I'm sorry to say that no bank will give you an unsecured loan of 80,000 Euros in your situation. Even with a guarantor, unsecured loans don't loan that much.
You have very few choices.
- Remortgage your (I presume, mother's) home with all the risks that entails.
- Get a job/ better job and save as much money as possible over the next few years.
- Find a cheaper option - The modular path can be done for 40-50,000 Euros as people above have explained. This doesn't necessarily mean poor training if you go with a good provider.
- Find a sponsored programme like the Aer Lingus cadet programme.
I have chosen options 2 and 3 as they were the most realistic ones for me. Of course, some my see it as not ideal, but you have to do what you have to do.
Also, please don't pay a deposit until you are sure that you have the funding in place to take part in the programme. Every penny counts when you are training; and you shouldn't pay for things, realistically, you will not be able to take part in.
