If renting as one 'house with sleepout'.
If separate. Do it on gumtree.
I have a situation like that, the for insurance purposes I rent it as one through an agent.
Hey,
Congrats on your latest purchase.
So some observations:
Seems you missed the $7k council contribution for the GF.
Also how did you get $260/week for a 45m2 granny flat?
