A three-bedroom house in Glen Waverley sold for what is believed to be a Monash record of $6 million at auction on Saturday.

On about 1538 square metres, the knock-down at 17 Marriott Parade is located in the sought-after Glen Waverley Secondary College zone and was advertised as a “great opportunity for a four-storey apartment complex”.

Documents from the Victorian land titles office show the property last sold for $4.71 million on June 19, 2015, to Marriott Pty Ltd, with Fen Gao listed as the director.

This represents a $1.29 million windfall for the vendor in just over two months, which equates to a $20,156 gain every day, or $839.80 every hour, or $14 every minute for the past two months.

Barry Plant auctioneer Sam Rossello believed it was a record for a residential property in Monash.

He suspected the previous Monash record was also set by his company, who sold a house on Lum Road in Wheelers Hill for about $5.1 million more than two years ago.

He said more than eight parties expressed an interest in bidding on the day, but only four participated. The buyer was an investor who didn’t know what they would do with the property.

“All the activity that has been happening around Glen Waverley has been unbelievable,” he said. “Recently The Glen announced a $500 million upgrade, which is going to bring 2500 jobs to the area.

“There’s been a lot of people [developing] multi-storey apartments.”

The agency had been quoting more than $4.5 million for the property.
