opinions on this sheriff sale

I live in Iowa and would like to bid on a home at sheriff sale. I have bought two in the past using this method. This particular home has a debt listed about $260,000. However in doing some loan research I did find a secondary loan in the amount of $91K. The house comps for about $300,000 and assesses at $288,000. It is in perfect shape. I would like some feedback on what you think the bank with the $91K loan might do. Do you think they will bid it up? I realize each house is different but I would like some feedback. I will of course get a full title search done but would still like feedback here.
