Go to your bank, ask for a secured credit card. You put in$$$ the limit is $$$ whatever you put in. You are borrowing your own money, but it counts toward your credit, just like a regular card does. and a great way to build. After a year or two, the bank will usually offer to buy it, and offer it as regular credit card.
Not talking about a card you pay $50, $100 for and use it until it's gone. Talking about a secured card, you make payments, plus deposit whatever you want to increase it's limit to whatever you want, whenever you want. Just be sure to make monthly payments on time.
