It is the chief town of its canton as well as the economic, commercial, cultural and university heart of the communauté d'agglomération de Saint-Quentin-en-Yvelines.

A little history
Originally, the territory corresponding to the present-day commune of Montigny-le-Bretonneux was entirely covered by the Forêt de l'Yveline, which stretched from the Seine to the west of Paris as far as the Loire around Orléans. From the 11th century onwards, extensive land clearances were carried out by monastic orders and great lords, and villages came into being. The first mention of a village on the territory of Montigny dates back to 1204, when a cartulary containing the transcription of property deeds of the Catholic Church refers to the village of Montegni or Montani, built around a church dedicated to Saint-Martin.

Selling in Montigny-le-Bretonneux
Pricing in Montigny-le-Bretonneux starts by placing your property inside the €3,198 to €4,345 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.

Buying in Montigny-le-Bretonneux
Reading the €3,198 to €4,345 band is a buyer’s main tool in Montigny-le-Bretonneux. 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.
