Situation:
I have outgrown my standard house and wish to upgrade to a delauxe house. I have cycled thru all interior, exterior and container held items with the house. All except two items appear to be non-bound, which is a good thing. Unfortunately the two items in question are very nice and critical for me to keep/secure. I have cycled thru all characters to see if the two items in questin are bound to any of them and -no- they appear not to be. Therefore, I can only conclude that the two items in question were either bound to already deleted characters or to my one remaining but disabled character (who happens to be the owner of the current standard house). (Disabled meaning he is greyed out on the log in screen and I do not have an active slot for him, nor do I particularly want to reactivate him at this point)

So I have several questions:
First an easy one. If I buy another house do I automatically sell/abandon the old house? Or must I first sell/abandon the old one before being allowed to buy a new one?

Second. If I buy a new house will the items in the old house transfer automatically to the new house? If so, then life is good and easy.

Third. If the items do not transfer automaticlaly then I will presume that it is wisest to physically remove and secure all items from the old house within individual characters inventories/vaults. True?

Fourth and the more difficult question. The two items mentioned back at the beginning, that appear to be bound to someone but apparently not a current character. Sooo, the two items are either bound to a deleted character or my one disabled character. No idea what will happen to those items if I sell the house. Will they simply dissappear if they belonged to a deleted character or be reassigned to one of my current characters? or if they belong to the one disabled character will they end up in his inbox only to dissappear as he isnt able to be activiated? How do I keep/secure them?

Finally, The two items are very important to me and I have not seen a way to replace them in Middle Earth or in the Turbine store. Of course there may be a way that I am unaware of. The two items are "Colourful Songbird" and "Pesky Dormouse".

Thanks for taking the time to read this post.
