What are the pros and cons of 1031 exchanging into a DST?

[Jack B.]

I like the idea of no longer having to be hands on with tenants and toilets. But what are the risks and the cons?

I see a lot of nomenclature from companies about estimated 7 or 11% return for their DST, plus you'd get appreciation, etc. But

1) What is the typical total return on a DST?

2) How long is the money tied up? 

3) What are the risks? 

4) How do I screen DST's?

While I would like to get out of dealing with tenants and toilets, I don't want to throw the baby out with the bathwater...
