Lajoux and Fornet-Dessus lie on the eastern side of the Franches-Montagnes, on the high plateau of wooded pastures towards the Bernese Jura.
At CHF 4,400 per m², Lajoux sits near the middle of the Jura scale. Which side of that median your own flat lands on depends more on floor, view and condition than on the address itself. The premium over Jura has a practical effect at resale. Buyers arriving from cheaper communes negotiate hard on condition, because they are already stretched on the price per square metre before they walk in.
Lajoux ranks 18 out of 49 communes in Jura 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. Flats in Lajoux cost more per square metre than houses, CHF 4,400 against CHF 3,900. That points to a compact, well-served centre where small units are in demand, while the houses that sold sit further out on larger plots.
The last twelve months added 4.2 percent in Lajoux. 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. Within the District des Franches-Montagnes district, Lajoux lands 4 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 Lajoux, though before 1919 leads with 23 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 4.4 rooms and 117 m² on average, homes in Lajoux 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. The median flat in Lajoux comes out at CHF 4,400 per m², a gap of 7 percent against the Jura median. That figure covers every flat sold, whatever the floor, the age of the building or the state of the kitchen.
Over 7 years the median moved from CHF 5,200 to CHF 6,100 per m², a change of +17 percent. That is the market, not your property. A flat renovated in the meantime followed a different curve entirely. Transaction volume in Lajoux is high enough that one unusual sale does not distort the medians. That matters, because thin markets are where automated estimates go furthest wrong and where a local opinion earns its keep. If you are weighing a sale in Lajoux, the useful question is not the commune price but yours. A few minutes and a handful of characteristics are enough to place your property inside the local range.
