In the Rhône plain between Saint-Maurice and Martigny, Evionnaz spreads out at the foot of the Chablais cliffs.
Evionnaz tracks Valais closely, at CHF 5,100 per m² for a flat. Communes in this band are the easiest to value: enough sales to anchor a price, and no local anomaly pulling the figures around. Sitting under the Valais median gives a buyer room, though the discount is rarely free. It usually pays for distance from a station, from the lake, or from a school catchment that people compete over. Out of 67 communes measured in Valais, Evionnaz sits at position 47. The communes immediately above and below are the ones a buyer will actually compare against, far more than the cantonal average.
The last twelve months added 3.7 percent in Evionnaz. Rises of this order usually come from a shortage of listings rather than from a wave of new buyers, and they unwind faster than they build. Against the Saint-Maurice district the gap comes to 0 percent. This is the comparison that carries weight for an estimate: communes in one district share a labour market, a transport network and the same pool of buyers.
No single period defines Evionnaz, though after 2015 leads with 19 percent. That mix works in a buyer's favour, since you can choose between period character and low running costs without leaving the commune. At 3.5 rooms and 98 m² on average, homes in Evionnaz are sized for households rather than single occupants. If you are looking for a studio or a two-room flat, expect a thinner choice and less room to negotiate.
Half the flats sold in Evionnaz went above CHF 5,100 per m² and half below, which puts the commune 7 percent from the Valais median. One exceptional sale barely moves a median, and that is why we use it instead of an average. From CHF 3,900 to CHF 7,700 per square metre in 25 years, +97 percent in all. The path was not a straight line, and the flat or falling stretches inside it are precisely what a long average hides. Evionnaz turns over enough stock to give a reliable read. The practical benefit shows at negotiation, where both sides can point to comparable sales from the same year, which shortens the distance between asking price and signature.
Knowing the median in Evionnaz gets you halfway. The second half is what separates your property from that median: condition, orientation, outside space, parking, and the works still to be done.

The reference is CHF 5,300 per m² in Evionnaz. It averages a small number of sales, since houses change hands far less often than flats, so treat it as a bracket to work inside rather than as a price.
Homes in Evionnaz average 3.5 rooms, with after 2015 the most common construction period at 19 percent. The mix means condition varies a lot from one building to the next, and condition is what pulls two similar flats apart on price.
