North Bondi house bought in 2019 for $6.3m sold by 30-year-old for $11.235m

North Bondi’s runaway house prices were writ large at an online auction on Thursday night when a house sold for $11.235 million just two years after it last traded new for $6.3 million.

There had been no material improvements made to the six-bedroom residence with a swimming pool on 440 square metres in the less than two years between sales, leaving it to the housing boom to force the value up almost $5 million in that time.

The windfall should be good news for Annabelle Shamir, who at 30 is one of Sydney’s youngest trophy home owners after she purchased the Bellevue Hill mansion of fashion designer-turned-lifestyle blogger Stephanie Conley-Buhre in July for more than $30 million.

Shamir is married to dealmaker Adam Blumenthal, a Liberal fundraiser and co-founder and chairman of both his family-run boutique corporate advisory EverBlu Capital and cannabis company Cresco Pharma.

Following Shamir’s Bellevue Hill purchase she listed her North Bondi home on Murriverie Road with Ray White Double Bay’s Daryl Rosen and Warren Ginsberg, who offered buyers what was considered a bullish $9 million guide.

There were five registered bidders at the online auction and an opening bid of $8.5 million. The second bid was for $9 million, and the offers jumped by lots of $200,000 and $300,000 from there before auctioneer James Keenan brought the hammer down.

The result equates to a capital gain of more than 78 per cent in the less than two years Shamir has owned it, dwarfing North Bondi’s overall house price median rise of 15.4 per cent for the year to July.

Shamir’s purchase in Bellevue Hill in July has also proved a windfall for Conley-Buhre and her husband venture capitalist husband Oscar Buhre.

Conley-Buhre, the daughter of the late aviation pioneer and philanthropist John Conley, purchased the Victoria Road residence for $17.1 million in 2018 from property investor Richard Scheinberg when he upgraded to the nearby Rona estate for $58 million.

Molnar Freeman Architects then undertook a major renovation of the residence before it was sold on the quiet to Shamir.

Conley-Buhre is yet to settle on the sale, but in June exchanged to buy the nearby Alcooringa mansion in Bellevue Hill for about $28.5 million from medico Louis Klein and his wife Claire.
