You've probably already found something, but yes it's always possible to go inside the house before your bidding. You can go in with a contractor or home inspector usually prior to everyone else seeing the home. Amnet realty in Auburn Maine (talk to Janet, she's great) has a huge list of foreclosures, and williams, and williams auction company does auctions nation wide and they are online. There are tons of other realators and auction companies out there but I have had good luck with both of these.
Good Luck, make sure to get home inspections, and title insurance on any property purchased this way!
