If you want to get a car loan, you also need to have a steady income to pay for the loan, a low debt-to-income ratio, and good credit. As a 19-year-old, you may not have enough credit history for lenders to approve your loan.
The good news is you still have other options. If you have a trusted family member, you could have them become your cosigner. A cosigner acts as a financially responsible party if you default or fail to pay your car loan. Again, this person must have a good income and excellent credit to be accepted as your cosigner. If you’re approved, you may be able to get a lower interest rate based on the cosigner’s credit rather than your own.
