I think that whole 'it only cost you 4x your income 30 years ago (in 1979) and now it costs 6x' argument doesn't make sense.
These days our financial products are much more advanced, allowing us to buy more with less deposit, more competitive lenders, offset accounts, longer loans, credit card sweeps, etc.
Our technology has increased a great deal more. Cars, applicances, phone calls, travel, basic food and clothing are much less than what they cost 30 years ago. This freed up cash allows for more money towards servicing a housing loan.
When your ability to service increases from say $250pw up to $350pw that creates a multiplier effect on the final house price.
A better comparision would be:
a) after subtracting the costs of other basic necessities, what % of the remaining income was required to be saved and for what period of time for the bare minimum $ amount required to purchase an average house in 1984.
and
b) what % of the ongoing income required (again, after the costs of basic necessities of the day were subtracted) to service this loan.
Compare that to the 2009 values for time and % amounts for that same control 1979 average property, not what consititues an average property today (which is probably something far superior).
I'd say the amounts of time, savings % rate and servicing % rate would be about the same.
My parents bought in outer burbs Langwarren, Vic for $25k in 1978 or so.
Today in 2009 that property would be worth around $300k.
$300k for a new FHB would mean a 90% loan, so
$30k deposit
+ $12k in stamps and costs
LMI of around $3k?
Total cost to purchase $45k
Saving $1.5k per month that would take around 2.5 years of saving. Not really that stressful for a couple earning the 1.5 the average salary between them (say 80k? - pretty generous I would think - ~25% of their yearly salary for 2.5 years).
And I didn't even include the grant, which would reduce it down to only ~1.6 years of saving at the pretty realistic rate of ~25%.
I haven't asked but I'd say it would have taken my parents around 2.5 years of savings too. Plus they had to pay a mortgage broker $1000 just to actually get the loan in the first place! (4% of the house cost! Equivaluent to $12k on $300k!)
Obviously we'll have differing views on 'basic necessities' between the generations and different cultures, but to be a fair comparision they would have to be the same.
