Your debt is excellent, but you need at least 2 more credit cards. With you having only one card, you are too easily exposed to utilization fluctuations. If you want the best rate on a house next year, you need to thicken your credit file. The highest credit scores come from a mix of credit types (credit cards, installment loans), age and responsible use. Get two BANK cards now (NOT store cards like Kohl’s or Sears and shyt) like Citi Double Cash, American Express Blue Everyday, or Chase Sapphire. Use them for the year and pay off before statement close every month and your score will be at mid to high 700s next year guaranteed. If you don’t have late pays, bankruptcies or anything like that, you are a shoe-in for those cards.
