It depends. Fixtures, any kind of personal property that is permanently attached to a house (such as drapery rods, built-in bookcases, tacked-down carpeting or a furnace) automatically stay with the house unless specified otherwise in the sales contract. But anything that is not nailed down is negotiable. This most often involves appliances that are not built in (washer, dryer, refrigerator, for example), although some sellers will be interested in negotiating for other items, such as a piano.
