Uhmm, can't a bank see your salaries? Because in Turkey they want to see your salaries. You enter to www.turkiye.gov.tr and print out your last 12 months salaries with a validation number and then hand it to your bank. Or you ask from your employer, he ask it from Social Security, travels back to you and you hand it to your bank.
Then they check wheter you had missed to pay back your credit (even to another bank, because they share data). And they check wheter if you were rejected by an another bank (because they share data).
Basically, your score is high if your salary is high.
