Property prices in Australian capital cities increased by 0.8% in July, a new record high, with values now 6.3% higher than the first seven months of the year, the latest published data shows.

However, while overall values are still rising, four of Australia’s eight capital cities recorded a fall in dwelling values over the month, the CoreLogic July home value index also shows.

Simultaneously, the rate of growth across the combined capitals aggregate index slipped back a notch after bouncing higher in April and May.

The annual rate of growth, which hit a recent peak at 11.1% across the combined capitals index in October last year, is now tracking at 6.1%, the slowest annual rate of appreciation since September 2013.

Sydney and Melbourne have also seen the annual rate of growth slip back to below 10% with the July indices showing a respective 9.1% and 7.5% capital gain over the past 12 months.

Previously both Sydney and Melbourne’s capital gains peaked higher with Sydney reaching a peak rate of annual growth in July last year when dwelling values were rising by 18.4% annum and when Melbourne values were increasing by 14.2% per annum over the 12 months ending September last year.

Darwin and Perth remain as the only two capital cities to record a negative movement in dwelling values over the past year with prices in Darwin down 7.6% and Perth values falling by 5.6%.

July marks the 50th month of the combined capitals growth cycle, which commenced in June 2012. Over the cycle to date, capital city dwelling values have risen by 38.3% and according to CoreLogic head of research Tim Lawless this demonstrates the strength in the Sydney and Melbourne growth trend with dwelling values across the two largest capitals recording a cumulative 61.3% and 42% over the cycle to date.

Hobart, where the growth trend has recently accelerated, has been the next best performer with values rising 17.6% over the growth cycle followed by Brisbane at 17.4%, Adelaide at 14.3% and Canberra at 12.4%.

‘The recent moderation in the rate of capital gains should be viewed as a positive sign that growth in dwelling values may be returning to more sustainable levels. However, the growth trend rate is still tracking considerably faster than income growth resulting in a deterioration of housing affordability,’ said Lawless.

‘Using Sydney as a case in point, the Australian National University estimates that Sydney household incomes have grown by approximately 4.5% per annum since June 2012 while dwelling values are up 12.1% per annum,’ he added.
