A convayencer will be helpful for some of the charges associated with things too.... Like I believe there is a discount on stamp duty or another charge for "primary residence", so if you are selling the place you have and are purchasing a new primary place of residence, you get about $1000 discount.
Some states offer this - I know queensland has a PPR stamp duty rate and an investor rate.

Land is calculated on the investor rate - which is higher - because there is no house on it yet, regardless of whether or not there is a house going to be built on it.

Thats how it works in Queensland anyway.

In tassie everyone is charged a high rate - no matter if its land, PPR or investment purposes.
