A lot of news on excessive property prices in Turkey (for a very big part driven by oppotunistic investments). This is not good for locals I agree, but stopping people to sell is the tax (capital gains) when payable within 5 years (I think the TAPU is driving). Even if the selling price (as I understand is stable one pays for inflation (ie depreciation of TRY against EUR/USD).
I am a bit unclear what I have to pay when I were to sell, but I have to pay for sure (this is really one main reasons to wait for a number of years to sell).
Really a shame, if the gains (not really) were not to be taxed, I think many properties would come on the market (more affordable and good for many)
