Don't buy a house. Rent. Put the money you save into shares..
Start with $20,000 in your Account in highly successfull large companies that are near monopolies, they make large increasing profits and pay good increasing dividends and have a good future ahead of them.
Westfield, Fosters, Brambles etc.
Diversify, and avoid selling if you can purely for tax reasons, let what you owe in tax compound for you not the government.
Each year you buy $20,000 (+ $1,000 for each year) worth of shares . So on the 10th year you are adding $30,000 etc.
After 1 year you should have $20,000 + $21,000 +$2,400 = $43,400.
After 2 years you should have $70,608.
After 30 years you should have $7.4 Million.
Then move to Bermuda....
If you wanna tinker try and pick house price spikes before they happen - or if you can postively gear some investment properties go for it. I'm not against property but by using this method you will be alot wealthier than a property investor without all the effort.
