Montmorency Property Prices, Rents & Rental Yields

About Montmorency

Montmorency, in the Val-d’Oise department north of Paris, combines a leafy residential setting with quick access to the wider Île-de-France economy. Its apartment market reflects that balance: established suburban appeal, steady monthly repricing, and a profile that investors continue to watch closely.

August 2026 brings the clearest signal in rents. The average apartment rent has jumped 27.5% month on month to €1,090, while the average sale price moved up 2.1% to €295,000 and the average price per square metre edged higher by 1.8% to €4,460. That combination points to a market where leasing costs are rising faster than purchase prices, tightening the equation for new investment decisions.

At the same time, the longer trend remains softer on the sales side. The average sale price is down 7.8% year on year, and the average price per square metre is down 10.8%, even with the monthly uptick. For apartment investors, that creates a mixed backdrop: headline valuations remain below last year’s levels, yet monthly rental momentum has strengthened materially. The reported yield of 5.79% shows that the income case is still present, but August’s figures suggest it now depends more on rent growth than on further price compression.
