Credit score

Closed accounts remain on your credit report for at least 7 years, good or bad.  Good accounts probably help your score and are unlikely to hurt your score when they age off.  Closed accounts with bad marks (late payments, etc) will improve your score as they age off, but you won’t be able to remove them yourself until 7 years since the last activity.  Don’t believe credit “repair” companies that promise to remove bad marks.
