Anyone going for something like this is go with your eyes wide open. You know from to start what you are facing. Just use your calculator and do your maths... and yes, take into account 'the worst case scenario', that means to do your maths with the lower salary possible.
Take a loan of -120.000 € (few thousands more or less). If you have some funds which you will use to pay a part of your flight training, count on a loan of for example -100.000€. All goes well, flight training done and TR, flying and starting to get a salary. How much you will need to LIVE? If you get a salary of 2000€, half of that is for loan reapayments every months so you get 1000€ to live, for some years. Maybe in 5-7 years you can start to make your own money.
Everybody considering this, do your maths and consider your future.
Bank never losses, people do.
