From all other types of loans available, it might be safe to say that a flexible loan is the best. There is one type that will really work to your advantage. This is where you get to get a loan over a certain interest rate. Yet, you have to pay off the loan at a given time frame. You have the freedom to pay at any time that you want. Thus, if you are given a 6 month time frame, whether you pay on the last month the entire amount, you have nothing to worry about.
