Cergy Property Prices, Rents & Rental Yields

About Cergy

Cergy sits beside the Oise in France’s Val-d’Oise department, pairing planned urban districts with a riverside setting. That combination gives the city a distinct identity, but its apartment market still calls for a close reading of the figures.

In October 2026, the clearest signal for Cergy apartments is a monthly rise in average rent, up 7.1%. Yet that movement sits against a longer decline: average rent is down 2.7% from a year earlier. The contrast matters more than either change alone. It shows a recent increase in the rent measure without establishing an upward trend across the full year.

For investors, the stated yield of 7.07% provides a starting point, while the average apartment sale price of €212,600 anchors the purchase side of the comparison. Both deserve to be read alongside the rent pattern, rather than as proof that the latest monthly increase will persist. A stronger monthly reading may affect an immediate calculation, but the annual comparison is a reason to test income assumptions carefully.

The takeaway is to keep timing central to any assessment of Cergy apartment returns. The recent rental movement and the annual direction tell different stories, while the published yield remains a snapshot rather than a guarantee. Reading them together offers a more balanced basis for comparing investment locations without assuming that one month has reset the longer-term picture.
