Mantes-la-Jolie Property Prices, Rents & Rental Yields

About Mantes-la-Jolie

Mantes-la-Jolie, in the Yvelines department west of Paris, combines a river setting, established neighbourhoods, and direct links into the wider Île-de-France market. For apartment investors, that mix makes it a location to watch closely, especially when monthly pricing shifts begin to reshape the income picture.

August 2026 brings the clearest signal yet: rents are edging up while sale values remain softer, creating a tighter but still workable spread for investors. The average apartment rent now stands at €820, up 2.9% from the previous month and also 2.9% higher than a year ago. That improvement in rental income sits alongside an average sale price of €191,000, which is down 2.1% month on month and 5.7% year on year. In other words, the entry price has eased even as rents have continued to firm.

That tension is also visible in the yield, which stands at 5.62%. For a market where the average m2 price is €3,260, the current balance suggests that apartment returns are being supported more by rental growth than by capital appreciation. The average m2 price is only slightly up 0.4% over the month, yet still down 1.7% over the year, so August points to a market where pricing pressure has not fully disappeared. For investors, the month is less about chasing momentum and more about assessing whether improving rents can offset the softer purchase environment.
