Mont-de-Marsan Property Prices, Rents & Rental Yields

About Mont-de-Marsan

Mont-de-Marsan, in the Landes department of southwestern France, blends a compact city feel with a strong regional identity shaped by its river setting, public institutions, and easy access to the wider Nouvelle-Aquitaine area. For apartment investors, it is a location where local fundamentals matter more than headlines, and where pricing trends can shift the return equation quickly.

August 2026 brings the clearest signal yet: apartment prices are still climbing, but rental income is moving the other way. The average sale price has reached €153,500, up 3.0% from the previous month and 14.1% over the year, while the average price per square metre stands at €2,720 after a modest monthly dip of 0.9% and a yearly gain of 5.2%. Against that backdrop, the average rent has slipped to €480, down 3.4% month on month and 3.2% year on year.

That tension is visible in the reported yield of 4.74%. It is not weak in absolute terms, but the combination of firmer acquisition costs and softer rents means investors are being asked to pay more for each unit of income than they were earlier in the year. In practical terms, August reinforces a selective reading of the market: value has held up in sales, yet rent growth has not kept pace. For apartment buyers in Mont-de-Marsan, the month points to a market that is still advancing on the price side, while income assumptions require more caution than they did a year ago.
