Do you have Steve’s book “0 – 130 properties in 3.5 years” at all? If so, and it is the 2009 version (the update), go read chapter 9. It gives a really good writeup of just how and why Steve uses companies and trusts. He tells me too, that the same system works for both resi and comm – but NOT if negative geared. The latter would need a complete rethink.
If you don’t have it, do yourself a favour and just buy it (for less than a night at the movies) – https://www3.propertyinvesting.com/0-130-properties
