Sydney residential price growth will slow, but not go backwards: John McGrath

Sydney has between 10%-20% growth left in the upward residential cycle over the next few years, according to estate agent John McGrath.

"Periods of ups and downs are to be expected, particularly after a big surge in prices, so next year we might see some months where median prices rise and fall," he said.

"Prices could be fuelled by share market fluctuations, economic factors and interest rate movements."

McGrath tipped after "incredible" price growth in Sydney in 2013 and 2014, he was "expecting the market to slow down in 2015 but not go backwards".

He affirmed his high hopes for the Brisbane market in the Switzer blog.
