A fixed interest rate means the repayments stay the same for the term of your loan; a variable rate means the repayments will change with a rate change. To choose what suits you best, consider your budget, current interest rates and whether you are able to handle increased repayments with a variable loan.
If you pay out your loan early, is there a fee? Check your terms and conditions as financiers have varying penalties.
Always ask the interest rate being charged and make sure it’s competitive. Also ask what the comparison rate is to understand the full total cost of the loan. It’s easy to focus on the repayment amounts, which might be based on what you can afford. You need to make sure the loan is both affordable and a good deal.
