Watch the public announcements section of your local newspaper daily because the city or county will post a public notice of the next tax delinquent auction. These auctions are also listed as tax lien auctions and delinquent property auctions. The listing will also provide a list of all addresses that will be auctioned.
Visit the tax assessor's office at your county courthouse or municipal government building. The tax assessor's office can tell you when the next tax lien sale is scheduled and provide a list of available properties.
Visit a foreclosure listing website and look for "government owned" listings. This designation means the property is a tax foreclosure and the listing will also usually specify the amount of delinquent taxes. This amount is where the auction bidding will start. There are many foreclosure listing websites on the Internet.
