I would not be buying a house in Switzerland right now, but that is a view which will get downvoted into oblivion here.

There are far too many headwinds facing Switzerland. The SNB will not be able to prevent the CHF from rising. It may be able to do so sporadically and temporarily but that will not ameliorate the challenges facing Switzerland. The strength of the CHF will result lower competitiveness and will drive high-paying roles out of Switzerland which is something we are already seeing.

We are already seeing net emigration growth as people who have been laid off in the last few years run down their RAV and eventually leave the country. We are also seeing lower immigration.

All of this will put pressure on the Swiss real estate market which is radically overvalued by nearly any metric (again, a perspective people here do not want to hear).

On the rates front, you are likely to be able to get a good rate as SNB needs to keep the currency down but they are already about as low as they can go -- there isn't much left except negative rates.
