HUD Foreclosures - Need Help !!

Can anyone out there shed any light on HUD Foreclosures? I understand that as an investor, I will be getting secondary consideration to anyone wanting to buy one of these houses for themselves to live in. (O/O) If O/O offers are not accepted and HUD looks at investors to sell the house to, do you have any idea what kind of percentage of the “list price” HUD would accept. The listing realtor said they may consider 80% of list. Does this sound accurate ??

Any other pointers on HUD Foreclosures would be of great help.

Thanks in advance.
