Rambouillet Property Prices, Rents & Rental Yields

About Rambouillet

Rambouillet, in the Yvelines department, combines a compact town centre with green surroundings and a well-known château setting. That mix gives the city a distinctive suburban identity, where residential life sits close to the wider Paris region without losing its own local character.

September 2026 brings the clearest signal: apartment rents softened sharply, while sale pricing edged higher. The average rent price is €930, down 10.8% month on month and 2.0% lower than a year ago, which points to a weaker rental line in the short term. At the same time, the average sale price reached €249,000, up 0.8% over the month but still 2.0% below last year’s level.

That split is visible in the price per square metre as well, at €4,150, also up 0.8% month on month and down just 0.3% year on year. For investors, the key tension is straightforward: pricing on the sales side has steadied slightly, but rents have moved in the opposite direction, which can pressure income assumptions even as values hold around current levels. The reported yield of 5.36% reflects that balance, offering a useful snapshot of how apartment economics are currently working in Rambouillet.
