Thanks for the replies

It is zoned 4A Light industrial. We have a shed at the back of the property and rent out the house (its fenced off)  to a tenant.
Under market value was just wishful thinking.  Id be thinking 'cause we rent it out to residential we wouldn't fit the criteria.
Would it be worth loosing the little rent we obtain and could we rent it ourselves as a business thus fitting the criteria.

Im not familar with 'development site' for SMSF

Cheers

P.S Its a tough area to find good legal advice and someone who sees outside the square
