Le Pecq Property Prices, Rents & Rental Yields

About Le Pecq

Le Pecq sits on a graceful bend of the Seine in Yvelines, close to Saint-Germain-en-Laye and within easy reach of western Paris. Its riverside setting, established neighbourhoods and commuter-friendly position give it a distinctive residential identity that continues to matter to apartment investors.

September 2026 brings the clearest signal yet: prices are recovering a little, but the annual reset still weighs heavily on capital values. The average apartment sale price stands at €285,000, up 1.8% over the month, while the average m2 price is €3,960, only 0.4% higher month on month. That short-term firmness sits against a much softer yearly picture, with the average sale price down 24.0% and the average m2 price down 15.6% year on year.

For income-focused buyers, the tension is straightforward. Average rent has edged up 2.8% in the month and 3.7% over the year to €1,400, helping support a gross yield of 6.86%. Even so, the gap between a modest monthly rise and a sharp annual price correction suggests that Le Pecq’s apartment market is still adjusting, with rental growth improving returns faster than sale values are recovering.
