I've seen situations where tenants had a medical problem and lost their job. 

They said they have unpaid medical bills and that wrecked their credit.

They probably wouldn’t say that person going through school to become an accountant, lawyer, or doctor is greedy and they should just be content with what they have rather than spending all of that time in pursuit of those degrees.Most of us who invest in real estate do it as an investment to create wealth.
