Rebel Wilson recently listed her Balmain property for sale with an asking price of $2.3million, but the most interesting detail in the sale is her connection to the real estate agent handling the property. 

The Australian actor, 44, has enlisted the expertise of her younger sister Annachi "Anna" Wilson who became a sales agent for Cobden & Hayson real estate earlier this year after previously working as a buyer's agent.

Anna, 32, who is the youngest of Rebel's three siblings, is said to have helped her famous sister transform her previous Birchgrove property which the Pitch Perfect star sold for $9.5million in 2022, reported The Nightly on Monday.  

'While most agents transition from sales to buyer's agents, I've chosen to go in the other direction, making the switch to share my knowledge and help more people,' Anna said on the Cobden & Hayson website.

Anna is said to have secured more than $30million worth of real estate for clients in her previous role as a buyer.

Rebel has listed her long-held Balmain property for sale with an asking price of $2.3million after purchasing it off the plan for $1.88million in 2015.

Tucked away in the heritage listed Lever Brothers soap factory in Sydney, the investment property will go to auction on June 22.

The Hollywood actor hired Cobden & Hayson agents Anna and Matthew Hayson to handle the sale, reported The Daily Telegraph earlier this month. 

Spreading out over two levels, the 'house-like' apartment boasts 130sqm of space with two balconies and a rooftop terrace off the upper level kitchen.

With stunning views of the CBD skyline and Anzac bridge, the cooking space features Carrara quartz stone benchtops and a luxurious breakfast bar.

Two bedrooms and a study space fill out the entry level of the unit, with the master bedroom boasting a sprawling walk-in robe and en suite. 

EV drivers will be thrilled to find a charging station installed in the double security parking garage of the building.  

It comes just a few years after the Pitch Perfect star sold off her Sydney Harbour home for an estimated $9.5million in 2022.

Rebel bought the three-bedroom pad for $3.76million in early 2015, before enlisting architect Paul O'Connor for a 'meticulous renovation'.

She made a staggering profit of $5.74million after owning the house for just seven years, reported Realestate.com.au.

Rebel had listed the home in March 2022 and announced its sale in April, but the sale price and new owners were not revealed until July.

The keys were handed to Nick Smart, the founder of perfume distribution company Agence de Parfum, and his husband Todd Graham, a pet food entrepreneur.

The property was previously owned by the author Peter Carey, who sold it for less than a million dollars in the early '90s when he moved to New York. 

Rebel wrote on Instagram on April 11 that year: 'She's sold. Thank you everyone for your interest in my Sydney house. Great result all round.

'I am going to miss this house so much! But I hope the new buyers love it as much as I have.'
