Of course I was hoping there was something of value in the lock box. I was told the seller had collected everything he wanted and nothing would be removed.... then, the listing agent did remove something and did so without notice.
There are a variety of collectible items with some value inside the house. Nothing huge, but it all adds up.
They have agreed to return the box and all contents that are not of a personal nature before closing. I requested that a broker be present when the box is opened to document the contents. But... they're not even 100% sure that the keys they're bringing includes one that fits the box... in which case it will be returned intact.
