In Castelnau-d'Estrétefonds, the average price of apartments stands at 2 471 €/m², based on the sales actually registered in the DVF data, the French notarised sales database. As the municipality is very largely one of detached homes, the most telling benchmark remains that of houses, which trade on average at around 2 637 €/m². That level reflects its status as a periurban municipality of the northern Toulouse area, in strong residential growth along the A62 motorway. The stock is made up above all of recent houses, carried by the new estates that have gone up over the past twenty years. Plot size, year of construction, energy performance and closeness to the motorway junction make prices vary from one property to another. These notarised figures give a municipal benchmark; a reliable valuation then rests on comparable properties, judged case by case.

Castelnau-d'Estrétefonds lives to the rhythm of the expansion of the northern Toulouse area. Demand for houses, driven by first-time buyers and by working people from the metropolitan area, bears on a municipality where land is still available and new building active. Recent estates and properties close to the station and to the motorway junction concentrate the interest of buyers, which supports prices despite a regularly renewed supply.
Build quality, plot size and energy performance now govern most of the price gaps: a recent house, well rated on its certificate and close to motorway access, sells without difficulty, while an energy-hungry or remote property takes a discount. Dependence on the Toulouse job market and the pace of new construction remain the main factors of sensitivity for the local market.
Castelnau-d'Estrétefonds sits below the municipalities of the near suburbs of Toulouse such as Blagnac or Beauzelle, but at a level close to that of its neighbour Castelginest, further south.
Castelnau-d'Estrétefonds grew up around a former castelnau, a fortified medieval village set on high ground overlooking the plain of the Garonne. The name keeps the trace of that castle and of the Roman road, the strata, which crossed the area north of Toulouse. The church and the old village still recall that early settlement.
Long a farming municipality turned towards the crops of the plain, Castelnau-d'Estrétefonds saw its fate change with the arrival of the A62 motorway and the opening up of the northern Toulouse area. Its position on the Toulouse to Bordeaux route made it a strategic site for transport and logistics activities.
The municipality is now home to Eurocentre, one of the large logistics platforms of the south-west, linked to the railway and to the motorway. That activity, combined with the land pressure of the Toulouse metropolitan area, has turned a rural village into a fast-expanding residential municipality, where the new estates have pushed the population up.
Castelnau-d'Estrétefonds has around 7 000 inhabitants, a population that has risen sharply since the 2000s under the effect of urban sprawl from Toulouse. The property market is dominated by the detached house: many buyers are young households and first-time buyers who work in the Toulouse conurbation and are looking for a house with a garden at a more affordable price than in the near suburbs. The A62 link and the railway station, together with the local logistics employment area, sustain steady demand and regular new construction.
The average price of apartments in Castelnau-d'Estrétefonds is 2 471 €/m², based on DVF transactions completed before notaries. As the municipality is mostly one of detached homes, houses form the main benchmark, with an average of 2 637 €/m². Plot size, year of construction and energy performance explain most of the gaps. A reliable valuation rests on comparable sales rather than on the municipal average alone.
The municipality benefits from its position on the A62 motorway north of Toulouse, within reach of the metropolitan area while remaining more affordable. The scarcity of land in the near suburbs of Toulouse pushes many households towards this area, where new building is still possible. That steady demand, driven by first-time buyers and by the logistics employment area, feeds a regular rise in prices.
Eurocentre is a large logistics zone set up in the municipality, linked to the A62 motorway and to the rail network. It brings together warehouses and transport activities and forms a significant employment area on the scale of the northern Toulouse region. Its presence partly explains the demographic and residential growth of Castelnau-d'Estrétefonds, where many residents work in that sector or in the Toulouse conurbation.
Supply is very largely made up of houses, often recent and set in housing estates. Apartments exist but remain in the minority, mainly near the centre and the station. A buyer looking for a house with a garden will find a wide choice here, while someone after an apartment will face a more limited offer. The right price benchmark therefore depends above all on the type of property being sought.
The municipality is served by the A62 motorway, which links it directly to Toulouse and to Montauban, and by a station on the railway line, useful for commuting. That accessibility is one of the main drivers of its residential appeal. It allows people working in the Toulouse conurbation to settle further north, in a more rural setting and at a contained housing cost.
