To give yourself a healthy gap, you should budget to be able to afford at least a 2 percent rise in your margin loan rate. This will protect you against sudden changes in interest rates, which could greatly increase your repayments if your loan amount is large.
Because some borrowers only choose to hold their investments for a short period, there is often the option of paying interest only on your margin loan, which means that you can significantly reduce the amount of your repayments, but never repay any principal.
Margin loan rates can also refer to the loan to value ratio (LVR), which dictates the amount of your initial deposit. So for example, an LVR of 75%, on a $10,000 investment will need a 25% deposit, which is $2500.
