How to identify poorly done flips

[April Hamm]

I'm just starting out building my rental portfolio after recently retiring.  I plan to be adding 3-6 houses a year for the next few years, but nearly everything in my area is a new flip.  I'm not opposed to the flips as I'm not really interested in a fixer, but I know some people in my area who have bought recent flips and have found a lot of mistakes and cut corners.  What's the best way to stay ahead of that and not buy someone's cheaply, poorly done flip?  I know we will get each home inspected after the offer is accepted, but is there anything else we can do or anything else we can look for?
