Apartments in Montgeron sell at an average price of around 3 719 €/m², based on transactions actually recorded (DVF data, the French database of sales registered before notaries). Prices run from around 3 518 €/m² in Chalandray to 4 155 €/m² in Saint-Hubert, a gap of only 18 %: this is the most uniform market we have measured recently. A house, at 4 005 €/m², sells 8 % above an apartment, in a town where detached houses make up 52,5 % of the housing stock. With 95 apartment sales a year, the volume is solid.

The average price per m² for an apartment in each district of Montgeron covered by Immover, ranked from the most expensive to the most affordable.
The Montgeron market is perfectly flat over five years. The average apartment price was 3 722 €/m² in 2021, it stands at 3 719 in 2026, and it is down 1,1 % over the last twelve months. With 95 apartment sales a year and 190 transactions retained for 2024 and 2025, the volume makes those figures solid. Three of the four published districts are falling over twelve months, Chalandray by 6,2 %, La Gare by 2,4 %, Saint-Hubert by 0,9 %. The only notable rise over five years is that of Le Nouzet, at 16 %, but it rests on ten sales a year.
Two features set this market apart. The first is its uniformity, the strongest we have measured recently: 18 % separate the most expensive district from the most affordable, against 31 % in Libourne, 35 % in Orly and 61 % in Laon. Montgeron is a residential town with no large post-war estate and no dense old centre, and its price geography is flat. The second is the role of land. The Sénart forest covers a large share of the municipal area, which limits what can be built and supports the value of the existing stock, in particular on the south-eastern edge where the most expensive district lies. That is the factor to watch in the coming years, more than the economic cycle.
Montgeron compared with the major French cities, on the average price per m² of an apartment.
Montgeron is a town of the forest edge. It occupies the rim of the plateau between the Sénart forest, to the south and the east, and the Yerres valley, which separates it from Crosne and from Yerres. That position explains its building stock: little older flatted housing, a great deal of low-rise detached housing, tree-lined avenues and estates from the late nineteenth and the twentieth century rather than a medieval centre.
One event gave it national standing. On 1 July 1903, at 15:16, more than seventy riders set off from the route de Corbeil for the first stage of the first Tour de France. The checkpoint was set up in front of the Réveil-Matin inn, whose name is in fact misleading: the start was not given in the morning but in the middle of the afternoon. Only a third of the starters reached the Parc des Princes on 19 July. The establishment still stands, and « réveil matin montgeron » remains, with eight hundred searches a month, the most searched name in the town.
The station did the rest. Montgeron-Crosne, on the RER D, puts Paris-Gare de Lyon around twenty minutes away and recorded 3 933 989 passengers in 2024, which makes it one of the busiest stations in the Essonne. Part of that traffic comes from Crosne and the neighbouring towns, the station being shared. Note that this figure is slightly down on 2019, when it reached 4 074 620.
The Montgeron of today is a well-off and stable residential town. The median income reaches 28 860 euros, unemployment as measured by the census 9,9 %, and 60,5 % of residents own their home. The population is growing slowly, by 0,2 % a year since 2017. The Sénart forest covers a large share of the municipal area, which limits the supply of building land and explains part of the price level.
Montgeron is bought for a precise trade-off: the Sénart forest and its detached houses on one side, the RER D and Paris twenty minutes away on the other. The dominant profile is that of families from the Paris region looking for a house or a large apartment with outside space, in a town where 60,5 % of residents already own their home and where the median income reaches 28 860 euros. It is the most well-off and the most stable of the four towns we have opened today. Three points to know before buying. The first is uniformity: only 18 % separate the most expensive district from the most affordable, the smallest gap in our recent readings. In Montgeron the address counts for little, it is the property that makes the price, and that is the first piece of advice we give to a seller as much as to a buyer. The second is that the market is flat and slightly tilted downwards: down 1,1 % over twelve months, and three districts out of four falling. You do not buy here for an automatic capital gain. The third is land: the Sénart forest covers a large share of the area, which limits what can be built and supports the value of the existing stock, in particular on the south-eastern edge.
The average price in Montgeron is 3 719 €/m² for an apartment (actual DVF transactions, notarised sales), within a range of 3 083 to 4 406 €/m² depending on the district. Property portals show asking prices, 10 to 20 % above the prices actually recorded.
Yes. On 1 July 1903, more than seventy riders set off from the route de Corbeil for the first stage, with the checkpoint set up in front of the Réveil-Matin inn. One detail is made necessary by the name of the establishment: the start was not given in the morning but at 15:16. Only a third of the starters reached the Parc des Princes on 19 July.
Saint-Hubert, in the south-east on the edge of the Sénart forest, at 4 155 €/m², that is 12 % above the town average and 18 % above Chalandray. It is also the most active district, with thirty-one apartment sales a year, a third of the market of the town. The forest edge and the limited supply of building land explain most of that gap.
Around twenty minutes to Paris-Gare de Lyon on the RER D, from Montgeron-Crosne station. That station recorded 3 933 989 passengers in 2024, which makes it one of the busiest in the Essonne, part of its traffic coming from Crosne and the neighbouring towns. By car, the N6, the A6 and the Francilienne are a few minutes away.
Eighteen per cent alone separate Chalandray from Saint-Hubert, where a comparable town sits closer to 35 %. The reason is the nature of the housing stock: Montgeron is a uniform residential town, 52,5 % of it low-rise detached housing, with no large post-war estate and no dense old centre to create gaps. In practice that means the property counts for more than the address, and that a district-level valuation is less informative here than elsewhere.
Seven sectors out of eleven do not record enough single-lot apartment sales for a price to be defensible. Two of them are almost entirely forest. Another, La Pelouse, misses the threshold by four transactions only. The most striking case is the Réveil-Matin sector, which carries the most searched name in the town but records only eighteen sales in five years. We do not publish a price where the market does not support one.
A house costs 4 005 €/m² against 3 719 for an apartment, that is 8 % more, and detached houses make up 52,5 % of the housing stock of the town: the supply genuinely exists. Watch the calculation convention, which matters more here than elsewhere. The price per square metre of a house covers the built floor area while the value paid includes the land, which is misleading in a town with generous plots. Some portals, applying other conventions, in fact place houses below apartments.
