A little history
The earliest evidence of human occupation around the current territory of Sannois dates from the Middle Palaeolithic (numerous tools in knapped stone). These were discovered at the lieu-dit le Puits-Gohier, on the site of the current A15 interchange, during excavations carried out in the former Poliet-et-Chausson quarries. These remains, the oldest discovered in the Montmorency valley, consist of several thousand pieces of flint or sandstone, including scrapers, bifaces, points and blades. Neolithic artefacts have been recorded at the lieu-dit Le Pré-Brochet, and Gallo-Roman remains are said to have been observed in the rue Damiette.

By property type in Sannois, T3 at €3,069/m², T2 at €3,780/m², T4 at €2,750/m², studio at €3,967/m², T5+ at €2,229/m².
The studio carries the highest price per square metre and the T5+ the lowest, a gap of 78 %. Small units usually cost more per square metre than large ones, because the price of a kitchen and a bathroom is spread over fewer metres.

Selling in Sannois
Pricing in Sannois starts by placing your property inside the €2,508 to €3,924 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 278 sales a year, Sannois absorbs correctly priced properties. An over-ambitious price shows quickly, because buyers have points of comparison.
Briveo values your Sannois 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 Sannois
Reading the €2,508 to €3,924 band is a buyer’s main tool in Sannois. 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.
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.
Prices moving down give a buyer room to discuss, provided the argument rests on comparable sales rather than on the trend itself.
