How to Qualify for an Auto Loan
For a $15,000 auto loan, most lenders look for a minimum credit score of 580–620, though scores above 700 unlock the best new-car rates near 5.2%. Your debt-to-income ratio should be below 45%. New car loans typically carry lower rates than used — expect a 2.4% premium for used vehicles with good credit. Dealer financing and bank pre-approval are worth comparing before signing; credit unions often beat both on rate.
