I found this odd, so I decided to call Cobb County and they advised that a basement can only be rented by one adult with some kind of square footage per person limitation, and I could not wall off the basement door.

Lucky that it was localized to the kitchen and one external wall.10. 

Some inspectors may eyeball the work performed and feel it is sufficient to sign off and yet others will ask you to open up the walls to ensure everything was done to code.

so just make sure you're not excluding properties because you're looking for 'cash flow.' that's not the point of a house hack, the point is to build equity.off market deals - you can go direct to owner or connect with wholesalers and others that surface off market deals. 

You won't know until you open up walls.

Most mold is on the surface and can easily be removed with a bleach solution or one of the many mold treatment products available.

I think they are struggling and throwing spaghetti at a wall hoping something sticks.  

In Mass, that means that all components are double-wall, non-corrosive (fiberglass). 

It is an older home, and would be hard to move walls around to make space without basically taking the whole house apart.
