P.S. - There really isn't a secret list of foreclosures. Banks can get more $ by opening them up on the MLS. Plus they would get bad publicity if they were selling them to their buddies before the public. However, many agents have traditional sale pocket listings that they release to their buyers, friends, and family early. So if you get friendly with some listing agents you might be able to score a sweet deal.
from your questions, it sounds like you need an agent that specializes in investment purchases, most of HUD homes are for first time buyers and owner occupant and you will have hard time buying a home through HUD for investment purposes.
