Risk: Moderate

Investing in Real Estate ETFs can be a moderately risky side hustle for beginners starting from scratch, especially if they can't afford to lose money. The main risk lies in the potential to lose money invested in the ETFs themselves if the real estate market experiences downturns. While there is potential for gains, beginners could lose both money and time if market conditions are unfavorable. Start-up costs range from $0 to $100, depending on the platform used for investing. It's not uncommon for beginners to invest money and not see immediate returns, especially if market conditions are volatile. Online discussions often mention the importance of thorough research and understanding market trends to mitigate risks of losing money. I'd rate the risk a 2 out of 3 because beginners could potentially lose money invested in Real Estate ETFs, especially if market conditions are unfavorable.
