In some of the more unaffordable areas, I'd say Intrinsic_Value's comment about a house worth 70% of the median is already unaffordable, if not out of reach.
Using the figures from my calculations in a post about the
Demographia report.
- 70% of the median house price: $444,010.
- Interest only mortgage for this: $31,152.91 per annum
- Principle and interest mortgage over 30 years: $34,795.32 per annum
- Net income: $62,000 to $70,000 per annum depending on earnings split
The mortgage costs assume a 10% deposit.
Repayments would cost our Sydneysider family over 40% of their gross income, and the best case is 50% of their net income. That doesn't strike me as being that affordable.
If mortgage rates hit 9.45% (the peak in 2008) then the annual cost would be $40,457.76, or nearly 60% of net household income in the best case.
And there's a broader question as to whether banks would actually lend on those terms. I'd expect not.
I don't know how affordability issues play out in Australia, but in the UK I reckon that the groups affected are the twentysomethings trying to buy their first home, and thirtysomethings looking to upgrade.
The trouble is that politicians tend to be a bit old, and have benefited from property price rises to a greater extent, plus the older generations tend to have most of their assets tied up in bricks and mortar. So the solutions tend to be seeking to keep values stable, and providing financial assistance, be it the First Home Owners Grant or (over here) shared ownership schemes.
(You can tell that there's something deeply wrong when schemes to help buyers in the UK are open to those earning up to twice the median wage.
)
So I can't see politicians trying to move the market downwards. That might change if prices are still high in ten to twenty years time when Generation X and Y are in charge.
