Conflans-Sainte-Honorine Property Prices, Rents & Rental Yields

About Conflans-Sainte-Honorine

Conflans-Sainte-Honorine sits at the meeting point of the Seine and Oise, with a riverfront setting that has long shaped the town’s identity in Yvelines. Its waterways, transport links, and compact urban fabric give the city a distinct place within the wider Paris region.

August 2026 brings the clearest signal yet for apartment investors: values have eased while rental income has only moved modestly. The average sale price stands at €189,950, with the average m2 price at €3,170, both down 3.6% month on month and down 15.6% and 14.2% year on year respectively. That gap points to a softer pricing environment than earlier in the year.

Against that backdrop, rent has held better than sales, even if it is not immune to pressure. The average apartment rent is €900, up 1.7% from last month but down 5.8% compared with a year ago. For investors, the result is a 7.3% yield, which suggests income still supports the asset case, though not without tighter economics than the rental headline alone might imply.

The monthly picture is therefore one of adjustment rather than collapse. Prices are lower, rents are mixed, and the spread between them remains enough to keep Conflans-Sainte-Honorine in view for apartment-focused investment analysis. In August 2026, the key question is not whether the market is moving, but how much further the current repricing will go before yields and values find a new balance.
