Fred,
as it turns out i am, between races, a finance broker.
regarding all lending its the 3C's - capacity to pay, cash and credit rating.

property purchasers:
re income:
low docs and no-doc loans are just about gone now unless you can supply BAS and/or a letter from your accountant
full doc loans will require payslips, group cert or if you are self employed your last 2 years tax returns - company and individual .

your chosen profession doesn't matter too much - this is what you need to provide whether you a are a school teacher or a lion tamer in a Barnum and Bailey circus.

re assets:
cash required is minimum 5% of the purchase price
20% is better.

credit - no black marks

that's it really

Also forget all this wishful thinking about being taxed by the ATO.
It will never happen to 99.9999% of the population.

Some people generally just like to "frown" about its possibility as a thin disguise for their bragging about being successful etc.
