Once the auction for a unit starts, the door to the unit is opened and potential bidders are allowed to view the contents only by looking in from the doorway; they may not step inside, touch, or move any of the contents prior to the auction. Generally, the spaces and their contents are sold "as is, where is" with no warranties or guarantees implied or provided, and the terms of sale are cash-only upon conclusion of the auction. The purchaser of a unit takes possession of its entire contents and is responsible for removing them within a set period of time.
