Ms Parsons said her parents purchased the block with dreams of building their family home.
"They were going to build a house, but then they decided to build a home at the back and two holiday units at the front," Ms Parsons said.
Ms Parsons said her family’s story was woven into the fabric of Mooloolaba's history.
Her grandfather owned the first two ice works factories in Mooloolaba and Maroochydore, serving the local fishing industry that once defined the coastal community.
Growing up in the area during Mooloolaba's transformation from a quiet fishing village, Ms Parsons and her siblings enjoyed an idyllic beachside childhood.
"We lived close to the beach - every afternoon after school we would walk across the road to the beach, or down the other way and swim across the river before the canals were built," she recalled.
"We had a great childhood and life - we just didn't realise it at the time."
Ms Parsons said the property developed its own traditions over the decades, with the same holidaymakers returning year after year.
She said her father, a fisherman, would supply guests with fresh fish, while they would reciprocate with fruit and vegetables - as many had travelled from farming areas.
Now in their 70s, the four siblings have made the difficult decision to sell.
"It's been a tough decision - we have so many great memories here,” she said.
“Lots of our family have been involved in it at the time - lots of grandkids have stayed at the property over the years."
