Sydney's price decline continues into 2018

Adelaide has overtaken Sydney as the mainland capital with the second strongest growth in property values.

Sydney house values are down 0.2 percent in the quiet first two weeks of the new year, Corelogic data shows.

There was no movement for the other major markets, Melbourne, Brisbane and Adelaide in the year to date.

Perth was also down 0.2 percent.

Sydney's annualised growth sits at 2.5 percent.

The last time Sydney posted such a low level of growth was at the start of the boom in mid-2012.

There was a 70.8 per cent rise since 2012, Corelogic says.

Adelaide's annualised growth sits at 2.7 percent.

Melbourne is still the market leader.

In December Sydney house prices fell 0.5 percent.

The start of the year is always quiet, but last January (below) saw Sydney prices sitting at an annualised 15.6 percent growth, with 0.7 percent growth just in January, according to CoreLogic.
