In Castanet-Tolosan, the average price of an apartment stands at 3 111 €/m². The figure covers a mixed housing stock, where recent blocks of flats built around the station and the roads towards Toulouse sit alongside a still dominant supply of detached homes, inherited from the farming village and from the housing estates of recent decades. The market remains led by the family house with a garden, but new apartment schemes have multiplied as new households have arrived. The figures rest on the DVF data, the French notarised sales database, which lists the transactions actually signed before notaries, rather than on theoretical estimates.

The Castanet-Tolosan market is carried by its position in the first ring to the south-east of Toulouse. The municipality captures demand from households working in the conurbation who are looking for more spacious housing, often a house with a garden, at a reasonable distance from the employment and research centres of the Labège area. Being close to the station and to the bus routes reinforces that appeal, particularly for families and working people who want to limit their dependence on the car.
Supply is split between an established stock of detached homes, whose properties change hands as families move, and new apartment schemes that have accompanied the growth of the population. As elsewhere in the Toulouse conurbation, energy performance has become a sorting criterion: well-rated dwellings sell more quickly, while energy-hungry properties call for a discount or for works. New-build and good-quality older stock remain the most sought-after segments, in a market that keeps a strong residential identity.
A residential municipality of the first ring around Toulouse, Castanet-Tolosan sits below Toulouse but above Blagnac and Muret, two other municipalities of the conurbation whose comparison sheds light on its position.
The name Castanet comes from the Latin castanea, the chestnut tree, which once covered the slopes of the municipality. The suffix Tolosan was officially added in 1918 to distinguish the place from the other Castanet of the region and to mark its link with nearby Toulouse. In the Middle Ages, a stronghold stood in the Broc district. The town was burnt down on 28 October 1355 during the raid led by the Black Prince, Édouard de Woodstock, and the fort was later razed on Richelieu's orders in 1626.
Castanet-Tolosan belongs to the Lauragais, a former pays de Cocagne known for growing woad and for its wheat lands, which made it one of the granaries of the Languedoc. The canal du Midi, dug under Louis XIV, crosses the municipality and has left two structures listed as historic monuments: the Castanet lock, laid out around 1670, the first oval-basin lock met when leaving Toulouse towards the Mediterranean, and the Perrier aqueduct, built between 1687 and 1689. These works recall the role of the canal in irrigating the area and in its trade.
Long a farming village, Castanet-Tolosan changed scale in the 20th century. The municipality had around a thousand inhabitants in the 1950s; it now counts more than fifteen thousand. That growth follows the expansion of the Toulouse conurbation towards the south-east and the arrival of employment and research centres nearby, notably around Labège and Auzeville. As the canton's chief town, it is one of the central municipalities of the SICOVAL, the inter-municipal authority of the south-east of Toulouse.
Castanet-Tolosan has 15 317 inhabitants, a population that has risen sharply since the 1950s under the effect of the periurban spread of Toulouse. The housing stock mixes a dominant fabric of detached homes, houses with gardens built as the estates went up, and a more recent supply of apartments, concentrated around the station and the main roads. Buyers are mostly families and working households employed in the conurbation who are looking for a greener setting some fifteen kilometres from the centre of Toulouse, along with first-time buyers drawn to new-build. The market keeps a residential and family identity, where the house remains the benchmark property even as flats gain ground.
For an apartment, the average comes out at 3 111 €/m², calculated from sales registered with notaries and published in the DVF database. It is a municipal average: it covers a recent studio near the station as much as a large apartment in a family block. Location, year of construction, floor level, aspect and the energy performance certificate explain most of the gaps. For your own property, a valuation based on comparable sales will always be more accurate than the average alone.
Both markets coexist, but the house remains the benchmark property in a municipality where detached housing dominates. Families look above all for a house with a garden, while apartments, which are more recent, appeal to first-time buyers and to households that favour being close to the station and to public transport. The choice depends mainly on your budget, on your need for outdoor space and on the distance you are prepared to put between your home and the centre of Toulouse.
The municipality lies some fifteen kilometres south-east of Toulouse and has several connections. The Tisséo network serves the town by bus, with interchanges to the metro, and a free municipal shuttle completes the offer within the municipality. The Castanet-Tolosan railway station also gives access to Toulouse by train. For car journeys, the A61 motorway and the roads towards the Toulouse ring road are within reach, which partly explains the residential appeal of the municipality.
The town centre and its surroundings, close to the shops, the schools and the station, concentrate part of the demand, particularly for apartments. The more distant estate districts, with their houses and their gardens, attract families looking for quiet. The banks of the canal du Midi offer a green setting that buyers value. Each area has its own price logic, according to how close the services are, how quiet it is and what type of property is on offer.
As everywhere, it is worth consulting the planning documents and the état des risques, the statutory natural-hazard disclosure, before a purchase, particularly for plots close to the canal or to watercourses. The energy performance of the property deserves particular attention, as it now weighs in the negotiation and in future works. Finally, for a rental project or a second home, the applicable taxation should be anticipated according to your situation.
