Here's a link to a website that contains info on all Texas counties:

If you find something that interests you, I'd be happy to help you with your purchase.
As a side note, you might want to look for either a title company or attorney to research the title on the properties you are considering to bid on.
You might want to consider working with a licensed realtor.
I would be happy to provide you with a list of active homes on the market - both foreclosures and non foreclosures.
Hope this helps
