The top ranking is the "investor" group — those who don't necessarily have an ordinary working wage but "live off the income generated from portfolios of assets through to non-asset owning classes".
It noted that in Sydney, just under 50 per cent of all apartments were owned by investors — and the statistic is often higher in central areas of the city.
The second highest group are those who own their home outright. The third highest are those who hold a mortgage.
The bottom two categories are called "churners" who have no housing assets. The fourth category are renters who don't own any properties or have a mortgage. They can be wage renters or welfare renters.
The homeless sit at the bottom rung of the ladder, with no income from assets, wages or the state.
The researchers largely focused on Sydney, the nation's most expensive capital city for housing, where they found wealth is increasingly denied by those who own property versus those who will forever be priced out of the housing market.
This system is aided by a tax system that rewards people the more houses and units they own.
"While requiring further empirical verification, we believe that our proposed five-point asset-based class scheme will go some way in explaining how the current structural mutation of capital is central to the production of a new social structure of class," the report stated.
"In short, we see our scheme as providing a long-overdue sociological translation of the implications of growing asset-based wealth inequalities."
