Chilly-Mazarin Property Prices, Rents & Rental Yields

About Chilly-Mazarin

Chilly-Mazarin, in the Essonne department south of Paris, sits in a practical commuter corridor with local services, nearby employment links, and access to the wider Île-de-France urban area. For apartment investors, it offers a suburban setting shaped by everyday convenience rather than spectacle.

May 2026 brings the clearest signal: pricing has eased over the year, while rents have only nudged higher month to month. The average apartment sale price stands at €199,000, unchanged from the previous month, but down 5.5% year over year. Over the same period, the average rent is €822, up 0.9% month over month yet also down 5.5% from a year earlier.

That gap creates the month’s central tension. The average price per square metre is €2,803, flat month to month and down 14.9% year over year, which points to a softer capital value base even as rental income remains relatively steady. For a market note in May 2026, the result is a gross yield of 5.78%: not a signal of accelerating momentum, but a reminder that lower entry pricing can partially offset weaker annual rent and price trends. Investors reading the month should see a market where valuation relief is visible, while income has not strengthened enough to erase that broader moderation.
