All the towns we track: our real property price barometer.
An active and affordable market
The prefecture of the Landes, Mont-de-Marsan is the most affordable market in our barometer: a median €2,124 per m² in the first half of 2026, far less than on the Landes coast. It is also an active market: 135 houses sold from January to June 2026, against 109 a year earlier, with a price per m² up 7.9% year on year. By comparison, houses sold for €2,320 per m² in Dax and €2,549 in Saint-Paul-lès-Dax.
Buyers are mainly families and first-time buyers working locally: public services, hospital, air base, shops. They borrow, compare monthly repayments and look very closely at renovation costs and the energy rating. A house at the right price sells; a house overpriced by 10% stays online.
Situations we often see in Mont-de-Marsan
A 1960s-1980s house in Saint-Médard, Le Peyrouat or Saint-Pierre-du-Mont, to be cleared and sold by several heirs.
Rated F or G, old oil or electric heating: a buyer with a mortgage must be able to price the works. A quote in the file changes everything.
Manor house, airial, outbuildings, sometimes hectares of pine: a property apart, which needs targeted buyers and a well-justified price.
A divisible garden or a plot on the outskirts: the area's zoning plan tells you what is possible before looking for a buyer.
Price, the first lever in Mont-de-Marsan
In a market where buyers have tight budgets, the gap between asking price and real price is paid in months of waiting. Buyers also look up public sales: a listing priced too high is dismissed without a viewing. We start from comparable sales in your neighbourhood to set a defensible price, then work on presentation and the file to achieve it.
For a house to renovate, the right question is not "what is it worth?" but "what is it worth once the works are deducted?". A buyer who understands the cost of works negotiates less than one who imagines it.
