The strong capital gains evident across the Sydney and Melbourne housing markets have created a significant boost in wealth for home owners who were fortunate enough to own a property through the latest growth cycles.
However, the rate of capital gain has been remarkably lower across other markets with home owners outside of Sydney and Melbourne now seeing far less accrued equity from their housing assets. 
On the flipside, there are also those housing markets where dwelling values have fallen, particularly in areas associated with the mining sector where a larger proportion of properties in these regions are now worth less than their original purchase price.
The wealth effect analysis measures two aspects of wealth accumulation via the housing sector: what proportion of dwellings are now worth double their purchase price and what proportion are worth at least 10% less than their purchase price.
Proportion of properties worth at least double their purchase price Nationally, the proportion of dwellings where the value of the property is at least double the purchase price has slipped over the past decade falling from 45.4% of dwellings in 2007 to 39.1% in 2017.
The slippage is evident across regions outside of Sydney and Melbourne where capital gain conditions have been much softer over the past decade.
The proportion is highest in Sydney, where 48.1% of dwellings are now worth at least double what their owners paid for them; ten years ago the proportion was much lower at 37.2% Melbourne follows close behind with 47.3% of dwellings worth at least twice what their owners paid (up from 38.1% ten years ago).
The remaining capital cities show a much lower proportion of dwellings that are worth at least double their purchase price, ranging from 25.9% of dwellings in Darwin to 37.4% in Hobart.
Across the broad ‘rest of state’ markets outside of the capitals, regional Victoria stands out as showing the highest proportion of properties worth at least double the purchase price at 40.8%, followed by regional Western Australia at 34.8%.
The high proportion of properties worth at least double their purchase price across regional WA may come as a surprise, given the weak performance of the housing market across this region over the past five years, however a decade ago the proportion was substantially higher at 60.8%.
Proportion of properties worth at least 10% less than their purchase price Over the past decade, the proportion of properties valued at less than 10% of their purchase price has risen slightly from 3.2% to 3.4% between 2007 and 2017.
The national figures hide a significant difference between the major regions of the country.
The highest proportion of dwellings worth at least 10% less than their purchase price can be found in regional Western Australia, at 17.8%. Darwin (15.1%), Perth (11.1%) and regional Queensland (11.0%) have also recorded a significant proportion of dwellings where values have slipped more than 10% below the purchase price. 
Ten years ago only, while the mining boom was in its early stages, regional Western Australia and Perth were recording the lowest proportion of dwellings where the value was more than 10% lower than the purchase price.
In 2007 only 1.1% of Perth properties and 2.3% of regional Western Australian properties fit this profile.
The lowest proportion of dwellings with a valuation more than 10% lower than the purchase price can be found in Sydney (0.7%) and Melbourne (2.1%).
Ten years ago, 7.1% of Sydney dwellings recorded a valuation that was more than 10% less than the purchase price, highlighting the effect of strong capital gains post GFC.
Drilling down to the suburb level, it is clear how hard mining towns have been hit.
The Bowen Basin town of Dysart tops the list with 65.7% of dwellings showing a valuation that is at least 10% lower than the purchase price.
Queensland’s Gladstone Central is close behind at 64.2% followed by South Hedland in the Pilbara region of Western Australia at 64.0%.
The good news for many mining regions is that housing market conditions seem to be moving through the bottom of their cycle. 
Transaction numbers are generally rising and advertised stock levels are reducing which should help to promote some value recovery in these regions.
As growth eases across Sydney and, to a lesser extent Melbourne, we may start to see a slow reversal of these trends.
It will be harder to double the value of a property in Sydney and Melbourne after such a sustained period of high capital gains, however markets such as Hobart and Canberra, which have gathered some momentum, are likely to see home owners benefit from improved capital gains that is likely to boost their overall wealth profile.
Similarly, the worst appears to have past across the mining sector, although it is likely to take many years before property values recover to their previous highs in many of these regions.”
