I know a few good agents in Asheville. You could look at the HUD.gov website for HUD homes. There are some other government sites. To search for all I would recommend getting a local realtor that can look in the MLS and find you what you are looking for. If you go to the site below it will direct you to a HUD web page that will give you a choice of federal departments you can search thru their homes. I did not see anything for Asheville or any of the surrounding areas ie; Skyland, Arden, etc. under HUD or VA. So you can search the other sites IRS and such but, your best bet is still to get a local realtor.
Hope this helps

Google "foreclosure listing service" for your area. Nearly every major city has one or more of these services. They are basically just taking the information available at the county recorder's office, and other sources, and providing it to you in an easily readable format. Nearly every state requires that a foreclosure be prefaced by a "lis pendens", or notice of default. These must typically be filed at the county court house in the county where the property is located. Listing services cull the county recorders for new notices and dates, and then post that information for you to access.
Now, this doesn't speak to the process of buying foreclosures, which is a different question. Since most people who say they are interested in foreclosures are really saying they want to find a property at what seems to be a signficant discount to market value, you should also investigate pre-foreclosures, short sales and distressed properties. Sadly, many foreclosure properties are now distressed, either due to poor maintenance on the part of the home owner, or outright destruction.
Either way, these can be a good source for discounted properties.
Also, check out the following 2 links, one for short sales, and one for foreclosures, on about.com:
There are companys that sell list, I would avoid those. You can use a buyer's agent in your area, which is almost always no cost to you and you can search http://www.hmbireo.com for HUD homes, but you must use an agent to submit an offer, again in most cases no charge to you. I would recomend finding an agent you are comfortable with and let them do most of the legwork for you.
