Franconville Property Prices, Rents & Rental Yields

About Franconville

Franconville, in the Val-d’Oise department north of Paris, sits on the edge of the capital’s commuter belt while keeping its own urban identity. For apartment investors, it offers a practical mix of transport-linked living, local services, and a residential setting that remains closely tied to Greater Paris.

August 2026 brings the clearest signal first: apartment pricing has softened, but rents have also eased, keeping the income picture from improving as quickly as values might suggest. The average sale price stands at €189,000, while the average m2 price is €3,150, after month-on-month declines of 4.5% and 4.6% respectively. That pullback is notable, yet the rental side has also moved lower, with the average rent price now at €980, down 7.0% over the month.

On a yearly view, the market looks steadier than the monthly figures imply. The average sale price is down 3.6% year on year, and the average m2 price is down 2.0%, while rents are essentially flat at -0.4%. Even so, the current yield of 6.79% shows that Franconville still offers a meaningful income return for apartments. The tension in August is therefore straightforward: lower entry prices are helping on valuation, but weaker rents are limiting how much the investment case can improve.
