Lisa Black, owner of Moreton Property Collective, has sold a two-bedroom Petrie duplex for $740,000 in just 14 days, navigating threatening messages and a boundary dispute to secure a street record.
Lisa Black from Moreton Property Collective listed the duplex at 2/4 Cherbourg Court on 12 May 2026 — the same day as the federal budget announcement. The timing wasn’t strategic. The seller had found his next property, the retaining wall repair was complete, and the campaign came together in seven days of preparation.
“The seller just did general preparation,” Lisa said. “We steam cleaned the carpets, did a bit of a deep clean. The property was already in excellent condition. The retaining wall was finalised.”
The boundary crisis
During that seven-day window, Lisa discovered the new retaining wall extended beyond the property boundary. The $22,000 structure had been built incorrectly by the landscaper, creating an immediate dispute with the previously friendly neighbour.
“Tensions ran extremely high,” Lisa said. “I got a text message from the neighbour with a mask on his face — he was dressed as Michael Myers saying he’d come to my open homes. I received some colourful language from the landscaper as well.”
The seller, understandably anxious, worried the situation would derail the sale. Lisa worked closely with the neighbour to keep communication open and provide reassurance that the issue would be remedied, while the seller handled discussions with the landscaper. An agreement was reached to repair the wall within two weeks while the campaign continued.
“I had to communicate with the neighbour like my life depended on it,” she said. “He needed reassurance we’d remedy the retaining wall before settlement.”
What buyers noticed
Prospective buyers remained unaware of the boundary drama. They focused on the property’s standout features: a duplex with lock-up garage plus two additional parking spaces, generous backyard, solar panels with battery, and pristine presentation.
“The property was a bit of a unicorn — what buyers want but rarely find,” Lisa said. “We just hit a little bit of turbulence on the way.”
A local couple expecting their first child fell in love with the backyard and the set-and-forget condition. They could see their family growing up there.
The family connection
What nobody else would know: Lisa managed an investment property for the seller’s parents back in the early 2000s when she started her career. Decades later, she secured the listing for their son Lance’s Petrie home.
“It made me really want to deliver an excellent result,” she said. “I took the stress off it for him and exceeded his expectations.”
The result meant Lance was able to take the next step towards owning his own home.
Lance told Lisa she’d be the first person he’d call again — the ultimate measure of trust after navigating threatening messages, boundary disputes, and budget day timing.
Petrie’s position
Petrie sits in Brisbane’s northern growth corridor, with recent infrastructure investment and university expansion driving demand. The Cherbourg Court pocket offers low-maintenance residential housing within walking distance of Petrie Railway Station, appealing to both owner-occupiers and investors seeking proximity to transport and local amenities.
The duplex achieved both a street record and duplex record at $740,000 after 14 days on market, settling on 26 June 2026. For context, Domain estimated the property’s value around $620,000 prior to sale, with the home last trading in 2022 for $360,000.
About the Agent
Lisa Black leads Moreton Property Collective with a focus on people over transactions. She believes much of an agent’s value happens before a property hits the market — through pre-sale preparation, problem-solving, and guidance. Lisa grew up in a market where agents earned their commission after the signboard went up, and that approach still defines her work today.Visit Lisa’s website for more information or call Lisa on 0421591401.
