A little history
The Gallo-Roman past is only visible in the presence of a road known as a Roman road which occupied the axis of the vallée de Montmorency. This important road lay on the route from Paris to Rouen, via Saint-Denis and Pontoise, and its line can be found again in the « chaussées Jules César » used as a street name in Eaubonne and Franconville to the north-west. Situated partly on the slopes of the large hill that bears the forêt de Montmorency, its land was well suited to vines and fruit trees. The lower part, at the bottom of the wide vallée de Montmorency, was marshy, so much so that the main settlement had to be established at the foot of the first slopes.

Selling in Soisy-sous-Montmorency
Pricing in Soisy-sous-Montmorency starts by placing your property inside the €2,762 to €3,855 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 167 sales a year, Soisy-sous-Montmorency absorbs correctly priced properties. An over-ambitious price shows quickly, because buyers have points of comparison.

Buying in Soisy-sous-Montmorency
Reading the €2,762 to €3,855 band is a buyer’s main tool in Soisy-sous-Montmorency. 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 down give a buyer room to discuss, provided the argument rests on comparable sales rather than on the trend itself.
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.
