From what I can make out.
For sales by individuals,after a 5 year period following purchase,no personal tax is charged on the gains attained.So that means at least 5 years of ownership.
If you bought your property before 1st January 2007 the law is 4 years from date from purchase.
So Diana it would depend when you bought your property how long it was before you were able to sell without having charges for Capital Gains.
If you are liable for Capital Gains Tax there is as from 1st January 2010 exemption for the first TL 7,700.
Still doesn't make it clear about how the council tax is divided up though does it!
