Just east of Porrentruy along the Allaine, Alle is one of the larger villages in Ajoie and reads almost as an extension of the town.
Alle tracks Jura closely, at CHF 4,500 per m² for a flat. Communes in this band are the easiest to value, with enough sales to anchor a price and no local anomaly pulling the figures around. 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. Position 15 of 49 in Jura puts Alle among communes with similar price levels and often very different housing stock. Two communes can share a rank and still value the same flat differently once age and condition are taken in.
The 18 percent premium on flats over houses in Alle is unusual and needs reading carefully. It normally means the flats sold recently were new or central, while the houses were older and priced mainly on their land. Flat prices in Alle are up 2.8 percent over twelve months. One year is a short window, so measure it against the longer trajectory before you read it as a change of direction.
Against the Porrentruy district the gap comes to 25 percent. This is the comparison that carries weight for an estimate, because communes in one district share a labour market, a transport network and the same pool of buyers. No single period defines Alle, though before 1919 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.
The average home in Alle has 4.1 rooms for 96 m². That ratio describes the shape of local demand better than the price does. Many small rooms point to family housing, fewer and larger ones to conversions and new build. Half the flats sold in Alle went above CHF 4,500 per m² and half below, which puts the commune 10 percent from the Jura median. One exceptional sale barely moves a median, and that is why we use it instead of an average. From CHF 4,300 to CHF 6,800 per square metre in 25 years, +58 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.
Transaction volume in Alle 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. Alle 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.

Value my property →The median flat in Alle is priced at CHF 4,500 per m². That puts the commune 10 percent from the Jura median, a gap explained in part by the age of the local stock and in part by how little land is left to build on.
Count on roughly CHF 3,800 per m² for a house in Alle. 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.
Homes in Alle average 4.1 rooms, with before 1919 the most common construction period at 16 percent. The mix means condition varies a lot from one building to the next, and condition is what pulls two similar flats apart on price.
