A small village in the left bank countryside, Gy offers a preserved rural setting on the doorstep of France.
At CHF 12,200 per m², Gy sits near the middle of the Geneva scale. Which side of that median your own flat lands on depends more on floor, view and condition than on the address itself. Geneva publishes what actually sold. In Gy that comes to 32 completed transactions over 2 years, at a median of CHF 1,390,000 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, Gy sits at position 18. The communes immediately above and below are the ones a buyer will actually compare against, far more than the cantonal average. Flat prices in Gy are up 3.5 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.
No single period defines Gy, 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. At 4.3 rooms and 133 m² on average, homes in Gy 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. From CHF 3,900 to CHF 9,300 per square metre in 25 years, +138 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.
Gy 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 →Around CHF 12,200 per m² for a flat, which is 3 percent from the Geneva median. Houses are priced separately and usually land somewhere else entirely, so work from the figure that matches your property type.
Count on roughly CHF 12,100 per m² for a house in Gy. 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.
16 percent of homes in Gy date from before 1919. That age band sets the technical agenda for a buyer here, since insulation, heating system and windows are what decide running costs for the next twenty years.
