Hi Jay,
Just going through all this it looks like you gone deep enough on this topic. Yes for an Aussie investor cash flow is necessary, but I don’t think its common for all, there are people who can go to your way or may be for some portions of there investments can. The only problems can be investing in 100K+ on something which look like gambling though return can fulfil the objective. In my view it should be in group buyer or may be one can go to buy and resale straight way with a 10% + price to get get out of the portion which is not desired or intended to invest on these shovel ready lots. This can be a strategy for making it possible.
thanks,
Ajy
