Cergy Property Prices, Rents & Rental Yields

About Cergy

Cergy, in the Val-d’Oise department, sits within the greater Paris orbit yet keeps a distinct identity shaped by its university presence, waterfront spaces, and planned urban core. For apartment investors, it combines a suburban setting with a metropolitan connection that continues to define its appeal.

August 2026 brings the clearest signal: pricing has softened again, while rental income has held up better. The average apartment sale price stands at €210,000, with the average price per square metre at €3,310, both down 4.1% month over month and down 5.3% and 7.4% year over year respectively. That downward adjustment in capital values is the month’s main feature.

Against that backdrop, the rental side looks more resilient. The average rent is €740, slipping just 1.5% over the month but still up 6.6% compared with a year earlier. That leaves the current yield at 5.7%, which helps explain the tension in Cergy this month: lower entry prices may improve positioning for buyers, yet the recent annual decline in sale values has been sharper than the rental correction. For apartment investors, August reads less like a growth month and more like a recalibration, with income holding steadier than prices.
