Hamish Douglass no longer ranks among Sydney’s billionaire class since stepping down from Magellan in February, but his coffers did well from the property market on Thursday evening when he and his sister Sybella Morris sold their long-held family home in Double Bay.

There had been a $30 million guide for the 2300-square-metre property when it hit the market less than two weeks ago through Ray White Double Bay’s Elliott Placks, and sources have suggested it sold for almost that figure.
