Texas Warranty Deed Vendors Lien and online Auction.

[Lisa Smelter]

I have registered for my first online auction and found a property that has a vendors lien.  If a lender has a warranty deed vendors lien listed on the tax assessors site and it is being auctioned as a bank owned property, would the winning bidder be responsible for the outstanding vendor lien?  How can I find out how much the vendors lien is?  I would also be grateful for any information that I could learn more about online auctions.

Thanks for your help.
