Overview of the Auto Refinance Process
When you refinance a car, a new lender pays off your existing auto loan balance in full. In return, you sign a new promissory note with the new lender, ideally securing a lower interest rate, a shorter term, or lower monthly payments.

Step 1: Gather Required Documentation
Before submitting applications, organize the following documents to streamline approval:
- Current Loan Payoff Statement: 10-day payoff quote from your existing lender including account number and per diem interest rate.
- Vehicle Details: VIN number, current mileage, trim level, and state vehicle registration card.
- Income Verification: Recent pay stubs (last 30 days), W-2s, or bank statements showing steady deposits.
- Proof of Insurance: Full coverage auto insurance declaration page naming the new lender as loss payee.
Step 2: Submit Pre-Qualification & Rate Shopping
Apply for pre-qualification with multiple credit unions and online lenders within a 14-day window. Under credit scoring rules (FICO and VantageScore), multiple auto loan inquiries within a short period are treated as a single inquiry to protect your score.
