Bank Owned House Listed for $20,000?

[Chris Heeren]

This is the novice investor in me but why would a bank give an initial offer of $80,000+ on a house during the court house steps auction and then turn around to sell it on the MLS for $20,000 a month later? Is this common for banks to sell houses lower than the court house auction offer? Are there flags that may cause Banks to sell immediately?
