if the GF costs 100k and the valuation goes up by 80k only, the 20k is lost. So someone with 80% LVR needs 20k+(20% of 80k) = 36k for the GF.
Say someone builds 2 GFs, that is 72k. Interest payable on 128 k loan @ 5.2%= 128 per week. And you get 275*2=550/week. 422 per week positive cash flow. (There will be some other costs, say the depriciation covers it)
For 72k you can buy a 300k house at 80% LVR and buying costs. Interest payable on 240k loan = 240 per week. And you get 400/week. After paying rates you can get less than 100 per week.
Instead of buying a house, provided you already have 2 houses where GFs can be built, if you build the 2 GFs you get 300 extra cash flow per week.
GREAT, isn't it? Not exactly. The house may double in value in 7 or 10 or 15 years. The GFs won't. So it just depends what you are after. CF or CG...
