If you don’t intend to sell it, remove it.

In preparation for a buyer visit or walkthrough, it is imperative to remove from the business any personal items or assets that are not included in the proposed transaction.    

Even if you have made it clear through previous discussions with the buyer that certain assets will not be included in the sale.  If a buyer sees it at the walkthrough, they will expect it to be there at closing. The easiest way to avoid these misunderstandings is to remove the assets not included in the transaction before the buyer arrives.
