They haven't ever really expressed interest in knowing what the LLC invests in. 

@Brian Eastman, let's have a technical discussion.  1st, I agree with what you and the the posters are telling the OP, though for perhaps a different reason than is being expressed. 

It’s sometimes a bit more expensive, you have to deal with deliveries, etc. but it’s not worth an immediate replacement for those reasons.

There can be no assurance that a state without an express provision on the internal liability shield will be recognized.

You do have to consider the length of the delay, if each delay has been about a month or two then, express the fact these delays are costing you time and money. 

Or am I legally able to shut the unit off from the outside since they expressed the intent to be negligent.. 

I have to echo the same feelings that have been expressed by others in the area.

I heard Craiglist present a very good way to find motivated sellers.Anyone can share a list of expression that I can search by for finding them ?

It is being fully understood that except as specifically set forth herein, Grantor has made no warranties, express or implied pertaining to said property, the condition thereof including but not limited to, matters relating to environmental conditions or hazards on the property"Then later on its says " We are the sole owners of the premises and have good right and title to convey the same in manner aforesaid, and that they are free from every encumbrance, except as aforesaid and WE hereby Warrant and Defend the same against all lawful claims....."

I feel bad they paid for this service and did not get the full service I expressed to them.
