How do I find home government sales/auctions in my area?

I saw this informercial about buying houses in government tax sales/auctions, but how do you find them. Apparently the previous owner foreclosed and did not pay property tax, so the gov't then sells the house in an auction. But where are these so-called auctions?

I use publicnoticeads.com It is a free service from participating newspapers. If it does not cover your area, search your local newspapers online for tax sales. They are required to be published. You can also talk to your county Sheriff and they can tell you when and where the tax sales take place as well as the foreclosure auctions.

A word of caution, despite what the infomercials say, tax sales are not a good place for the beginning investor. The tax sale process is a difficult one and the properties are redeemed most of the time. That means you go through the entire process and in return you usually get your initial investment plus a small amount of interest - often 8%. Not a bad return but if you were planning to flip the property you were probably expecting more. Another important caveat, you MUST submit your expenses in a timely manner. If you do not, the property owner can redeem and not pay your expenses leaving you with a loss.
