices.
