Tax foreclosures in NC are handled by the County in which the property lies. Try calling the Clerk of Court, Civil Filings division for information on upcoming sales. Be sure to do all your research, as you are not allowed inside any home and you take title as-is. I have good contacts with real estate attorneys if you find something that you are interested in bidding on. I can also get you info on private mortgage foreclosures in the Triangle area (durham,raleigh,chapel hill).
