At the entrance of the Val d'Hérens above Sion, Vex combines a hillside village with the resort of Thyon-Les Collons.
Vex prices below the Valais median, at CHF 4,500 per m². For a buyer that widens what one budget covers, often by a room or by a plot. For a seller it means the surrounding communes set the ceiling. A gap of 18 percent against Valais means the same budget buys noticeably more surface here. It also means resale leans on demand spilling over from the pricier communes next door, which comes and goes with the cycle. Out of 67 communes measured in Valais, Vex sits at position 57. The communes immediately above and below are the ones a buyer will actually compare against, far more than the cantonal average.
At CHF 6,000 per m² houses outprice flats in Vex by 33 percent. The difference is the plot rather than the build: a house sells with land attached, and where there is little left to build on, the land does the pricing. Up 3.3 percent in a year, Vex has been priced by whoever was willing to pay most for a small number of properties. In a commune with few sales, that is exactly how a median gets moved.
Within the District d'Hérens district, Vex lands 13 percent from the local median. A cantonal average mixes city and countryside, so it flatters some communes and penalises others. The district figure removes most of that distortion. No single period defines Vex, though after 2015 leads with 16 percent. That mix works in a buyer's favour, since you can choose between period character and low running costs without leaving the commune.
Average size in Vex is 89 m² across 3.4 rooms. Compare your own property with that figure before you read any price per square metre: an outsized home rarely sells at the local rate, and a small one often beats it. CHF 4,500 per m² is the working reference for a flat in Vex, 18 percent from Valais. Take it as a starting point: in a commune this size, the spread between the cheapest and the dearest street is often wider than the gap to the canton. Over 25 years the median moved from CHF 3,900 to CHF 8,800 per m², a change of +126 percent. That is the market, not your property: a flat renovated in the meantime followed a different curve entirely.
Enough properties change hands in Vex each year to keep the price data steady. Estimates land in a narrower range here, and a valuation can lean on recent comparable sales instead of falling back on the cantonal average. Before you settle on a price in Vex, get a number that reflects your own property rather than the commune. It takes a few minutes, and it changes what you are able to defend in a negotiation.

Count on roughly CHF 6,000 per m² for a house in Vex. That rate applies to habitable surface, which leaves out the garage, the cellar and any unconverted attic, all of which add value but never at the same rate.
16 percent of homes in Vex date from after 2015. That age band sets the technical agenda for a buyer here, since insulation, heating system and windows are what decide running costs for the next twenty years.
