1. What is car loan refinancing?
Car loan refinancing is the process of replacing your current auto loan with a new one, typically at a lower interest rate.
2. Why should I refinance my car loan?
Refinancing can lower your monthly payments, reduce your interest rate, or shorten your loan term.
3. When is the best time to refinance?
The best time is when interest rates drop, or your credit score improves significantly.
4. Will refinancing hurt my credit score?
Initially, refinancing may cause a small dip in your score due to the credit check, but it often balances out quickly.
5. Do I need good credit to refinance?
Better credit usually means better rates, but some lenders also work with fair credit borrowers.

It’s possible but harder. Some lenders may not approve refinancing if you are “upside-down” on your loan.
7. How do I know if refinancing saves money?

8. Is refinancing worth it for a small loan balance?
It may not be, since savings on a small balance are minimal. Always compare before deciding.

Typically, proof of income, vehicle details, loan payoff amount, and ID.
