Tidying up your finances before a mortgage application feels like the responsible thing to do, which is why it stings to learn that closing an old credit card can lower your score.
Length of credit history counts. The card you have carried the longest is often the one doing the most work for you, and closing it shortens your record.
Utilization matters more than most people expect. Carrying a balance above roughly 30 percent of your limit pulls a score down even when every payment has been made on time.
Timing is the other piece. Several credit applications in a short window read as risk, so a car loan or store card while you are mortgage shopping works against you.
Scores also update on the lender's reporting cycle rather than instantly, so changes made the week before an application usually land too late to help.
