This is why you need a home inspection!
The nightmares come in from homes throughout the U.S. via certified home inspectors who report back on the audacities they find left in the wake of lazy contractors and inept "DIY-ers" in the basements and crawlspaces of homes just like yours!
Seriously though, if you don't already feel the need to have a home inspector check out your future residence and if your bank doesn't require it, maybe these images of lunch-pail junction boxes and support beams made out of 2x4 piles will change your mind.
Have you run into any home inspection nightmares of your own? Do any of your attempts at fixing up your home qualify for the next slideshow?
