The State, through Gérald Darmanin, Minister for Action and Public Accounts, announced at the beginning of the year the total opening in open data of the land data available on the Patrim file .

Obtaining a simple and reliable estimate of an apartment or a house is not always easy. Judging the value of a property has until now involved a significant amount of imprecision.

But the difference between the price displayed on the ad and the actual purchase price can be significant.
