Poissy Property Prices, Rents & Rental Yields

About Poissy

Poissy combines riverside living on the Seine with a strong western Paris connection, while its historic core and modern residential areas give the city a layered appeal. For apartment investors, it is a place where local character and commuter convenience meet in a compact Yvelines setting.

August 2026 brings the clearest signal yet: apartment pricing has softened, while rental returns remain comparatively steady. The average sale price is €259,500, after a 3.9% monthly decline and a 7.0% drop year over year, and the average price per m² now stands at €3,990, down 3.9% on the month and 8.3% over 12 months. That move puts the market in a more cautious valuation phase.

The income side has eased too, but less sharply. Average rent is €910, down 2.5% from July and 1.9% lower than a year ago. Even so, the estimated yield is 5.43%, which suggests the gap between falling prices and still-resilient rents is supporting investor maths for now. In other words, Poissy’s apartment market is currently defined less by momentum than by an adjustment in pricing, with the rental stream not yet falling as fast as asset values.
