Sartrouville Property Prices, Rents & Rental Yields

About Sartrouville

Sartrouville in Yvelines sits on the northwest edge of Greater Paris, combining riverfront stretches, residential neighborhoods, and strong transport links with the wider metropolitan area. Its apartment market is shaped by that commuter-adjacent setting, where everyday housing needs meet a steady investment lens.

August 2026 brings the clearest signal for Sartrouville apartments: prices are holding a firmer line than rents. The average sale price stands at €286,000, while the average m2 price is €4,610, both down 0.8% over the month but still pointing to a market that has moved higher over time. Year on year, the average sale price is up 10.4% and the average m2 price is up 5.1%, which keeps the pricing trend intact even after this latest pause.

That rise in capital values comes against softer rental momentum. Average rent is €1,090, down 1.4% month over month and also down 1.4% year over year. For investors, that creates the month’s main tension: stronger sale prices alongside weaker rental progression. The result is a yield of 5.06%, which still leaves room for income-focused analysis, but not without acknowledging that rental growth has not kept pace with the lift in apartment values. In practical terms, August looks less like a breakout month and more like a market digesting earlier gains while income returns stay comparatively restrained.
