At the mouth of the Turtmann valley in the Rhône plain, Turtmann-Unterems, Tourtemagne-Unterems in French, combines a valley-floor village with a wild valley.
Flats in Turtmann-Unterems trade around CHF 3,800 per m², under the cantonal level. Cheaper communes tend to have wider spreads between streets, so a single average tells you less here than it would in a tighter market. Prices below the cantonal level move later and less than the top of the market. In practice a correction in Valais reaches communes like this one with a delay, and so does a recovery. Turtmann-Unterems ranks 66 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.
At CHF 4,000 per m² houses outprice flats in Turtmann-Unterems by 5 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. Flat prices in Turtmann-Unterems are up 4.6 percent over twelve months. One year is a short window: measure it against the longer trajectory before you read it as a change of direction.
Against the Leuk district the gap comes to 16 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. 34 percent of the housing in Turtmann-Unterems dates from before 1919. Older stock buys you volume and detail, and hands you the bill for it: roof, heating and windows come round, and thermal performance is the first thing a valuer marks down.
Average size in Turtmann-Unterems is 103 m² across 3.5 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 3,800 per m² is the working reference for a flat in Turtmann-Unterems, 31 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. From CHF 3,900 to CHF 7,600 per square metre in 25 years, +95 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.
Enough properties change hands in Turtmann-Unterems 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. In Turtmann-Unterems the local price per m² is a floor, not an answer. What your property adds to it, or takes away from it, depends on its condition, its plot and its access to public transport.
