A penthouse apartment formerly owned by Sydney conwoman Melissa Caddick is on the market for an estimated $5.5 million.

Liquidators hope the sale will help recover some of the fortune Caddick stole from more than 50 investors, many of whom were her close friends and family.

The apartment was previously occupied by her parents, Ted and Barbara Grimley, and boasts sweeping panoramic views of Sydney’s city skyline and eastern suburbs.

The couple claimed they paid their now-dead daughter almost $1.2 million towards the mortgage on the apartment on the condition they could live in the apartment rent-free until they died.

But the Grimleys agreed to leave the apartment after a long-running court battle in exchange for a reported $950,000 payout from Caddick’s estate.

Listed for auction on October 10, the apartment is located in Eastpoint Tower at Edgecliff, in Sydney’s eastern suburbs.

“Spacious throughout and stylishly presented with understated contemporary finishes, this is the perfect opportunity for downsizers, executives and families who seek undeniable quality and convenience,” an online listing states.

Viewings are by appointment, according to managing agents Richardson and Wrench.

Caddick lived a life of luxury after stealing up to $30 million via a ponzi investment scam.

The 49-year-old disappeared in November 2020, just days after her Sydney eastern suburbs home was raided by ASIC investigators.

A coroner in May ruled Caddick was dead but could not determine the cause.

The fraudster’s badly decomposed right foot, which was still attached to a running shoe, washed up on a beach on the south coast of NSW in February 2021, but the rest of her body has not been found.

Last month, investors received a share of $3 million recouped by liquidators Jones Partners following the sale of Caddick’s share portfolio and Dover Heights cliff-top mansion.

At the time, Jones Partners principal Bruce Gleeson said it was not unusual for investors to receive nothing back from ponzi schemes.

He said the sale of the Edgecliff apartment would allow for further significant distributions to investors.
