I am currently thinking of buying an apartment here (it has reasons, not like a trust in any of this crap here).

Unfortunately I cannot find regulations that match each other so I wonder what is actually real. Agency always talk bullshit so I don't trust them either.

So I am trying to figure out the best way to buy an apartment with the least problems at the end.

I heard that I am as a foreigner not be allowed to sell or rent out my apartment... how does that even work? If I move to another city, I am not allowed to sell my apartment?

If this is the rule, I was thinking if I put my name and my wife's name on the apartment, am I allowed to sell it then? Is it even possible to do so, because we are not married in China (but in another country...)

The agents told me I need to pay at least 1 year of social insurance (or tax?) in the province I want to buy a house. I do not want to buy an apartment in the same province I live in, so I want to know if this is true, especially true for foreigners? (I do not pay social insurance [as foreigner you do not have to pay it if you don't want to], but taxes)

Maybe someone has some more information for me. Thanks.
