"I was often left home alone while my mum worked long hours to pay the bills and keep food on the table," Condy told Jam Press.
"She tried so hard and loved us so much, but things were really difficult back then.
"When my mother lost her job, we were asked to leave the house with a 12-hour notice and had to sleep outside.
"We had to use public bathrooms daily and eventually started jumping between different friends' homes.
"At that time I was scared and lost; this is where my drive comes from because I never want to have anyone in my life be in that position ever again
The difficult childhood gave Condy a strong work ethic.
Determined to protect his family from future struggles, the entrepreneur got his first job at 16, as a dishwasher.
By 21, he had worked his way up to cleaning yachts for the rich and famous.
Condy was so inspired by the lives he saw that he set out to create the same for himself and just five years later, he had.
The young man is now a millionaire with a Lamborghini and designer clothes, who takes regular luxurious holidays – and he did it all by starting an Instagram marketing company, called Branden Condy LLC.
This involves increasing Instagram followers through celebrity giveaways.
"When I was younger, I saved up all the money I earned and began to work on growing my Instagram following," he said.
"I read a book that told me to get me exposure and attention, and so I thought that focusing on social media would do just that.
"But I also followed different entrepreneurs who had the lifestyle I wanted and reached out to them to find out how to get there myself.
"That's how I met my new business partners. I started talking to some guys in Arizona who ran a successful Instagram marketing business.
"After a few conversations online, they invited me to visit them. We met up and I loved everything about what they were doing.
"I saw the cars, the money, the success and wanted to be in their shoes.
"Before leaving, I said that they'd see me back there in 30 days, as I planned to return and start my own business.
"They didn't believe me, until on Christmas Day I quit my job and drove across the country to start a new marketing company with them.
"They became my mentors for a while."
Fast-forward two years and Branden is now a multi-millionaire with an impressive 238,000 followers on his Instagram – making $25,000 profit every month.
But the entrepreneur is determined never to forget where he came from.
"A lot of people just seem out for cash and recognition. If they fail, they have family and friends who'd bail them out in a heartbeat.
"My rise comes from a somewhat different place and though I almost hate to admit it, a lot of it is fear that my future will look a whole lot like my past.
Condy's top tip is to network, as good contacts could help you a long way, but books such as Rich Dad Poor Dad have also helped the entrepreneur get to the next level in marketing.
He added: "Fully believe in yourself and always take that risk because trust me I have lived it and it is worth it. Bet on yourself!"
To thank his family for everything they did for him, Condy is now in the process of buying his mum a house.
"She deserves it, I am so grateful for her."
