Ok well this is my first margin loan, so im not really 100% sure on how this works. Basically im setting up with Commsec, but before I actually borrow anything, set out how much interest I want to pre-pay etc... I need to apply for a credit limit or something. Now initially I'll prob want $24,500 loaned out, because thats all I have the equity for at the moment. But in about 2 months time, i'll hope to be borrowing $49,000. I'll be selling my car, getting my tax back etc, so by this time i'll have the equity. What credit limit should I apply for? I have a full-time job etc, if that makes any sort of different in this case.
