Storage auctions are notoriously unpredictable, so you will never truly know what you will find–until you buy it! You can potentially find anything that anyone has ever owned and thought to store. This covers pretty much any consumer or industrial goods and equipment.
There are two different types of units you will come across: those leased by companies and those leased by individuals. Company storage units generally will only consist of relevant equipment and/or merchandise. A unit leased by an individual, however, can contain anything from a new car to just an old mattress.
Before purchasing a unit you must first weigh what you can see in the unit preview against its profit potential to come up with a reasonable bid. Sounds easy enough, right? Right?
