Prices by property type in Bailly
Prices by property type in Bailly
By property type in Bailly, T3 at €3,711/m², T5+ at €3,976/m², T4 at €3,797/m².
The T5+ carries the highest price per square metre and the T3 the lowest, a gap of 7 %. 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.
The house is what changes hands most often here, with 18 sales over twelve months. It is therefore the type with the most reference points, and the one where a price is hardest to argue against.

Selling in Bailly
Pricing in Bailly starts by placing your property inside the €3,474 to €4,358 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 47 sales a year, Bailly 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 Bailly 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 Bailly
Reading the €3,474 to €4,358 band is a buyer’s main tool in Bailly. 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.

No five-year reading is available for Bailly. The apartment sales we currently use (2023 à 2025) do not go back far enough to compute one, so the long-term direction cannot be stated here.
Among the towns tracked by BRIVEO in the same department, on the median apartment price, Sartrouville sits 3 % below and Versailles 72 % above. Those are the gaps a buyer widening their search area actually meets.
