Re: Airplane Noise in Genthod, Versoix, Bellevue, and Vernier?
Post 19
In terms of the property market and valuation, I would be skeptical of any claims that properties under the flight path will become "impossible to sell": The Genthod property market hasn't crashed over the last two decades (which is when the growth rate in number of flights really accelerated). Instead, if you check the property market data (available from your bank), you'll find that dozens of houses are bought and sold each year in Genthod, and that their prices generally follow the broader Geneva property market. Under the broader flight path zone (Vernier, Versoix, parts of Chambesy and Meyrin), you'll also find that hundreds of houses are bought and sold each year, with the trajectory of prices following the same growth rate as the broader cantonal average (which means, between c.1-3% p.a growth in house prices in Genthod over the last three years, for example - according to the latest data available from UBS, which is based on data from bureau des statistiques du canton de geneve). It's certainly not un-investable.... Best thing is to ask your bank, especially since the nature of the swiss property market means that banks here will be more cautious than elsewhere (since, as the 'real' owner of your house over the long term, they carry more risk than banks in other countries).
If you browse the Geneva on house price data (https://www.ge.ch/statistique/domaines/05/05_05/tableaux.asp) and ask to speak to the valuation teams at your bank (I had spoken to UBS and Credit Agricole Financements at the time), you'll probably find that the Genthod housing market generally moves inline with the broader cantonal market. The banks will probably tell you that house prices under the flight path are generally 10-20% cheaper than properties of equivalent size/quality in other areas, and that that is already priced into the market. The only impact that i can think of recent rule changes, are for people who own/owned very large plots of land under the flight path: because of the new zoning restrictions, some of those plots won't be able to be built on. For the rest of us, that simply means that the supply of new properties will be capped (which, if anything, is good for existing property owners).
Personally, i'm not worried about declining house prices in Genthod, and the number of transactions with gently rising prices is certainly reassuring. Add to that the new vote capping the number of flights and the long term prospects for electric aircraft (due within a decade?), and I really wouldn't worry too much about an imminent 'crash' in house prices... the flight noise is not new! To create a crash in any asset's value, new information would need to be be digested by prospective buyers/sellers (and unless they decide to flatten Ferney to build a second runway, for example, i can't imagine what 'new' information could possibly create a crash in the local property market).
Nonetheless, you can definitely hear the plane noise, and depending on where you live, it will be more or less bearable. If you look at the official "courbe de bruit" from the office federale de l'aviation, you'll see which streets/areas are considered "alarme": https://www.bazl.admin.ch/dam/bazl/de/dokumente/Politik/Umwelt/Laermbelastungskataster/geneve.pdf.download.pdf/geneve.pdf. Look at the number of big houses with nice big swimming pools under the flight path, and clearly, even being in some of the noisier 'courbes' doesn't seem to stop some people enjoying life here.
The noise has to be balanced with a number of other factors, and don't forget that plenty of houses sit next to motorways or busy/polluting main roads. Genthod is next to the lake after all, next to the train line, and (ahem) close to the airport. For me personally, those things are all really handy.
Hope that helps. I spent a lot of time researching the topic before buying about five years ago, and would be happy to share any insight or resources.
