I turned my side hustle into a $735,000-a-year business & never invested a dollar – follow my tips & you can do it too

The mom-turned-business owner said that she has never invested startup costs into what started as a side hustle.

Instead, she started with the clothing in her closet, then used earnings to restock her inventory.

Her first sale was a dress priced at $36 that sold 11 hours after the posting.

Before Mona knew it, "everything was selling really quickly."

Business went into overdrive two years into Mona's thrifting journey, when her husband had open heart surgery, Business Insider reported.

Then, pressured to be the sole income provider for her family, her earnings went from a few hundred a week up to $1,000 as tried other reselling apps for the first time.

Livestreams proved to be another succesful avenue that spread the word about her business.

With his health recovered, Mona's husband helps her handle the business sales.

Scouring yard sales and retail clearance sections, part of her midas touch requires listing as many items as possible.

Mona discounts around 40% from the market rate of currently hot items.

For vintage items, it is more of a dice roll.

One pair of "flamingos and frogs" pants that she intially thought were "hideous" sold for $100 after she bought them for $1.

While many resellers give up, Mona said she won't be stopped, as it took her 7 years to get to making as much as she does now.

"I love it," she said.

"It's an addiction to me."
