well this would be for my first property purchase (live in for 6months for FHOG) and then rent out. The aim would be for the property to appreciate at least 30-50% over a 10 year time frame as if it doesn't then the benefit of having a IO loan would be eroded as the principle is not being paid off.
I haven't done the calcs on the difference in repayments of IO & P&I loans but I imageine they would be quite benefical and if the IO makes the property cashflow positive, then that would need to be taken into consideration
