Unknown Market Indicators

[Billy Daniel]

So, I just watched The Big Short for about the 20th time and it got me wondering.  Are there indicators out there for the real estate market that very few know about?  I know mortgages are not the same as they were, but is there something else?

My first thought was syndications.  Many of those were bought on adjustable rates that will start coming to the end of their initial term in the next year or two.  On top of that, it seems that a lot of inexperienced operators made the leap and could be in over their heads.

Thoughts? Some other REI sector?
