Mike:
Welcome.
Here are previous comments on inspection checklists items for pre-purchase inspection:

Reader's Digest condensed version: Examine the frame closely: if frame members are compromised by rust--(don't walk) run away fast!
Frame rust commonly occurs behind the front wheels. Secondly, buy the best car you can afford. A solid project car needing full restoration starts around $12K.
A complete running, driving, steering and braking car usually costs in the very low $20K. Good luck and let us know when you consider a specific car--we're here. John
