The capital of Valais, overlooked by its hills of Valère and Tourbillon, Sion holds the deepest property market in the canton between vineyards and the Rhône plain.
The old town, at the foot of the two hills, lines up older buildings and addresses of character, while the Champsec, Vissigen and Platta districts host family housing. Bramois, Uvrier and Pont-de-la-Morge, attached to the town, keep a village life around the cantonal seat.
The presence of the cantonal administration, the hospital and the schools sustains constant year-round demand. Recent flats with a balcony and properties close to the centre sell quickly, at measured prices compared with the Lake Geneva arc.
Over the past 25 years, the price per square metre of a flat in Sion has gone from around CHF 2 900 to CHF 6 900, a change of +138 %. Over the last twelve months, the trend is +6,6 %.
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.
