I have a HDT with 2 properties. The HDT issued units to me so I can negative gear for those properties. I am thinking of investing in shares with the same HDT. Will this mix things up? Will this cause the HDT not able to distribute the gains from the shares when it sells off the shares? I heard someone said if the HDT issues units to a person, then all the assets are subject to capital gains tax for the person........ Will it be better for me to set up a pure Discretionary Trust to trade shares?
