Saint-Cyr-l'École Property Prices, Rents & Rental Yields

About Saint-Cyr-l'École

Saint-Cyr-l'École sits in the Yvelines department just west of Paris, combining a suburban setting with strong transport links and a long-standing residential profile. Its apartment market reflects that balance between everyday living space and proximity to the wider Île-de-France economy.

July 2026 brings the clearest signal: prices are holding steady month to month, while rents have moved higher. The average apartment sale price remains at €296,900, and the average price per square metre is unchanged at €4,790. Against that stability, the average rent has climbed 3.1% to €1,020, sharpening the income side of the picture without changing the entry cost.

That tension is what defines the month. On one hand, the city’s average yield stands at 5.88%, which can still support an investment case based on rental return. On the other, the annual trend is softer: the average sale price is down 8.8% year over year, the average rent is down 11.2%, and the average price per square metre is down 9.5%. Together, these figures suggest a market that has reset over the past year, even as July points to short-term rent recovery. For investors focused on apartments in Saint-Cyr-l'École, the question is less about rapid price growth than about whether current yields can offset the weaker year-on-year pricing backdrop.
