Fontenay-sous-Bois Property Prices, Rents & Rental Yields

About Fontenay-sous-Bois

Fontenay-sous-Bois, in the Val-de-Marne department east of Paris, combines residential streets, established neighbourhoods, and good everyday access to the wider capital area. Its setting gives it a steady local identity while remaining closely tied to the larger Île-de-France market.

July 2026 brings the clearest signal: apartment pricing softened, even as the rental side moved lower and kept the investment case from becoming straightforward. The average sale price stood at €354,500, after a 4.7% monthly decline and a 1.3% drop year on year. At the same time, the average rent price was €1,000, down 11.1% over the month and 4.8% compared with a year earlier.

That gap matters for investors because the current yield is 5.09%, yet it is being tested by the weaker rent trend and the lower price level. On a square-metre basis, apartments averaged €5,370, which was down 3.4% month on month but still fractionally up 0.2% year on year. Taken together, the numbers point to a market where values have eased faster than annual pricing momentum would suggest, while income has lost ground more quickly in July.
