Saint-Ouen-l'Aumône Property Prices, Rents & Rental Yields

About Saint-Ouen-l'Aumône

Saint-Ouen-l’Aumône, in the Val-d’Oise department, sits on the northern edge of Greater Paris with a practical mix of residential streets, transport links and river-adjacent green spaces. For apartment investors, it is a location where local convenience and metropolitan access meet a steady, measurable market.

September 2026 points to a clear tension in Saint-Ouen-l’Aumône’s apartment market: prices are still firm on a yearly basis, while rental returns are under pressure. The average sale price stands at €192,500, up 7.0% year on year, yet the average rent is €810, down 7.5% over the same period. That gap matters for investors because the current yield is 6.6%, a level that reflects income still available, but with less room than a year ago.

The monthly picture is more restrained. The average sale price eased 0.3% month on month, while the average m2 price moved to €3,080, up 0.6% over the month. Rents were unchanged at €810, which suggests the market is not being lifted by rental growth even as sale values remain resilient. In practical terms, September 2026 presents a market where capital values have held better than rental pricing, leaving investors to weigh a rising annual purchase base against softer income.
