Chilly-Mazarin, the town
Chilly-Mazarin covers 5.6 km², lies between 42 and 101 m above sea level and had 20,443 inhabitants in the 2023 census.
Chilly-Mazarin (pronounced [ ʃili mazaʁɛ̃]) is a French commune situated eighteen kilometres south of Paris in the département of l'Essonne in the Île-de-France region. Connected to Lutèce as early as the 3rd century by an aqueduct, Chilly-Mazarin was from the Middle Ages the estate of important families and then of celebrated noblemen who endowed it with châteaux, among them the heirs of Cardinal Jules Mazarin who gave it its name.
A little history
The discovery on the territory of an arrowhead, scrapers and Neolithic blades, and the burial of a woman, establish that the site was occupied as early as that period. During the Gallo-Roman period in the 3rd century under the reign of Septime Sévère, the springs were tapped to supply Lutèce with water. An underground channel flowed northwards to discharge into a collecting basin situated to the north-east of the present-day communal territory of Wissous, which received spring water from Wissous and Rungis and from which the aqueduct departed. In the 8th century, the local population divided its activity between viticulture and the growing of wheat.

Selling in Chilly-Mazarin
Pricing in Chilly-Mazarin starts by placing your property inside the €2,188 to €3,178 band rather than on the median alone. The median describes the middle of the market; condition, floor, outdoor space and energy rating decide where in the band you sit.
With 230 sales a year, Chilly-Mazarin absorbs correctly priced properties. An over-ambitious price shows quickly, because buyers have points of comparison.
Briveo values your Chilly-Mazarin property from the same DVF file, keeping only sales of comparable properties closest to your address, free of charge and with no obligation, then supports the sale through to the deed.
Buying in Chilly-Mazarin
Reading the €2,188 to €3,178 band is a buyer’s main tool in Chilly-Mazarin. A property at the bottom is not a bargain and one at the top is not a rip-off, the band measures how different the properties are, not how well they are priced.
Prices moving up narrow the room for negotiation without closing it, a property that has been on the market a long time is negotiable whatever the trend says.
Acquisition costs are budgeted on top of the price, around 8 % on an existing property, around 3 % on a new one. These are orders of magnitude; the notary computes the exact amount.
