You want to buy a car, but your credit isn't particularly great. To get it where it should be, you'll need to do some serious planning a few months before visiting a dealership, so you can maximize your borrowing power and lock in the best possible loan terms. Let's break down the steps you'll need to take to improve your credit through car loan payments here!

Key Takeaways:

  • Pulling credit reports from all three major bureaus is the best way to find out what's dragging your credit score down.
  • Catching up on past-due bills is the fastest way to improve your credit status.
  • Paying down your cards so that lenders know you are a low-risk borrower.

Weeks 1 to 4: Assess What You're Dealing With

Spend your first two weeks tracking down mistakes and getting disputes in motion by pulling your credit reports from Equifax, Experian, and TransUnion. Look at them line by line to find wrong account statuses, duplicate collection accounts, fake late payments, or old debts that should have fallen off by now. Even a wrong address needs to be fixed. When you find an error, contest it immediately. The bureaus have 30 days to research issues, or 45 days if you send in extra paperwork later.

 

During weeks two through four, focus on your credit card utilization, which is roughly 30% of your FICO score. This is the fastest way to change your score because credit card companies report new balances every single billing cycle. While most people say to stay under 30%, you get the real score spikes when you get your balances under 10%. Pay off the cards with the highest utilization percentages first, not the biggest balances.

 

Make sure to time your payments a few days before the statement closing date, because that's when issuers report your data to the bureaus, not your actual payment due date. Call your card companies and ask for a limit increase to help your ratios (but only if it doesn't require a hard credit check). Keep all your paid-off cards open, because closing them shrinks your available credit and spikes utilization.

Weeks 3 to 8: Tackle Delinquencies and Create Positive Credit History

Look at your collections, late payments, and charge-offs. Immediately dispute anything wrong, and verify that paid collections show up as paid. For unpaid collections under three years old, see if the agency will agree to remove the mark if you pay them. If a collection is over five years old, leave it alone so you don't accidentally reset the seven-year clock by making a payment. If you just have a random late payment on a clean account, call the lender and see if they will remove it as a favor. (Sometimes they will!)

 

For charge-offs, you can try to negotiate a settlement or a deletion, but results vary. Bankruptcies and judgments stay on your files for seven to ten years; you can't get them removed if they're accurate, but make sure the details are correct and that they drop off when they're supposed to.

 

While clearing out errors, make sure you are keeping up with your current monthly bills. Payment history dictates over a third of your score, so put everything on autopay for at least the minimum amount so you don't miss a date. You can also get a small credit-builder loan through a credit union, where you pay into a savings account, and they log your on-time history with the bureaus.

 

Another option is having a relative add you as an authorized user on an old card with a low balance so their clean history attaches to your file. If you don't have a card at all, grab a secured card with a small deposit. Put a single streaming app on it, set it to autopay, and let it run.

Weeks 8 to 12: The Last Steps Before Pre-Approval

Keep checking your files over the last few weeks. If a bureau says there's still an error on your report, but you know it isn't, send proof to the creditor who reported it. Also, stop applying for store cards or personal loans right now so you don't pick up extra credit checks.

 

When you get to the last few days of the plan, start shopping for your car loan. Put in applications with your bank, credit union, and some online lenders all within a two-week window so the credit checks count as a single hit. Make sure you get your approved amount, rate, and terms in writing before stepping onto a lot. Walking in with a pre-approval letter gives you some real leverage, since you can challenge the finance manager to beat your rate before you ever let them run your credit.
