AUCTION.COM - Do we get a Clear Title with Online or Live Auction

[Rath Yelandur]

I am new to REI. I am in the Houston area. Lets say - one purchases a property by bidding online or at LIVE auction with AUCTION.COM.

Do they get a CLEAR TITLE or they still have deal with hidden Liens ?

In the documents they list along with a property,  they do provide some information regarding outstanding mortgage.  

How do I find out what Level LIEN I am bidding for ? i.e Is it Tax, Mortgage, HOA, or some other lower level lien?

Thanks.
