Malcolm Turnbull has had an offer for his "very lightly lived in" Kingston Foreshore, ACT penthouse.
The Eastlake Parade apartment had been listed by Berkely Residential on AllHomes last September.
It was tipped to fetch at least $2.5 million, but reported to have been sold for $2 million.
The Turnbulls bought the apartment off the plan for about $1.95 million in 2006.
Turnbull spent his first four months as prime minister there before moving into The Lodge in January 2016 after renovations.
The two-level, three-bedroom penthouse features marble bathrooms, a huge terrace with a covered outdoor kitchen, in-slab heating and polished hardwood floors.
It is described as a "very lightly lived in" with the "most sensational views over Lake Burley Griffin, East Basin and the city".
