Is turnkey investing bad or can it be profitable?

[Glenn Gillen]

So I've done some reading on turnkey property investing (i.e. biggerpockets, google, etc.) and for the most part, people are saying it's a bad investment. However, I really like the concept as I'm someone who doesn't want to make real estate investing a full-time job due to my other commitments. I'm also having analysis paralysis and can't trust my own calculations (fear that I'm missing some variable or not doing the calculations correctly) during the due diligence. I also live in the Bay Area and while there may be some deals here, I don't feel confident enough to fork up the capital here and think it would be better to look elsewhere. 

My question is this: can I develop a respectable portfolio of cash flowing properties through turnkey alone? Also, what is a good cash flow range for a turnkey property?
