The studio carries the highest price per square metre and the T5+ the lowest, a gap of 51 %. 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.

Estimate my property in GuyancourtSelling in Guyancourt
Pricing in Guyancourt starts by placing your property inside the €3,294 to €4,265 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 197 sales a year, Guyancourt absorbs correctly priced properties. An over-ambitious price shows quickly, because buyers have points of comparison.

Buying in Guyancourt
Reading the €3,294 to €4,265 band is a buyer’s main tool in Guyancourt. 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.
A stable market usually means a negotiation decided by the property itself rather than by any general trend.
