Gagny Property Prices, Rents & Rental Yields

About Gagny

Gagny, in Seine-Saint-Denis, sits on the eastern edge of Greater Paris with a residential feel shaped by local parks, transit links, and an established suburban fabric. For apartment investors, it is a market where practical access and neighborhood scale matter as much as headline pricing.

August 2026 brings the clearest signal: pricing has softened again, but rents have fallen too, leaving a tighter income case than the sales data alone might suggest. The average apartment sale price is €229,500, after a 2.3% monthly decline and a 6.3% drop over the year, while the average price per square metre sits at €3,830, down 0.8% on the month and 12.3% year on year. That makes the recent reset in values hard to ignore.

The monthly rent level of €900 adds to the tension. It is down 5.5% both month on month and year on year, which means the headline yield of 6.22% is being supported by lower entry costs rather than stronger rental growth. For buyers considering apartments in Gagny, the August reading points to a market that is still adjusting, with valuation pressure more visible than income momentum.
