Real estate prices in Oise: the A 1, an “asset that is not everything”. With 11.6% drop over one year, the big plunge of Meudon in Hauts-de-Seine.

Exceptional properties, a niche market that is holding up in Seine-Saint-Denis Val- de-Marne. Val-d'Oise: tranquility at a reasonable price in Les Coteaux, in Argenteuil. In the Chevreuse valley in Essonne, poorly insulated houses… and much cheaper.
