Jose wants to be sure he maintains a high credit score as he is planning to buy a new car soon. What should he do to ensure his score stays high, allowing him to buy his dream car

He must always pay his credit card debts on time and in full. He must always pay his mortgage before due date and as much as possible pay more than his monthly amortization.

He must also have a healthy bank balance with no history of bouncing checks, falling below maintaining balance, and overdraft fees.
