If you're only interested in tax lien foreclosures, you can to go the Travis County website The new listings for yesterday haven't been posted yet, but you can go back through and look at the properties that didn't sell at past auctions (Resales), as well as, look at the results of the homes that did sell.
If you're not experienced in purchasing tax lien properties, I would highly suggest you hire a REALTOR® who is experienced in these types of bids or a real estate attorney. Good luck. I've had clients walk away with great deals at tax lien auctions.
