Les Coteaux is the most sought-after district in Argenteuil alongside that of Orgemont-La Colonie. Prices remain generally attractive compared to neighboring towns such as Colombes, Nanterre, Sartrouville or Sannois.
In the Chevreuse valley in Essonne, poorly insulated houses… and much cheaper. In Seine-et-Marne, before the opening of line 15 south, now is the time to buy in Champs Yvelines.
