Adding a Tradeline Before You Shop for a Car

Car buying moves fast. You test-drive on Saturday morning and someone is running your credit by Saturday afternoon. If you want a seasoned account on your report for that moment, it has to be there before you walk onto the lot. A lender works with what your report shows on the day they pull it, and nothing you add the following week changes that deal.

So the order of operations is simple. The tradeline goes first, then the loan quotes, then the car.

According to FICO, most auto lenders pull FICO Auto Scores, an industry-specific version of the FICO Score tailored to predict whether you'll pay an auto loan on time. FICO's industry-specific scores run from 250 to 900, while its base scores run from 300 to 850, so the number a dealer sees may not match the one in your credit app. FICO also notes that a lender may use a different FICO Score than the ones myFICO shows you, or another type of credit score altogether. You can't control which one they pick. You can control what's on the report underneath it.

The basics still apply. FICO says a history of paying as agreed, using available credit wisely and only applying for credit when needed will typically result in a higher FICO Auto Score. A tradeline adds to what those scores read from your report: a seasoned card's age and its credit limit, with the sponsor expected to keep the balance at 15% or less of the limit while you're on.

Pick the weekend you plan to buy, then build the plan in reverse. Give yourself more room than you think you need.

If your file is young, look for age. If you carry card balances, look for limit. Every listing in the catalog shows the bank, the credit limit, the account age in years and months, the Reporting Period and the price, so you can match one to your gap and your buying date in a few minutes. The bank name is what you'll look for on your report once it posts. Not sure whether you need one or several? How Many Tradelines Should You Buy runs the numbers.

Mind the back end as well. You stay on the tradeline for two billing cycles and then you're removed. Shop while it's reporting, not after.

No one can promise you a score or a loan approval, and a tradeline doesn't remove late payments or collections already on your report. Results vary from file to file. It also never makes you responsible for the sponsor's card, and you never get the card or the account number.

What we stand behind is posting. If the tradeline doesn't post to two of the credit bureaus by the end of its Reporting Period, you choose a full refund or an exchange for another tradeline. Claims go by email within 21 days after the Reporting Period ends, so check your reports as soon as the period closes. That leaves time to exchange for another listing before you shop.

Set your shopping date, then open the catalog and order the tradeline that reports before it.
