Does refinancing make you start over?
Because refinancing involves taking out a new loan with new terms, you're essentially starting over from the beginning. However, you don't have to choose a term based on your original loan's term or the remaining repayment period.
What are you doing when you refinance your car?
Refinancing involves replacing an existing loan with a new one, typically through a different lender. Most people will use it to reduce their monthly payments — either by getting a lower rate or extending their loan term. Refinancing is generally a good idea if it allows you to save money on interest.
Does refinancing hurt your credit?
Whenever you refinance a loan, your credit score will decline temporarily, not only because of the hard inquiry on your credit report, but also because you are taking on a new loan and haven't yet proven your ability to repay it.
