On the sunny hillside above Sion at the gates of Anzère, Arbaz combines a mountain village with a view over the plain.
Flat prices in Arbaz run at CHF 5,500 per m², a level that has stayed in step with Valais. A commune like this one moves with the cantonal cycle rather than against it, so the wider trend is a fair guide for your own estimate. Arbaz ranks 34 out of 67 communes in Valais on flat prices per m². Rankings shift a place or two from one year to the next without anything real changing, so read the band rather than the exact position.
A house in Arbaz is valued around CHF 7,100 per m² against CHF 5,500 for a flat, a gap of 29 percent. Land is what separates the two figures, and the scarcer the building plots, the wider that gap runs. Up 3.8 percent in a year, Arbaz 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.
The district test is the harder one. Arbaz comes out 13 percent from the Sion median, measured against communes competing for the same buyers rather than against a whole canton with several markets in it. No single period defines Arbaz, though after 2015 leads with 20 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 4.1 rooms and 122 m² on average, homes in Arbaz 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.
CHF 5,500 per m² is the working reference for a flat in Arbaz, 0 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 4,100 to CHF 8,300 per m², a change of +102 percent. That is the market, not your property: a flat renovated in the meantime followed a different curve entirely.
Enough properties change hands in Arbaz 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. Arbaz is a market where recent comparable sales exist and mean something. An estimate here has solid ground to stand on, provided it starts from your surface, your floor and the age of your building.
