Seine-Saint-Denis department Property Prices, Rents & Rental Yields

About Seine-Saint-Denis department

Seine-Saint-Denis combines dense urban neighborhoods with strong transport links and a changing residential fabric on the edge of Paris. For apartment investors, it is a department where local price signals can shift quickly, making each monthly update worth close attention.

In July 2026, the clearest signal is a mild rebound in sale values even as rental momentum softens. The average apartment sale price reached €271,900, while the average price per square metre rose to €4,320, up 0.7% and 1.3% month on month respectively. That improvement, however, sits alongside a yield of 5.48%, reminding investors that pricing strength is not yet fully matched by income growth.

The rent side is moving in the opposite direction. Average monthly apartment rent slipped to €990, down 1.0% over the month and 2.8% year on year. Over the same annual period, both the average sale price and the average m2 price were down 3.9%, suggesting that July’s gains are best read as a short-term recovery rather than a clear trend reversal. For now, the market presents a familiar tension: modest capital-price firmness versus softer rental support, with the income case still doing much of the heavy lifting.
