I like to pay it as soon as it shows up on my transactionsIf you have a Netflix or TV subscriptions use your credit card to pay for them. Then pay it off before the 30th of each month and just keep doing it for about a year if possible. That'll establish to creditors that you have a solid credit history.
Also buy gas on your card as well but just remember to pay the card off before the new cycle starts. It'll will help you out then just rinse and repeat.
I was gonna use cash anyway so at least lemme get this lil perk first
