In the case where the merchant has consistently returned after having gone missing once, you're more than likely OK to leave it. In a few hours, the server should do its automatic reset and you'll start getting the debug message when you enter your building. If you enter and the message says that you are in a floorplan that ends in the number 1, and your merchant and all stored items are there, then you can leave your merchant and items in your home.
