"3 investment properties is like a $900K loan on a investment. ~ for arguments sake" Actually it is no where near that amount at the moment - as I have said I own some of the cheapest properties in Adelaide.
"I wouldnt borrow that much buying 1 single stock of anything." Well that is your choice. The risk for me is very low due to my long term plan, and the fact that they pay for themselves. I am more than comfortable with my portfolio's risk/reward ratio for both my properties and shares.
