What you are supposed to do is cut a small hole in the ceiling and go up with a flash light to find the leak.

Meet the inspector with your camera and a flashlight.  

If the problem (for example a water leak) is not immediately identifiable you ( or contractor) can cut a square hole in the drywall, take a look up there using a flash light to locate the problem, then once it is fixed, patch it up, paint over it and it will be good as new.

Poke around with a screw driver , look in the basement or crawlspace with a good flashlight , look for more .

Having a clip board and a flashlight with you and a stack of business cards.

Invest in a good flashlight, take notes when visiting the property.

The inspector for our primary home didnt say anything about the ducts (he just looked throigh the attic opening with a flashlight).

@Erik Mogan congrats on the moves that you have made to a brighter financial future.

I think your listing looks good, but could be improved if you hired someone to take professional photos of the place to make the rooms look a little brighter/larger.

Before BP and people like you, I felt l like I was  in a dark room with tiny flash light, able to  reveal  a little bit of information  at a time.
