Campbell Newman, when at Brisbane City Council, introduced the "parity factor", in relation to rates paid to the Council by Brisbane apartment owners. Until this time, all rates in Brisbane were calculated based on the unimproved value of the land (regardless of the house or buildings on the land). Under the "parity factor", apartment owners are now assessed taxes at a high rate than house owners. In effect, house owners are taxed based on the unimproved value of the land, but for apartment owners, the tax takes into account the improvements on the land. This doubled or tripled the rates for a number of apartment owners.
For houses, if I build a $2 million house on land worth $400,000, and you build a $250,000 house on the block of land next door also worth $400,000, we both pay the same rates in Brisbane. But if you build an apartment building with 8 one-bedroom apartments, then the rates over all for those apartments will be higher than for the $2 million house.
I guess Campbell Newman will be looking at ways to increase taxes if he becomes Premier, and I doubt that he will be friendly to apartment owners.
