Cachin occupies the south-east of Morsang-sur-Orge. It is one of the municipal districts defined in 1998, which take the names of the primary schools: it owes its own to the Marcel-Cachin school, built in 1954 at 2 avenue de Guise. In the north, it is organised around the avenue des Érables, the rue des Trembles, the avenue de la Forêt, the rue Lucien-Sampaix and the Compiègne-Juvisy residential estate.
In the south, the district takes in the Gribelette, a historic neighbourhood of the municipality, which extends the same grid of streets named after trees: boulevard de la Gribelette, avenue des Bruyères, avenue des Pins. The Irène-Joliot-Curie school was built there in 1957, on the rue Anne-Godeau. The Jean-Lurçat and du Progrès estates are part of the Léo Lagrange priority urban neighbourhood, recognised in January 2024.
Cachin sits at 2 265 €/m², the most affordable price in Morsang-sur-Orge, 15 % below the municipal average, with fourteen apartment sales a year. It has fallen 19 % over five years and risen 5,0 % over twelve months.
Cachin is the entry point to the Morsang-sur-Orge market, at 2 265 €/m², 15 % below the municipal average and 27 % below Le Vieux Bourg. The district combines apartment blocks in the north and the detached houses of the Gribelette in the south, two primary schools and a convenience store on the rue Lucien-Sampaix, with the Forêt market close by. The buyer profile is that of first-time buyers on a tight budget, families and investors looking for rental yield. Two points to examine. The price has fallen sharply over the period, from 2 791 €/m² in 2021 to 2 265 in 2026, a drop of 19 %, the steepest in the municipality, before rising 5,0 % over twelve months: with fourteen sales a year, the recent trend remains to be confirmed. And the range, from 1 959 to 2 366 €/m², is narrow: the gap between two properties depends mainly on the condition of the building and on the works already voted, to be checked in the minutes of the co-owners' general meetings.
