What scares you most about getting started in real estate investment?

[Jonathan Twombly]

I've come a pretty far way in my investment journey, having acquired 400+ units in the last two years.  When I was first delving into this business, I was afraid that I knew nothing, and that I would lose money.  And both of these things were true:  I knew nothing, and I lost a bunch of money at first.  But I stuck with it, now things are paying off, and I am looking to expand my business and grow further.

But, I am very curious:  if you are just thinking about getting started, what are you afraid of?  Is it not knowing what you are doing?  Looking foolish in front of more experienced people?  Being taken advantage of?  Losing money?  Starting something new?  Being your own boss?

I am sure the answer is different for each person, but I would love to know what people are thinking.  Tell me your own story . . .
