Sorry - this is a very basic question but I need a starting point & thought of Invested. As background, property is my main field. I have some managed funds margined through St George. I now want to buy some shares & margin them up by 40%. I know what I want to buy, don't want advice, just do it. How do I do this? Do I advise my margin lender to buy xyz share with a 40% margin? Or do I buy the share first & then contact my margin lender? If I have to purchase them myself I was looking at an on line broker facility.
