I would buy a brazillion dollars
I won't buy anything instead I'd pay my home loan.
Because since i was born until today, my parents never have a home
It would entirely depend on how much of a millionaire I am? if it was just 1 million I would put into my superannuation to generate tax free income to help pay off my Kids houses.
Invest in stocks.
Pay off debt and mortgage for my parents and rest of my family.
I would buy my debt back and pay off my home, cut my credit cards up invest any balance into my retirement so it may snowball with interest
A freaking HOUSE! because I am thinking of running away.
Pay off all bills. Get new house far away from hometown. Get a pool. Pay for my wedding. New Car. The basics.
I would buy a Cottage in the Country for me and my wife,
So we could live our time we have left in peace.
