I did consulted a local migration agent this Monday. He has suggested this strategy to go for subclass 103 first. In the meantime, bring parents in & lodge subclass 804. He said that he can request for fee adjustment between the visa subclass changes later but can't guarantee. So fee is a risk. By the time parents have time to decide to wind-up early or lease or loose the business (whatever). Isn't one in hand better than two in bush?
Also, we are not looking into pension aspect or hopeful to get it at any stage. Basically because Australia seems to be a sinking ship (constant rising unemployment, commodities crashing, widespread corporate greed, small businesses closing, commercial vacancy rising, banks monopoly ... & so on). We want them closer, i will get build granny for them in my huge backyard.
Any other likely strategy, please let us know.
Thanks for your contributions.
