It's time to put your agent to work for you. Have them advocate mentioning that your understanding based on the seller's own words was the chandelier was remaining with the home.
With foreclosures there is a multitude of items that "walk" at various times. This should not be the case however, with short sales. Generally, light fixtures stay with the property unless it is stated otherwise in writing on the listing agreement or purchase agreement. In my opinion, if the light was there when you saw the home and the seller said, "it will stay" then it should be in the home at closing.
Don't leave this to chance. Make sure someone puts in writing that the chandelier will remain with the property. Otherwise indicate you will not close if it is removed or a replacement, or cost of replacement is credited to you. Unfortunately Short sales are a very emotional experience for the former owner especially if they lived there, and although better than a foreclosure; many owners end up in a I don't care attitude. I had a short sale former owner that sold everything he could get his hands on even after the contracts were all completed.
Good Luck and protect yourself.
