Saint-Denis, Poissy, Colombes: the strongest decrees

In several cities of the small crown, prices have remittably backed away. Saint-Denis displays a fall of 9.92 %, followed closely by Colombes (- 9.86 %) and Poissy (- 8.33 %). These corrections, after years of continuous increase, are partly explained by interest rates and access to more complex credit.
