The key to any lien auction, whether it's from a seized estate or a self-storage facility, is to get the word out. The last thing you want after spending money on an auctioneer is a low turnout. Use Web sites like Craigslist to advertise for free. Make fliers and post them at local flea markets and antique shops. Look for online community message boards, along with the old-fashioned kind in local businesses, coffee shops and bars. If your self-storage facility is in a college town, market the auctions to students. While many bidders are professionals looking to resell the items for profit, students looking to furnish an apartment can also get in on the auction action.
