A little history

Montbonnot was a wine-producing village until the middle of the 20th century. Montbonnot le bas experienced unprecedented economic development in the 2000s. Extending the Inovallée zone of Meylan (then known as ZIRST), many businesses set up there, such as Sun for example. The face of Montbonnot le bas then changed completely, and within a few years the rural landscape gave way to a modern industrial zone dotted with recently built housing.

Selling in Montbonnot-Saint-Martin

Pricing in Montbonnot-Saint-Martin starts by placing your property inside the €3,604 to €4,600 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 61 sales a year, Montbonnot-Saint-Martin 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 Montbonnot-Saint-Martin 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 Montbonnot-Saint-Martin

Reading the €3,604 to €4,600 band is a buyer’s main tool in Montbonnot-Saint-Martin. 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 up narrow the room for negotiation without closing it, a property that has been on the market a long time is negotiable whatever the trend says.

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.
