Factors That Affect Your Rate
Your exact rate depends on a few key items. Lenders check your credit score first. Good credit means 720+. They also look at loan amount, term length, and vehicle details like model year and mileage. Shorter terms get lower rates. For example, 36-month loans beat 72-month ones.
California rules help too. No state income tax on loan interest keeps costs down. Local credit unions in areas like 94103 beat national banks. Shop three lenders to compare.
