18. Invest In Real Estate

Now, becoming a landlord can be daunting – and spending the amount of money required to become one isn’t an option for everyone – but, if you think you have what it takes, it’s a great way to earn good money as a side business.

Companies like Roofstock (look them up!) are making the process of investing in real estate much more simple than you might think – they help you crunch all the numbers, including potential cash flow, and guarantee you’ll have a tenant in the property within 45 days or they will cover 90% of the mortgage payment – and if you’re not interested in becoming a landlord, but think real estate investment is for you, do it through companies like DiversyFund, who give you access to commercial real estate for as little as $500.
