I have heard on infomercials and various shows that there is a way to own a forclosed home just by paying the back taxes on it. I was wondering if anyone can tell me how to learn how to buy these homes. What legal ways do I take this up? Who do I have to talk to? Who do I pay rather then buying it for it's sale price? Please help I'm trying to find a cheap place to move in soon.

You can buy properties for the back taxes IF nobody else bids them up, which they usually do.

It's better to find the owners of properties that are about to be lost to tax sale, and contact them directly to sell.
