7. You chose the longest repayment period possible
It’s quite a good feeling when you manage to obtain a loan. However, it won’t be a clever idea to stretch the repayment period as much as you can. For every additional year, you’ll pay a higher interest rate, and in the end it will be such a huge overpayment.
Just consider wisely what would be an optimal repayment period based on your income. Make sure that the contract will allow you to pay early with reduced interests or flexible installments. This is important because you might change your job or get promoted to a position with a higher salary.
