Hi Pexus,
can't speak for other countries, but interest rates on mortgages and loans are quite high in turkey - up to 17%. My advice would be to seek alternative finance - for e.g some companies, my own included offer a buy now, move in, pay over 18/24/36 months etc at 0% interest, which is much cheaper than a mortgage in Turkey. As you can start using the property from the moment you pay the deposit, you can start renting it out if you wish, so the rent will go towards the next repayment in the schedule.
rgds,
