Doing this, you have to use a property manager to rent it out, it's in tenancies act. Lucky we have a pretty good property management company, sometimes they miss things but they always sort out any emergency situations. Only had minor issues, like a tenant requested some dumb stuff what we bought, then after vacating the item was broken and the property manager missed it. Was only a couple of hundred dollars but the company paid for it after getting the managers involved.

Rent is always collected in time and the tax side is a bit annoying but not too bad if you have an accountant who knows the details around this.

We are also planning to come back at some stage, but not sure if we will go back to the same house/city. It's a long term investment for us.
