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

About Seine-Saint-Denis department

Seine-Saint-Denis combines the momentum of Greater Paris with a dense urban fabric, diverse neighbourhoods, and major transport links. For apartment investors, it remains a closely watched department where price moves and rental levels can shift quickly around local regeneration and long-term infrastructure effects.

August 2026 brings the clearest signal: apartment prices are softer, while rents are edging higher. The average sale price now stands at €268,000, with the average m2 price at €4,250, both down 1.4% month over month and 3.9% year over year. That easing has not been matched by rents, which average €1,000 and are up 0.7% on the month, although they are still down 5.0% over the year.

The result is a market with some renewed yield support, but not without pressure on asset values. At 5.64%, the average yield still offers a meaningful income benchmark for apartments, yet the recent annual decline in both sale prices and rents shows that the balance between purchase cost and income is still adjusting. For investors following Seine-Saint-Denis this month, the central question is whether softer pricing is creating room for better entry points, or simply reflecting a slower income backdrop.
