#6 - Check the neck. What I'm looking for is again any showstopping damage to the neck - cracks / holes or anything like that. Very rare, but easier to sort out in the early stages. Other things to do is check for any twists in the neck - this is a showstopper as they can't easily be fixed. Note that the nut can look a little off centre as there will be more meat below the thicker strings than the thinner strings, so it's perfectly normal.
Necks can display some bow up or down - where the neck is not level along its length - this is relatively easy to fix and will be part of the build process, so don't worry if the neck is showing some bow.
This neck is looking fine, so it's off to the next step.
