A little history
The date of settlement of the first populations in the vallée de Montmorency and on the site of Ermont can be estimated as the Neolithic period. A Gallo-Roman village was established on the Roman road from Lutèce to Juliobonna (Lillebonne near Le Havre) known as the «chaussée Jules César». It was destroyed at the end of the 3rd century during the Germanic incursions and then rebuilt in the 4th century. It prospered during the Merovingian period in the 6th and 7th centuries.

The studio carries the highest price per square metre and the T5+ the lowest, a gap of 45 %. 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 Ermont
Pricing in Ermont starts by placing your property inside the €3,079 to €4,426 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, Ermont absorbs correctly priced properties. An over-ambitious price shows quickly, because buyers have points of comparison.
Briveo values your Ermont 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 Ermont
Reading the €3,079 to €4,426 band is a buyer’s main tool in Ermont. 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.
