If you compare the average wage in Turkey to Britain they are a lot lower,even for doctors or teachers the salaries are modest. Medical care is private though so that would mean an amount of capital in the bank would be advisable even if the private health sector in Turkey is cheaper than in Britain.We have residency and are in our fifties so do not qualify for state pension for years. We also just showed bank statements (British)and proof of income to the Muhtar.
Is there a required lump sum? If there is I have never heard any figures mentioned.
