Foreclosure Surplus funds?

[Mikey Cas]

Hi everyone, I recently heard about a method some investors are using. It involves attending foreclosure auctions and identifying any properties that sell for a surplus over the mortgage, lien and junior liens. This amount is due back to the original homeowner, but many times they never know this money is theres and never receive it. The idea is to find these people and charge them a percentage of the surplus or an agreed amount. This sounds pretty interesting to me and was wondering if anyone has any experience in this.

Also, I went to the local county court house, to find out when the next auction was. I asked somebody and they told me to look at a sign and there were a couple of notices, but Is there a better way to find how much is owed on the mortgage and dates of auctions in a more organized fashion? Thanks for any help!!
