Get a Realtor to work with, if they have not yet foreclosed, they can find the attorney who is in charge of foreclosing and help you out. If you don't know a REALTOR then let me know, I train agents all over the U.S and can give you some to call. Just be aware that foreclosures and/or short sales can take a long time to close, they are also usually sold 'as is' so a good home inspection and title search (to make sure there are no other liens on property ie: IRS or HOA) are vitally important.
Best wishes on finding your dream home!
