Apartments in Gagnac-sur-Garonne sell for an average of 2 400 €/m², according to the sales actually recorded in DVF, the database of notarised transactions. This benchmark covers a narrow market: the municipality is still made up mainly of detached houses, inherited from the old village and from the housing estates of the northern Toulouse area. Houses trade higher, at around 3 796 €/m² on average. Apartments are concentrated in a few small recent developments, close to the centre and to the roads towards Toulouse. Location, floor level, the condition of the property and its energy performance explain most of the gaps around this municipal average.

The Gagnac-sur-Garonne market is carried by the population growth of the northern Toulouse fringe, where many households look for a house with a garden at a more accessible price than in Toulouse. The Tisséo bus links towards the La Vache metro station and the Aéroconstellation tram, the closeness of the aeronautical employment areas of Blagnac and the setting on the banks of the Garonne sustain steady demand. The growing scarcity of building land, as development gains on farmed land, limits new supply and supports the value of existing houses, the core of the municipal stock.
In the medium term, membership of Toulouse Métropole and access to the employment hubs of the north-west of the urban area remain the main drivers of value. Demand is concentrated on properties that are well located and properly served, while energy performance weighs more and more in negotiations on the older stock. For a seller, a realistic and well-presented property quickly finds a buyer, whereas an over-ambitious price lengthens the process. A valuation based on comparable sales remains the best benchmark before setting a price.
Gagnac-sur-Garonne ranks among the most affordable municipalities of the northern ring for its apartments, below Castelginest, Beauzelle and Blagnac, the last of these carried by aeronautical activity.
Gagnac-sur-Garonne stretches along the right bank of the Garonne, about twelve kilometres north-west of Toulouse, over a modest territory of 434 hectares bordered by Fenouillet, Lespinasse and Saint-Jory and, on the other side of the river, by Merville and Seilh. The name ending in -ac points to a former Gallo-Roman estate, formed on a personal name followed by the suffix -acum, a pattern common in the Toulouse region. The municipality has been called Gagnac-sur-Garonne only since a decree of 30 December 1939, which added the reference to the river to its original name, Gagnac. The course of the Garonne and its plain have lastingly shaped the local land.
Long a farming village turned towards the Garonne, Gagnac has kept few old archives: during the night of 23 November 1960, at about three in the morning, a fire destroyed the roof, the floors, the classrooms and part of the municipal archives of the town hall and school, built in 1889. Local memory is kept alive today by the history workshop « Il était une fois... Gagnac ». The river has also marked the municipality through its floods, including the one of 1875, which remains in local memory. The église Notre-Dame, built in the 19th century to plans by the Toulouse architect Jacques-Jean Esquié, and the châteaux of Gagnac and Novital are among the landmarks of the municipal heritage.
The recent history of Gagnac is that of a shift into a residential municipality of the northern suburbs. The population, about 370 inhabitants in 1793 and still 813 in 1975, has been multiplied by close to four in half a century to reach 3 198 inhabitants in 2023. Farmed land has gradually given way to housing estates as the Toulouse urban area spread northwards. Part of Toulouse Métropole and attached to the canton of Castelginest since 2015, the municipality remains linked to the central city by the Tisséo bus routes, among them route 59 towards the La Vache metro station, while the Saint-Jory railway station, a few kilometres away, completes the rail service.
Gagnac-sur-Garonne has 3 198 inhabitants, according to INSEE, the French statistics institute, in a municipality where the detached house remains in the majority: the stock was split, according to INSEE, between about 61 % houses and 39 % apartments, with a very large share of main residences, close to 94 %, and a majority of owner-occupiers, around 60 %. The market is aimed first at families and at households buying their home, looking for a house with a garden at a price more measured than in Toulouse while staying a quarter of an hour from the central city. The few apartments mainly attract first-time buyers. Transport links, location and the presence of outdoor space weigh heavily on the value of one property compared with another.
The average price of apartments in Gagnac-sur-Garonne is 2 400 €/m², according to DVF transactions actually registered with notaries. This average covers a narrow market, since the municipality counts mostly houses, which trade higher, at around 3 796 €/m². Location, floor level, the condition of the home, the links towards Toulouse and the energy rating explain the gaps. For a specific property, a valuation based on comparable sales remains more reliable than the municipal average alone.
Gagnac is above all a municipality of houses: according to INSEE, about 61 % of homes are detached houses, inherited from the old village and from the housing estates. Apartments, which are rarer, are found mainly in small recent developments. The benchmark price of 2 400 €/m² concerns apartments; houses trade higher, at around 3 796 €/m² on average, but their value depends above all on the plot, the floor area, the condition and the location, and is assessed case by case.
Gagnac lies about a dozen kilometres north-west of Toulouse. Several Tisséo bus routes serve the municipality: route 59 reaches the La Vache metro station, and route 130 leads to the Aéroconstellation tram stop, next to the aeronautical zone. The Saint-Jory railway station, about six kilometres away, completes the rail service towards Toulouse-Matabiau. This accessibility and the closeness of the employment areas of the northern Toulouse fringe support demand for housing.
The municipality keeps the character of a village on the banks of the Garonne, with its église Notre-Dame from the 19th century and its two châteaux. The riverbanks, crossed by a footbridge, offer popular walks, and a lake completes the leisure areas. Schools, local shops and facilities meet everyday needs. This residential setting, away from the density of Toulouse but well connected to the metropolitan area, partly explains the appeal of Gagnac for households buying their home.
The growth of the Toulouse urban area has fed continuous development in Gagnac, with housing estates and a few small apartment blocks that have densified the edges of the centre and the roads towards Toulouse. Building land is becoming scarce as farmed land recedes, which supports the value of the existing stock. Energy performance is becoming a negotiating criterion on older properties. To sell at the right price, it is better to start from a valuation based on recent, comparable sales than from a price set at random.
