Acquiring 50 units or more; what makes this difficult?

[Geoffrey Murphy]

BP,

I don't believe this difficult, I believe this is very much doable. However, what makes achieving this goal so difficult for most investors? Seeing that "financial freedom" is the HUGE topic now a days. Why is it that some investors achieve this/ANY GOAL towards financial freedom. (Just using this as a number) 50 units=5,000k a month

What makes this difficult?

-not enough capital?
-inexperience?
-Focus?
-unrealistic planning?

Interested to hear your thoughts BP, I mean REAL ESTATE wise, which I'm sure other people can agree, there are a lot of investors, especially here on BP that makes 5,000k a month look likes crumbs!!
