Thank you, oh nagogs on real estate in France, you will run away. The article says:
"In all cases, you are exempt from capital gains tax on any property that you have owned for more than 22 years."
In Russia, this term is 3 years and it does not matter what kind of property you sell, the main one, where you live or the additional one, which you use or not.
It's not over: you are also taxed each time you donate (with exemptions and reductions...). A house passed down from generation to generation will be taxed and re-taxed, in addition to local taxes. But as they say at the WEF: "you will have nothing and you will be happy"
