The Swiss tax system benefits people taking a mortgage on their house. When you own a house you have to pay taxes around what you would pay to rent the house. So when you don't have a mortgage on the house you pay twice. Once the "rent" plus the normal property tax. The smart thing to do is to get a mortgage, so you don't have to pay the property tax. The interest to pay will be far less than the property tax.
