Try ushomeauction.com and realtybid.com. It is a free website and you will find homes in the area that you are interested in that are in Forclosure. Usually these homes are listed on the market or have been listed on the market. It is important that you find a Realtor in the area that you are looking to reside in so they can give you any "extra" information on the home that you might not find on these websites. They should (most of the times) be able to show you the property. (And yes there is a link through these websites that they could put the bid in for you and represent you through out the process.)
If you need help finding a Top Realtor in the Texas area let me know and I will be able to assist you through our Companies relocation program.
