Four credit myths worth unlearning

You need to carry a balance to build credit

You do not need to carry a balance at all to keep a solid score. Paying in full each month builds exactly the same payment history and costs you nothing in interest.

You have one credit score

You have several. Scores vary by scoring model and by the kind of lender pulling them, which is why the number you see in an app may not match what a mortgage lender sees.

Everyone starts with perfect credit

Credit is built, not granted. There is no perfect starting score to be lost, which also means a thin file is a different problem from a damaged one, and is fixed differently.

Checking your credit damages it

Soft pulls, including checking your own report and pre-approved offers, do not affect your score at all. Only hard pulls, from actually applying for credit, do.

Closing a card you no longer use helps

It usually does the opposite. Closing an account removes its available credit from your utilization calculation, so the balances you still carry now represent a larger share of a smaller total. If the card is old, you also lose the account age that was quietly helping you.

If a card charges an annual fee you resent, that is a real reason to close it. Tidiness is not.

Paying off a collection removes it from your report

Paying it changes its status to paid or settled. It does not delete the entry, and the entry can legally remain for seven years from the original delinquency. That is still worth doing, because most newer scoring models weigh a zero-balance collection far more lightly than an outstanding one, and some lenders will not approve at all while a balance is open.

What removes an entry is it being inaccurate, unverifiable, or past the reporting window. That is a different process from paying it.
