Dear lawyers!
Thank you for your answer. Of course I do not want to do anything illegal, and that is why I am asking.

Would you please also answer the last question. It was:

2- Assume that I buy an apartment for 100000YTL. If I sell this apartment after 3 years for 140000YTL how much tax I am obliged to pay to turkish goverment?

I have heard that if I sell an apartment after 5 years I don't have to pay any tax for the profit. Is this true?

Thank you in advance.
