Well, if I have to buy a property in Switzerland, it wouldn't be to make living for ma retirement, but more for not to pay a crazy rent. A property which you rent for 2.2k is easily 1.2k in mortgage, which means if you are a owner, you're making 1k per month and in the top of it, if you play it well, you could lower much more your taxes.

At the end, I pay fewer taxes (I'm not expecting ever to finish paying my property in Switzerland), I pay less rent and I invest more in stocks.
