High mortgage debts leave homeowners vulnerable to economic shocks
Research has shown homeowners took on more debt as house prices rose between 2001 and 2012.

A $1,000 increase in house value is associated with a $240 increase in household debt among property owners, research has found.
A study of over a decade鈥檚 worth of household level data suggests Australians are accumulating debt as house prices rise, exposing homeowners to economic shocks.
Researchers from the University鈥檚 used a Household Income and Labour Dynamics in Australia (HILDA) dataset for 2001 to 2012 to explore the relationship between house prices, household debt and the labour market.
The authors of the study found increases in Australian house prices may lead households to refinance an existing mortgage or change the composition of debt already held. Moreover, the responsiveness of household debt to house prices is greater among households with higher levels of indebtedness.
Increasing household debt has widespread implications for the Australian economy, note study authors , and from the University of Sydney, who conducted the research for the Australian Housing and Urban Research Institute (AHURI).
What happens if interest rates rise or house prices fall?聽
鈥淭he take-up of extra mortgage debt among highly leveraged households exposes them to the risk of significant loss if prices fall or if interest rates rise. This is, in turn, poses a systemic risk for the macroeconomy,鈥� said co-author Dr Kadir Atalay.
鈥淎n economic shock may lead to widespread defaults that would cause the shock to spread across markets and threaten the performance of Australia鈥檚 economy.鈥�
How mortgages affect working lives
Australian households are taking on extra debt in response to rising house prices at a higher rate than that found in studies in the United States and the United Kingdom, said Professor Garry Barrett.
Co-author Dr Rebecca Edwards said the data show households also adjust their labour supply in response to higher housing prices.
鈥淲e find that young partnered men and women reduce their hours of work in response to increases in housing wealth, potentially increasing their leisure or time spent on caring activities. Conversely, older single women appear to use the additional housing wealth to retire early,鈥� said Dr Edwards.
