So here goes…If you have a credit card and you don’t pay it off in full each month, then you are living beyond your means. And if you can’t afford to keep your credit card debts down, then you definitely can’t afford to invest in property. I know it might hurt to read this, especially considering the fact that the majority of Australians carry credit card debt. I once had an investor with an income of $180,000 a year – not poor by any means, but he had a whopping credit card debt of $115,000. This means that if you have $20,000 in credit card limits, your borrowing power could be limited by $100,000.
