Repossession auctions. Repossession auctions occur at many different venues because there are many lenders and owners who take the mobile home back to sell to the public. Repossessed auctions that are open to the public must be posted in the public domain. You can often find them with a quick online search or going through the newspaper. You can also contact local banks to see if they hold these auctions along with used car dealers, local police precincts and other local auction sites in your area. Be sure to register for the auction before going because many require this or you won’t be able to participate. Speak with the auction holders to see if there are any other guidelines to bidding on mobile homes, such as having land or a certain amount of money ready.
