Montmagny, the town
Montmagny covers 2.9 km², lies between 36 and 115 m above sea level and had 15,105 inhabitants in the 2023 census.

A little history
The oldest remains are axes, a bronze bracelet and a small vase dating from the Bronze Age, discovered in a gypsum quarry near the Barrage. In the 19th century, a Gallo-Roman villa, unfortunately not located, is said to have yielded numerous objects, among them an iron axe in the shape of a crescent. The lieu-dit le Camp is mentioned as recalling the site of a Roman camp. The first mention of the village dates back to 1090, when Hervé de Montmorency (+ 1094), lord of Montmorency and Marly, « bouteiller » of France, granted to the abbaye Saint-Florent de Saumur (Maine-et-Loire) the tithe of the alleux or freehold lands of Montmagny.

By property type in Montmagny, T3 at €2,768/m², T2 at €3,203/m², studio at €3,867/m², T4 at €2,501/m².
The studio carries the highest price per square metre and the T4 the lowest, a gap of 55 %. 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 Montmagny
Pricing in Montmagny starts by placing your property inside the €2,398 to €3,459 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 117 sales a year, Montmagny is regular without being deep. Positioning matters more here than in a dense market, because a buyer who steps back is not immediately replaced.
Briveo values your Montmagny 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 Montmagny
Reading the €2,398 to €3,459 band is a buyer’s main tool in Montmagny. 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.
A stable market usually means a negotiation decided by the property itself rather than by any general trend.
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.

Among the towns tracked by BRIVEO in the same department, on the median apartment price, Sarcelles sits 29 % below and Bezons 38 % above. Those are the gaps a buyer widening their search area actually meets.
