Timber Slabbing; - Right now I am taking to a 20m3 tree for my floor boards. Resale value of that wood is 40k/50K. But I will keep it for my house I am building.
Aquaculture;
My dam is 1Gig. It returns about 30k per annum.
Avocado production;
Current rate is about 24k profit per acre. Truffles - Returning about 150k per annum on 3 acres.
To me this is much better value than buying a house and waiting 20 years then collecting a piddly bit of rent.
