Dear lawyers!
1- What is the relation between "Satis bedeli" on a tapu and the real price that has been paid for the property?

If I buy an apartment which the real cost is 100000YTL how much the "satis bedeli should be?

2- If I sell this apartment after 3 years for 140000YTL how much tax I am obliged to pay to turkish goverment?

Thank you in advance
