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

About Conflans-Sainte-Honorine

Conflans-Sainte-Honorine sits where the Seine and Oise meet, a river setting closely tied to its inland boating heritage. In the Yvelines department, its waterfront and town centre give the location a distinct identity beyond its proximity to Paris.

In October 2026, the key signal for apartments is a split between purchase prices and rents. The average sale price rose 3.0% from the previous month, while the average rent slipped 0.5%. For an investor assessing a purchase against current rental income, that divergence matters more than either movement on its own: a higher entry price alongside a slightly lower rent can reduce income relative to the amount invested. This is a reading of the latest figures, not a forecast of what any individual apartment will earn.

At €195,530, the average apartment sale price is a reference point, not a substitute for assessing a specific property. The reported yield is 6.6%, so rental income remains part of the investment case, but the monthly divergence calls for care when applying that headline rate to a new purchase. These are market averages rather than a guaranteed outcome: financing, costs and the rent achieved on an individual apartment may change the calculation. In practice, compare any asking price with a realistic rental estimate instead of assuming the latest rise in sale prices will continue. The central question is whether the expected income supports the price actually paid.
