Sartrouville Property Prices, Rents & Rental Yields

About Sartrouville

Sartrouville in the Yvelines department combines a riverside setting with direct links into the Paris region, making it a practical suburban address with its own local identity. For apartment investors, it sits in a mature market where price trends and rental returns need to be read together.

July 2026 points first to firmer capital values. The average apartment sale price reached €288,250, up 0.4% over the month and 8.9% year on year, while the average price per square metre held near €4,650 after a 0.9% monthly dip. That slight easing in unit pricing does not cancel the broader upward trend, but it does suggest a pause at the margin.

The rental side is steadier. Average rent stayed at €1,100 month on month and was up only 1.3% compared with last year, which leaves less room for immediate income growth than for sale-price appreciation. Against that backdrop, the reported apartment yield of 5.03% captures the current tension well: the market still offers an income return, but rising values are nudging the economics tighter than they were a year ago.

For July, Sartrouville looks like a location where asset values have continued to edge higher, while rents have moved more slowly. That combination keeps the investment case supported, but increasingly dependent on disciplined pricing and a clear view of the yield profile.
