Can i ask, would I be in control of how much i can pay each month? I would like to pay perhaps half of it up front and then have it paid off before the end of the agreement.
Generally speaking, you can pay as much as you want each month provided you make at least the minimum payment.
Remember these words though: The Big Print Giveth, and the Fine Print Taketh Away. ALWAYS read and understand the fine print. Let the sales person wait while you take your time. If you don't understand it, find someone you trust to explain it to you. Your signature means you read and understood and commits you to everything in the fine print whether you really understood it or not. THAT is what gets people in trouble.
Financing something here or there, especially to build a credit history, is not a bad thing in and of itself when you have the money available. The trouble comes when financing becomes a way of life of getting the shiny toys when you don't have the money in hand.
People get in trouble when they assume everything will remain rosy and just like it is and live payment to payment without planning for disaster. Then the market crashes or they get laid off or they have a medical crisis and then they're screwed.
My point being -- go ahead and finance if you're able to get 0% and have the money in hand. You'll be building credit history and have an escape if something changes.
