In the Chablais plain between Saint-Maurice and Monthey, Massongex keeps the traces of its Roman past by the Rhône.
The valley-floor village, on the former Roman site of Tarnaiae, lines up houses, residential districts and business zones along the Rhône. Its position between the two Chablais towns sustains the appeal.
The closeness of Monthey, Saint-Maurice and the motorway and gentle prices draw families and commuters. Villas and recent flats form the heart of an affordable market.
Over the past 25 years, the price per square metre of a flat in Massongex has gone from around CHF 2 600 to CHF 6 200, a change of +138 %. Over the last twelve months, the trend is +3,5 %.
These figures track the local market over time. They point to a trend, they do not replace the valuation of a specific property, which depends on its condition, its floor and its view.
