Hi the credit union would be the first port of call if you have an account with them. If not try your own bank.
If you havent ever had a loan before the bank may look for a guarantor usually a working parent who is a home owner.
The bank will look at earnings, length in job, length of contract, age, residential status (renting, living with parents) and also a credit check with ICB.
If you are borrowing €8000 say over 36 months you are looking at around €250-260 a month in repayments, easiy affordable on your salary (unless you have massive outgoings).
