The Melbourne buyers' advocate David Morrell says he is finding it "incredibly hard to buy because you cannot justify the prices."
He said most reserves were being passed easily.
"Are we in a bubble? Of course we are. It just depends who is caught with the parcel," he said.
"But in my opinion, it is incredibly hard to buy because you cannot justify the prices," he suggested in his regular Monday auction roundup in the Australian Financial Review.
He recently blogged "the really bubbling bubble" is at $1 million to $5 million.
He pointed the finger at a June $4.66 million Armadale sale (photo below) at 39 Lambeth Avenue — "a street where anything starting with a $4 would be hard to justify."
Only a month ago Morrell wasn't calling it a bubble.
"Our suspicion is that this isn’t a bubble, it’s a jumping castle.
"Frenetic leaps until it springs a leak and then a slow deflate."
But another Melbourne buyers' agent Mal James continues finding homes for clients, noting while typically at well above agent estimates, they have been rarely above his own price appraisals.
