this chart says it all, page-3

You are assuming all borrowers are single.

The norm is... household income 1.6 times ave income.

So it works out to be $72,000 p.a per household.


lets assume:

house price is 470k
30% deposit as 70% is the ave LVR

= $329k ave loan amount

Westpac Home Loan product for $329000 with an interest rate of 5.359999999999999% for a term of 30 years....

= $425 week

$1384 week income
less $425 mortgage

$959 left to live on per week.



if we are talking investment.....

repayments I/O
$370 week
ave rent income $400 week.

Return $30 week.

Does that answer your question?
