How do you invest in REITs? Are they safe? Pros and cons? Where to find the best?

[Account Closed]

I'm thinking about investing in REITs, and from the little that I have heard, they sound too good to be true.  Guaranteed returns, nothing to manage, etc...  On the surface, they seem like a good way to create annual cash flow.

For those who invest in REITs, how do you go about discerning which ones are good and which ones are not?  

How does one get started in this type of investment?  Where do you find them?

Thanks!
