The Mont-de-Marsan market is that of a mid-sized prefecture with a sound market. With an average price of around 2 126 €/m² for an apartment and 181 sales a year, Mont-de-Marsan sits well below Bordeaux and Bayonne, but clearly above the prefectures of central France. The price gains 11 % over five years and 3,1 % over the last twelve months: steady growth, without jolts.
The striking fact is not the gap between districts, it is the absence of one. Eighteen per cent separate Beillet from Nonères, while most French towns show 100 % or more. Two explanations combine: a compact commune, where no district is truly far from the centre, and a uniform housing stock, largely built in the same period. The direct consequence for a seller: in Mont-de-Marsan, value turns on the property rather than the address. Four published districts remain under fifteen apartment sales a year, Beillet and Saint-Jean-d'Août in particular. On those pages, take the average of the last two years rather than the movement of the latest one alone.
Mont-de-Marsan compared with the largest French cities, on the average price per m² for an apartment.
Mont-de-Marsan was established on the spur formed where the Midou and the Douze meet to become the Midouze. Viscount Pierre de Marsan founded a chartered town there in the twelfth century and granted privileges to attract residents. The walled town, protected by the natural moat of the two rivers and run by a council of jurats, became a trading place.
What remains of it are the Romanesque houses of rue Lacataye, among the oldest surviving civil houses in France. Two of them, joined together and built into the town wall, form the Lacataye keep, which today houses the Despiau-Wlérick museum, devoted to French figurative sculpture. The Plumaçon bullring and the Madeleine festival established the town in the culture of the Landes, and air base 118, nearly 700 hectares in the north of the commune, made it a military employment hub from 1945 onwards.
The geography of prices, on the other hand, is remarkably flat. Beillet, Crouste and Saint-Jean-d'Août hold the top of the market, between 2 224 and 2 244 €/m². Saint-Roch, the inner centre, and Bourg-Neuf follow at 2 147 and 2 087. Nonères brings up the rear at 1 907. Between first and last there is only 18 %: in Mont-de-Marsan, the address barely makes the price.
The Mont-de-Marsan market is a prefecture market, carried by public-sector employment, the hospital, the departmental council and air base 118, to which are added food processing and timber. First-time buyers find a moderate entry ticket there by the standards of Nouvelle-Aquitaine, well below Bordeaux and Bayonne. Unusually, houses do not trade above apartments: at 2 119 €/m² against 2 126, the two markets are at the same level. In a town surrounded by forest and available land, the supply of detached houses is plentiful and such a house is not a scarce asset here.
The average price in Mont-de-Marsan is 2 126 €/m² for an apartment (actual DVF transactions, notarised sales), within a band of 1 841 to 2 418 €/m² depending on the district. Property portals display asking prices, 10 to 20 % above the prices actually recorded.
Almost. The gap between the most expensive district and the most affordable is only 18 %, one of the narrowest observed in France. Beillet sits at around 2 244 €/m² and Nonères at around 1 907 €/m². In between, four districts hold within a band of 140 euros. In this town, the condition of the property, its energy rating and its year of construction weigh more than the address.
Houses come out at 2 119 €/m² on 490 sales, against 2 126 €/m² for apartments: the two markets are at the same level, which is rare. The town is surrounded by the Landes forest and by building land, the supply of detached houses is plentiful and such a house is not a scarce asset here. Elsewhere, the gap commonly runs from 30 to 50 %.
Because the data does not exist. Barbe d'Or and Carboué record no apartment sale over two years, Saint-Médard records two: these are areas of houses, not apartment markets. Le Peyrouat, a priority neighbourhood, is a different case: its housing is social and rented, and therefore absent from sales. Those areas are covered with the neighbouring district they are attached to.
In this town, starting from the district is not enough, since the districts hold within an 18 % gap. What makes the difference is the condition of the property, its energy rating, its year of construction, the floor level and the presence of a lift or parking.
