First of all, as your house will switch from being your Principal Private Residence to an investment property, you may face clawback of the stamp duty exemption that you got.
This means you will have to now pay some or all of the earlier stamp duty that you avoided.
Second, you won't recieve TRS anymore, as you no longer occupy the house.
Next, you may deduct the mortgage interest and ongoing expenses from the gross rent received to arrive at the taxable rent.
Example:
950*10 months (assuming 2 months empty) = 9500 gross rent
less 500*12 mortgage interest (estimated) = 6000
less annual maintenance expenses (estimated) = 1000
= 2500 taxable rental income
This is taxed at your marginal rate (0%, 20% or 42%)
You will also pay CGT if you sell the investment property in the future.
