I recommend that you go into the TitleMax office and ask to speak with the manager. (There should always be a manager or assistant manager in the office at all times.) Once there, ask them to go over a Voluntary Payback Guide with you.
This is a guide to show you how to pay off the remainder of the balance within a timeframe that is best for you. Example: If you are financing $500 and want to make sure it is paid off within 6 months they can show you EXACTLY what to pay to cover your minimum interest PLUS principal. This makes the payment more like a car payment instead of just rolling it over for another 30 days.
It will show you that if you pay $X amount on your due date that $XX amount is going towards your interest, $XX amount is going towards your principal, and exactly how much you will owe the next month. You are not required to go by the VPG, however, it is a great way to get you "back on track" to getting your title. You pick the length of time, get a print out, and start working your way out.
