Between Grand-Lancy and Petit-Lancy, the commune has become one of the most dynamic markets in the canton, boosted by the Lancy-Pont-Rouge station and the Léman Express.
Flat prices in Lancy run at CHF 12,000 per m², a level that has stayed in step with Geneva. 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. Geneva publishes what actually sold. In Lancy that comes to 291 completed transactions over 2 years, at a median of CHF 1,210,000 per property in total price. Set that against listing prices and you get a measure of local negotiating room.
Out of 45 communes measured in Geneva, Lancy sits at position 19. The communes immediately above and below are the ones a buyer will actually compare against, far more than the cantonal average. Houses carry a premium of 6 percent per square metre over flats in Lancy, CHF 12,700 against CHF 12,000. Households buying a house here are mostly trading up from a flat nearby, so demand holds even when volumes drop.
The last twelve months added 2.3 percent in Lancy. 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. 159 properties are currently on the market in Lancy. Supply at that level decides how long a sale takes, because the more listings compete, the more the first serious offer sets the reference for the rest. 1919-1945 accounts for 14 percent of homes in Lancy, ahead of the other periods without dominating them. A mixed stock widens the price range inside one commune: two flats of the same size can be a third apart on condition alone.
The average home in Lancy has 3.2 rooms for 82 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. From CHF 3,700 to CHF 9,700 per square metre in 25 years, +162 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.
Knowing the median in Lancy gets you halfway. The second half is what separates your property from that median: condition, orientation, outside space, parking, and the works still to be done.
