Franconville Property Prices, Rents & Rental Yields

About Franconville

Franconville sits in Val-d’Oise just northwest of Paris, combining suburban living with direct access to the wider Île-de-France orbit. Its apartment market reflects that position: connected, established, and shaped by steady metropolitan spillover rather than isolated local dynamics.

September 2026 brings the clearest signal in the apartment segment: prices are edging higher month to month, but the annual picture still points lower. The average sale price reached €189,900, up 0.5% over the month, while the average price per square metre eased to €3,120, down 0.9%. That combination suggests a market that is not sliding in a straight line, yet is still working through a softer valuation backdrop than a year ago.

For investors, the key tension is between income and capital values. The average rent is €930, down 5.0% month over month and 2.1% year over year, while the yield stands at 6.18%. In practical terms, the rental line is under some pressure even as sale prices are not falling sharply in the short term. The result is a September market where the income case remains visible, but tighter rent levels appear to be limiting how far valuation recovery can run.
