Mood illustration of Montesson, a municipality in the loop of the Seine, in the Yvelines.
In Montesson, the average price of an apartment comes out at 4 237 €/m², according to the sales actually registered in the DVF database kept by notaries. The market for houses sits higher, at around 5 549 €/m², a marked gap that reflects the very residential nature of the municipality, where the detached house with a garden dominates. That level places Montesson in the upper range of the Yvelines, below the most prestigious municipalities of the loop but well above the departmental average. Demand is concentrated on detached houses, rarer and more sought after than apartments. The location, the closeness of the Seine and of the stations, the condition of the property and its energy performance explain most of the gaps. Drawn from the transactions signed before notaries, these figures give a reliable benchmark; a precise valuation then rests on comparable sales, examined property by property.

The Montesson market is that of a highly rated residential municipality of the loop of the Seine, sensitive to the Paris-region economic climate and to changes in lending rates. Demand is concentrated on detached houses, rare and sought after, which supports their value above that of apartments. Energy performance has become an important bargaining criterion, including on older detached homes, where the worst-rated properties sell at a discount.
Belonging to a prized sector of the western Paris region and the protection of the market-gardening plain support the value of well-placed properties, close to the Seine and to the stations. For a seller, a house correctly valued and presented finds a buyer on a tight market, whereas an over-ambitious price settles in for the long haul. The suburban districts close to green spaces remain the most highly valued in the medium term.
Montesson shares the residential profile of its neighbours in the loop of the Seine, a little above Sartrouville and below the most highly rated municipalities such as Chatou or Le Vésinet.
Montesson occupies a fertile alluvial plain, on the right bank of the Seine, inside a wide loop of the river some fifteen kilometres from Paris. The old heart of the village keeps its church of Saint-Wandrille and its old houses, witnesses to a rural past long turned towards the land. The name of the municipality remains associated with its plain, one of the few farmed spaces preserved in the near suburbs of Paris.
The plain of Montesson is market-gardening land whose tradition goes back to the 17th century. On around three hundred and fifty hectares hemmed in by built-up areas, market-gardening families still grow salads and vegetables: the plain provides a sizeable share of the Paris region's salad output, an unusual feature for a municipality of the inner ring of the Yvelines. That farmed space, which is protected, still shapes the identity and the landscape of the town.
Over the course of the 20th century, Montesson became largely urbanised under the effect of the expansion of the western suburbs, while preserving its plain. The municipality, part of the Saint-Germain Boucles de Seine conurbation, today combines sought-after suburban districts, an old centre and that vast market-gardening area. Surrounded by prized towns of the loop of the Seine, it shares their residential setting and their closeness to green spaces.
Montesson has close to 14 500 inhabitants and ranks among the sought-after residential municipalities of the loop of the Seine. The market there is dominated by detached houses, targeted by well-off families who work in Paris or at La Défense and favour a green setting, close to the Seine and to its market-gardening plain. Buyers look for space, quiet and the quality of the schools, while staying within reach of the stations that serve the capital. Apartments, fewer in number, attract households that aim for the municipality for its setting without being able to reach the market for houses. Demand remains steady, carried by the general appeal of the western Paris region.
The average price of an apartment in Montesson is 4 237 €/m², according to DVF transactions actually completed before notaries. That average covers varied properties, from the older apartment to the recent home in a modern development. The storey, the condition, the energy performance and the closeness of the stations explain the gaps around that value. A reliable valuation rests on comparable sales rather than on the municipal average alone.
The market for houses in Montesson sits at around 5 549 €/m², clearly above apartments. That gap owes to the residential nature of the municipality, where the detached house with a garden is the most sought-after and the rarest property. The size of the plot, the location within the loop of the Seine, the condition and the energy performance make that price vary widely from one house to another. A precise valuation rests on comparable sales in the same sector.
Montesson combines the closeness of Paris and of La Défense, a green setting marked by the Seine and its preserved market-gardening plain, and housing that is mostly made up of detached homes. The quality of the schools and the quiet of the residential districts appeal to well-off families of the western Paris region. That appeal supports steady demand, in particular on houses.
The plain of Montesson, protected and given over to market gardening, limits the urbanisation of part of the territory and preserves a green setting that is rare in the near suburbs. That distinctive feature strengthens the residential appeal of the nearby districts, which enjoy an open environment. It contributes to the image of the municipality and supports the value of the properties close to those open spaces.
