Chua learned about credit the hard way. He ruined his score by running up debt in college. He read up on how to fix it, went on internet forums, and eventually got his credit into good shape—then he landed a job at consumer credit firm Credit Karma. Even with all that effort, though, the big reason for his success was simple: He didn’t miss a payment for seven years. He also used at most 5 percent of his credit limit, since scores can be hurt by high “utilization rates.”
SPECIAL NOTE ABOUT COLLECTIONS: Collection agencies will often report debts to the credit bureaus in an attempt to collect from the consumer. This is perfectly legal as defined by the Fair Debt Collection Practices Act. The issue here is that, intentionally or not, collection agencies sometimes report to the credit bureaus using a newer “purge from” date despite the fact that this is not allowed under the Fair Credit Reporting Act. The result of this misreporting is that the collection item will remain on the credit file longer than they should. If that happens, you can dispute the old account.
