Mail, it is then personal property (assuming it was in your mailbox and you had the right to retrieve said mail). 

They have an internal policy that only one, that is ONE, person can retrieve the rolls from the safe even when the safe door is open and the rolls are visible and at arms reach.If that person is off, at lunch, even on vacation for the week, no one can buy stamps.

And because of that you can call her at will and retrieve CMAs.Hmm sounds familiar...

They also had the place under surveillance in case he attempted to break in to retrieve the property.The reward we got paid for a new furnace.

So anything sold before then would not be retrieved with your search, hard to believe that would be 1/3 of the names though.

Now if I can only figure out where to store that info where I can remember where to retrieve it in 20 years or so...    

HOWEVER, (a) many people would rather preserve their checking account "cushion" instead of having it applied to the mortgage where it cannot be "retrieved" if needed later.

Did you think she did this simply trying to keep you from filling it with junk, or that she intended to use it and frequent the property to store/retrieve things?  

Anticipate that she may have personal property that she still wants to retrieve from the property and that issue may cause some discord.
