If the place is unoccupied there is a good chance that a window or door is open.

It will at least open the door for negotiations to begin.I appreciate your help Joel.

I submitted the email with picture of it taped to his door as evidence.

(non working outlets, automatic garage door openers, toilets that take an extra flush, closet doors that come off the track ect, fireplace not working...)

The other half is on the lot next door and is not included...

The bank didn't shut the door, just said "Let's see where the appraisal for the LOC comes in on your primary residence."

They wind up being either unusable space or just storage since today people want a door on a bedroom and dont want a walk through bedroom for lack of privacy.

Sounds like an encroachment that should have been caught when the house was built, look up adverse possession, you may not be due much if anything.I suggest you take what they give you as it doesn't sound like you have much of a financial loss if your home is far enough away to be marketable, I assume you bought the house with the house next door.

Demand they do or allow you to or2.

Having the credit check in place and screening out poorest credit buyers helps too but if they could get a conventional loan they might not be knocking on your door for a deal anyways.
