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

About Rosny-sous-Bois

Rosny-sous-Bois, in Seine-Saint-Denis, sits on the eastern edge of Greater Paris with a residential feel shaped by local services, transport links, and a mix of urban convenience and neighborhood calm. For investors focused on apartments, it offers a market that is easy to read but not static.

July 2026 brings the clearest signal: prices are still moving up, while rental momentum has softened. The average apartment sale price reached €267,750, after rising 1.0% over the month and 4.5% over the year. At the same time, the average rent price eased to €890, down 1.7% month on month and 3.8% year on year. That divergence is the main story this month, because it points to stronger capital values without matching rental growth.

The pricing picture reinforces that tension. Average values stand at €4,340 per m2, up 0.9% from the previous month and 5.8% above last year’s level. Against that backdrop, the current yield of 5.35% suggests an income return that remains meaningful, but one that is being tested by firmer purchase prices and weaker rents. For a July 2026 snapshot, Rosny-sous-Bois looks like a market where appreciation is intact, yet investor economics are being squeezed by the gap between sale prices and rental performance.
