House flipping at a healthy peak?

[James Rodgers]

This WSJ articles says the amount of houses being flipped is back to the level it was in 2006, but shouldn't come with a great amount of concern. Also, the #1 market for houses flipped in the last quarter was Birmingham, AL and I'm a little bit proud. This is due to the quantity of turnkey flips here, most likely, though we do have a booming retail flip market going as well. 

Thoughts? Is it right to say that we've returned to this percentage of flipped houses being sold, but it is healthy?
