3. Rent - Being a landlord is fabulous. You get rent for the rest of your life on the asset that you have created. This type of income also can grow if your property is good, well maintained. The growing income is a hedge against inflation. If you can earn rent to pay for your living expenses every month, you can be very close to achieving financial freedom!
Unfortunately, it took a while for the real lessons to sink in. I was probably 20 or 21 when I read Rich Dad, Poor Dad the first time, which means I wasn’t exactly sure who I was yet.

Betterment – Betterment was the first robo-advisor to launch, almost ten years ago. They’ve automated the entire investing process, so all you have to do is watch your portfolio of assets grow (over the long run, of course). They do charge a .25% annual fee of your account total, so if you’ve got $100,000 that’s being managed by Betterment, you’ll pay just over $20 per month.

The charge is known as the equity charge and is calculated as the value of equity capital multiplied by the cost of equity or the required rate of return on equity. Given the opportunity cost of equity, a company can have positive net income but negative residual income.
