Many investors in Sydney's property market have made a fortune over the years as Australia's biggest city rose to become one of the world's most expensive.
But more cracks are starting to appear in Sydney's property market.
Data from CoreLogic shows that the New South Wales capital city's house value dropped by 0.6 per cent over the past month and dropped 0.4 per cent in a week.
As a result, Sydney's house price growth has decreased to 1.9 per cent over the past year.
Those figures mean 2017 was the weakest calendar year for value growth since 2012, according to CoreLogic.
Sydney property investors weren't the only ones to suffer according to CoreLogic head of research Tim Lawless.
"From a macro perspective, late 2016 marked a peak in the pace of capital gains across Australia with national dwelling values rising at the rolling quarterly pace of 3.7 per cent over the three months to November," Mr Lawless said.
"In 2017 we saw growth rates and transactional activity gradually lose steam, with national month-on-month capital gains slowing to 0 per cent in October and November before turning negative in December."
Melbourne's house prices dropped by 0.1 per cent over the past month but prices in the Victorian capital are still up around 8.4 per cent over the last year, far outpacing Sydney's rate of growth.
The value of houses in Brisbane, Perth, and Adelaide remained flat over the past week, according to CoreLogic.
Data from the Real Estate Institute of New South Wales also demonstrates signs of a slowdown for Sydney's property market.
"Sydney's annual rate of growth is now tracking at just 3.1 per cent, compared to the peak of 17.1 per cent seven months ago," the Institute stated.
"Despite the reversal in growth rates since August 2017, Sydney dwelling values remain 70.8 per cent higher than their cyclical low point in February 2012."
Sydney also continues to see an increase in the number of properties advertised for sale with volumes 26.5 per cent higher than a year ago, the Real Estate Institute of New South Wales stated.
And auction clearance rates fell 60 per cent for the final eight weeks of the year, much lower than a year ago, according to the Institute.
Amid the news of a dwindling real estate market companies affected by property price fluctuations, such as McGrath Ltd (ASX: MEA), Asia Pacific Data Centre Group (ASX: AJD) and LandMark White Limited (ASX: LMW), all saw their share prices drop on Monday.
