Car Buying Tips
20/4/10 Rule
Put 20% down, finance for no more than 4 years, and keep total car costs under 10% of gross income.
Check Your Credit First
Your credit score heavily impacts the rate you get. A good score can save thousands over the loan term.
Get Pre-Approved
Pre-approval from a bank or credit union gives you negotiating power at the dealership.
Avoid Long Terms
72 or 84-month loans lower the monthly payment but dramatically increase total interest paid.
