Garches Property Prices, Rents & Rental Yields

About Garches

Garches, in the western edge of Hauts-de-Seine, sits close to Paris while keeping a distinctly residential feel. Tree-lined streets, established apartment stock, and easy access to the wider Île-de-France network continue to define its appeal for long-term owners and investors alike.

September 2026 brings the clearest signal: apartment rents are rising faster than sale values, but not fast enough to fully offset the pressure on entry costs. The average apartment rent has moved up to €1,400, a monthly increase of 3.7%, while the average sale price has edged to €501,500, up 0.6% over the month. That combination supports a measured yield of 4.31%, but it also suggests that income growth is doing more of the work than price appreciation.

The pricing picture remains mixed rather than directional. The average price per square metre is €6,310, down 0.7% month on month, yet still 2.8% higher than a year ago. Over the same period, the average sale price is up 0.9% year on year, while rent is unchanged from last September. For apartment investors, Garches therefore looks less like a momentum market and more like one where cash flow and purchase discipline matter equally.
