The church of Saint-Saturnin, the oldest monument in Gentilly.
The average price of an apartment in Gentilly stands at around 5 901 €/m². That level reflects the position of the municipality, at the southern gates of Paris, immediately bordering the 13th and 14th arrondissements. The housing stock is overwhelmingly made up of flats, with a notable share of social housing and condominiums from the 1960s to 1980, complemented by more recent schemes. Town houses, inherited from the village of the Bièvre valley, remain rare and trade apart. Closeness to Paris and the RER B service explain a good part of the value of properties. This benchmark comes from the sales signed before notaries, recorded in the DVF database. It is a municipal average, to be refined on comparable properties for your valuation.

Demand in Gentilly is structurally supported by the immediate closeness of Paris. Buyers who cannot position themselves in the capital fall back on the bordering municipalities of the Val-de-Marne, of which Gentilly is one, with around a hundred transactions a year. The RER B service and direct access to the ring road remain the first arguments of prospective buyers.
On the supply side, a stock that is mostly flats and often old puts energy performance at the forefront of negotiations: the best-rated homes go faster, the worst performers call for room to bargain. The coming transformation of the Sanofi site and the development plans for the sector could change some districts. Buyers most often arbitrate between Gentilly and the neighbouring municipalities of southern Paris, at equivalent service levels.
Bordering Paris and several municipalities of the Val-de-Marne, Gentilly sits in the middle of this dense sector of southern Paris, below the values of the municipalities closest to the capital.
Gentilly grew up in the valley of the Bièvre, whose course long turned mills and tanneries. The river, a source of industrial nuisance, was covered over at the start of the 1950s. That past as a village by the water, at the gates of Paris, inspired painters and engravers before the urbanisation of the 20th century.
The church of Saint-Saturnin is the oldest monument in the municipality. It stands on the remains of a 7th century abbey, founded on an estate given by King Dagobert. The present building dates from the 13th century, reworked in the 16th century after the collapse of the nave, and was listed as a historic monument in 1991.
In the 17th century, the aqueduc Médicis, meant to supply water to the left bank of Paris, was built and still crosses the territory of Gentilly. Industrialisation and then urbanisation went on to densify the municipality. The research site of the Sanofi group, long a reference employer, was the subject of a closure announcement at the end of 2024, planned for 2027.
Gentilly has around 19 963 inhabitants on a dense territory bordering Paris. The housing stock is dominated by flats, with a large share of social housing and post-war condominiums. Buyers are above all first-time buyers and people working in Paris, drawn by prices more measured than in the capital and by the RER B service. The few town houses of the old village appeal to families looking for outdoor space close to Paris.
The average price sits at around 5 901 €/m² for an apartment. That municipal average covers real gaps depending on the sector, the period of construction, the storey and energy performance. An older condominium and a recent scheme close to Paris are not valued in the same way. For a reliable figure, a valuation based on comparable sales in the same district remains preferable.
The municipality is organised around its old centre, the Val-de-Bièvre and the districts close to the gates of Paris, bordering the 13th and 14th arrondissements. The sectors nearest the capital and the RER B concentrate a good share of demand. The old village, around the church of Saint-Saturnin, keeps a more residential character.
The municipality is served by the RER B at the Gentilly stop and directly adjoins Paris by way of the ring road. The T3a tram runs along the very close Paris boundary. That immediate access to the capital is one of the main drivers of local prices.
Houses exist but remain rare, inherited from the old village of the Bièvre valley. They are concentrated in a few residential sectors and trade at levels distinct from those of apartments. The great majority of transactions involve flats. The choice depends on your budget and calls for a valuation on genuinely comparable properties.
Its position at the southern gates of Paris, bordering the 13th and 14th arrondissements, makes it an alternative to the capital for many buyers. Prices there remain more measured than in Paris intra-muros, while offering fast access by the RER B and the ring road. The heritage of the Bièvre valley and the closeness of the Cité universitaire add to its residential appeal.
