I have a mobile home that i am looking to sell, it is situated in a nice caravan park with lake side. I am confused by taxes . Some say I wont have to pay tax and others say I will have to pay as it is likely I will sell for over $300000.
Does anyone have knowledge in this area?

You might have a capital gains tax problem, or maybe you dont. It depends on what it is that you are selling, what you have done with in the past, when you acquired it, how much you paid for it, and million other factors

Best thing you can do is find a decent CA and talk to them about it BEFORE you sell, because if you have a CGT problem you need to figure out how to minimise this BEFORE you sell.

good luck
