The property was sold by Cobden & Hayson, with it expected to have sold well-above the price she paid for it.
This is in actual fact the second Gladesville property Rebel has offloaded, having sold her first one back in January.
The Bridesmaids star sold the property in just nine days, with an asking price of between $750,000 and $800,000.
Rebel had initially asked for $660 per week rent, but was forced to cut it back to $625, before eventually settling on $595, according to a February 2019 report by Realestate.com.au.
Rebel also owns a waterfront home in Sydney's Birchgrove , which she purchased for $3.76million in 2014, and a two-bedroom townhouse in Balmain, which she purchased in 2018 for $1.88million.
