Firstly you need to define your goal(s):

Do you want to:

retire richer?
retire earlier?
supplement your income?
supplement your superannuation?
Diversify your investments to spread risk?
give up your day job?
Buying the right type of property in the right location will help you to achieve your goal. It is important to establish what your goal(s) is at the outset because it will determine which strategy—renovate, develop or buy and hold, you apply.

But why choose to invest in property rather than the other growth asset, shares

There are many good reasons, including:

capital growth
rental income
hedge against inflation
tax benefits
greater degree of control
lower volatility
high demand.
These topics are covered in greater details when we meet face to face.
