From what I learned so far, B permit holders can buy a house for primary residence. If a B permit holder leaves Switzerland, then I heard that he/she has to sell that primary residence in one year? Can he/she simply keep it without renting? Like for example as a secondary residence in Switzerland while primary residence is abroad (non-EU)?
Besides, I heard that if you acquired the house for less than 5 years, then there's a high capital gain tax (50%) when you sell the property. If there's no capital gain, will there be any other kind of "unusual" tax for selling the house? Where could I find more information on this?
Thanks!
