Boulogne-Billancourt, the town
Boulogne-Billancourt covers 6.2 km², lies between 28 and 40 m above sea level and had 119,019 inhabitants in the 2023 census.
Boulogne-Billancourt (prononcé) is a French commune in Hauts-de-Seine and the métropole du Grand Paris in the Île-de-France region, the third most populous commune in Île-de-France after Paris and Saint-Denis. It results from the union, carried out under the name of Boulogne-sur-Seine in 1790, of Boulogne-la-Petite, a parish established in 1343 around the église Notre-Dame de Boulogne sur Seyne, and the right bank of Saint-Cloud.
A little history
The future Boulogne was in the Early Middle Ages a green and wooded countryside where, around 630, the pont de Saint-Cloud stood, and around 841, the royal gibbet. From 1109, a hamlet of woodcutters from the parish of Auteuil, Les Menuls-lès-Saint-Cloud, was transformed into a wine-growing village, illustrating the Capetian renaissance extolled in 1260 by the construction on its communal land by sainte Isabelle of the abbaye de Longchamp, the future centre of the cultural life of the Parisian aristocracy, and which culminated locally in 1330 with the erection at its southern edge of the église Notre-Dame by Philippe le Long.

Prices by property type in Boulogne-Billancourt
By property type in Boulogne-Billancourt, T3 at €8,205/m², T2 at €8,287/m², studio at €8,659/m², T4 at €8,558/m², T5+ at €9,032/m².
The T5+ carries the highest price per square metre and the T3 the lowest, a gap of 10 %. 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 T3 is what changes hands most often here, with 464 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 Boulogne-Billancourt
Pricing in Boulogne-Billancourt starts by placing your property inside the €7,250 to €9,596 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 1,638 sales a year, Boulogne-Billancourt absorbs correctly priced properties. An over-ambitious price shows quickly, because buyers have points of comparison.
Briveo values your Boulogne-Billancourt 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 Boulogne-Billancourt
Reading the €7,250 to €9,596 band is a buyer’s main tool in Boulogne-Billancourt. 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.
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.
