How about the act of buying itself? Here where I live, you need to pay 12% on top of the home price simply for taxes and notary service. IMO it's one of the biggest obstacles and why most Swiss people prefer to rent.

Switzerland is a bit different from the US. From what I understand, property ownership entails paying the imputed rental value in taxes, which makes property ownership much less desirable. In the US, mortgage interest is tax deductible up to a certain limit, property taxes are deductible, and there's an amount of capital gains that's excluded from taxation when selling one's primary residence. Compared to other places in the world, the benefits of property ownership are pretty bonkers.

Wow that's quite unreasonable. In the UK it's not the case, there's some amounts to be paid if the property is in higher ranges of price, but there is a tier where that's zero.
