Sales from Mr Fluffy blocks have cleared $630 million and the remaining 35 homes affected have just six months to join the ACT government's loose-fill asbestos buyback and demolition program.
There are 35 Mr Fluffy houses still standing and the government has intended to clear the remaining properties by August.
Of the 1027 Mr Fluffy blocks 992, or 97 per cent, have been demolished.
Twenty-nine properties are still privately owned but 19 owners are set to participate in the scheme. Nine owners have opted to not take part.
Demolition planning is underway on six of the 35 remaining properties.
The buyback program started in 2014 and is managed by the Asbestos Response Taskforce. The taskforce has sold 947 Mr Fluffy blocks - 932 blocks have settled and contracts have been exchanged on 15 blocks.
The program was set to finish in June 2020 but was extended due to the coronavirus pandemic. Mr Fluffy owners now have until August 17, 2021 to surrender their properties but this could again be extended.
The extension was included as part of the government's COVID-19 public health emergency declaration. This stipulated that the program should finish six months after the declaration was lifted, which is scheduled for February 17, 2021.
Environment, Planning and Sustainable Development Directorate deputy director-general Geoffrey Rutledge said the program was extended due to the market disruption of the pandemic, but he said to surrender prior to the August end date.
"We thought six months was a fair amount of time to settle your affairs and make those decisions that needed to be made following the health emergency," he said.
"What we have seen is the health emergency continue, however, the real estate market itself has almost gone back to normal.
"There is no reason why any of the remaining 35 affected homeowners wouldn't want to organise their affairs any time up until that point and participate in the real estate market."
The territory's Mr Fluffy blocks were first publicly identified in 2015. At the time there were 1022 blocks but this has since grown to 1027.
A feature of the Mr Fluffy block sales has been mass auction events where dozens of properties are auctioned off in a single event but Mr Rutledge said this would not happen again.
"It is literally house by house now," he said.
"As they get demolished, registered and cleaned up they'll go straight onto the market either through the Suburban Land Agency or maybe through a contracted real estate agent."
Blocks in Dickson, Fraser, Mawson and Rivett have recently come onto the market.
It came as Housing ACT bought 31 blocks from the taskforce in September. Most of those were larger blocks and were appropriate for accessible housing.
Mr Rutledge said the blocks were also close to public transport and schools.
