CARRYING TOO MANY CARDS
Even folks with high FICO credit scores can have several credit cards, but remember that “type of credit” accounts for 10 percent of a credit score and can throw it off, says Barry Paperno at CreditCards.com. Though having too few cards can also throw off a score, it’s better to have a handful of good cards with reasonable limits that can be paid off easily than have an array of cards where a lingering balance can affect on-time payments and overall credit utilization.
