Georges,
We lived on bananas for 20 years because we paid top tax bracket with no deductions. We were pretty clueless about deductions then, but have made up for it since we discovered negative gearing. We have quite a few old properties now which still give us good depreciation deductions, and are neutrally geared after tax. We also capitalize margin loan interest on some income producing managed funds. This also gives us good deductions plus some nice cashflow. We are down to zero tax this year and don't feel guilty at all as they got enough tax out of us over those 20 years to last a whole lifetime.
In your situation, apart from putting more into super etc. perhaps you could find a tiny bit of equity for a 5% deposit on a brand new (or almost new) modestly priced IP, which would give you lots of deductions for the next few years.... and it is a buyers market.
One of the banks has a 95% loan which avoids mortgage insurance by having someone eg. parents go guarantor for just 20% of the loan.
Of course, if you are currently living on bananas, this IP would need to be at least neutral after tax to protect your cashflow. A superb way to do this, although requiring a bigger outlay, is to build budget duplexes, giving you more rent to cover holding costs, plus huge depreciation deductions, plus it often gives you some instant equity once completed, which you can borrow against for a deposit on the next project. Of course, in this market due diligence is required, especially being careful not to overcapitalize. If deposit is not very big, then maybe just buy a unit in a reasonable growth area to start, hopefully at a big discount.
We thought about the Macquarie products but could not bear to part with our cashflow to subsidize the interest. Thankfully we had enough equity to borrow against for managed funds plus a margin loan. Depending on our margin loan LVR, we can even draw down funds from that sometimes (like a LOC) to pay interest on the bank loans used to buy the managed funds....so cashflow is preserved. This setup is much more flexible than Macquarie, but must be managed carefully to keep LVRs down. However if we did not have any equity, we would have probably started out with Macquarie.
