Buying a foreclosure quadplex

[Clark Spruill]

Hi everyone, I'm fairly new to this and I have a question (and probably many follow ups.) I've found this quadplex that has a notice of sale posted for it and it's going to auction next month...but it looks like the owners are trying to sell before that happens. From a quick glance it looks like they're trying to sell it about 30k over what quadplexes are going for in my area and I don't fully understand what's going on here. My main question is, can a property be bought before auction if there is a notice of sale posted? If yes, wouldn't this almost be considered an extremely motivated seller, so why try to sell so high? Thanks for y'alls responses.
