Signy-Avenex, made up of the villages of Signy and Avenex, borders Nyon between Eysins and Duillier and has grown as a residential edge of the town.
Flats in Signy-Avenex change hands around CHF 9,900 per m², well above what the rest of Vaud pays. The premium is priced into the land more than into the building, which is why two similar houses here can be valued very differently. A gap of 25 percent over the Vaud median is not statistical noise. It measures what buyers accept to pay for the location itself, and it holds through the cycle instead of appearing in one strong year.
Position 70 of 272 in Vaud puts Signy-Avenex 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. Houses carry a premium of 10 percent per square metre over flats in Signy-Avenex, CHF 10,900 against CHF 9,900. Households buying a house here are mostly trading up from a flat nearby, so demand holds even when volumes drop.
Up 2.1 percent in a year, Signy-Avenex 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. Signy-Avenex comes out 6 percent from the Nyon median, measured against communes competing for the same buyers rather than against a whole canton with several markets in it. No single period defines Signy-Avenex, though 1971-1980 leads with 19 percent. That mix works in a buyer's favour, since you can choose between period character and low running costs without leaving the commune.
Average size in Signy-Avenex is 128 m² across 4.2 rooms. Compare your own property with that figure before you read any price per square metre, because an outsized home rarely sells at the local rate and a small one often beats it. Half the flats sold in Signy-Avenex went above CHF 9,900 per m² and half below, which puts the commune 25 percent from the Vaud median. One exceptional sale barely moves a median, and that is why we use it instead of an average.
The 25-year record opens at CHF 3,800 and closes at CHF 9,300, +145 percent apart. Use it to sanity-check an estimate rather than to project forward, since nothing in the series promises the next decade repeats it. Signy-Avenex turns over enough stock to give a reliable read. The practical benefit shows at negotiation, where both sides can point to comparable sales from the same year, which shortens the distance between asking price and signature. In Signy-Avenex the difference between two flats on the same street can run into six figures. Getting your own number, rather than reading the commune median, is what makes that difference visible before you set a price.
