Personally, I would probably look to use the target property as security, just as a protection means, but that doesn't dilute your valid point (as I interpreted) that you still need other security of your own (property or shares/funds) to finance the loan to the super fund (unless you have cash, of course).
I'l be keen to hear what comes out of the SPAA love-in. I'm not going as our business is too young and can't afford it. Besides, not much in the agenda excited me, to be honest.
Cheers
P.S. - waiting for a reply to my email to SA stamps office
