Check list for the rehab part of flipping?

[Michael Plante]

Flipped my first place 30 years ago in Medina NY. 

Have done a few more since then

Have 4 more I am about to do.  I think I can do the rehab part much more efficiently.  

Definitely not overly organized and am willing to learn a better way of doing all this 

Anyone have a list of what to do first next etc?  Like Roof, exterior walls, inside demo etc etc
