Sheriff's Sale - Federal Tax Lien ?'s

[Doog E.]

Hi everyone! Long time reader, first time poster. I found a property I'm interested in and I have some questions. The property is available via Sheriff Sale in Texas. While doing research, I found several "Notice of Federal Tax Lien" records. The unpaid balances on these far outweigh the value of the real estate. I should note the real estate is a small tract of land with no structures. 1) Do the Federal Tax Liens transfer to me if I buy the property at the Sheriff Sale? (I would receive a Sheriff's Deed w/ no warranty) 2) If so, how do I clear the Federal Tax Liens? I'm under the assumption that the Federal Tax Liens do transfer, but the IRS can't expect to receive such a large amount for that particular tract; therefor, what steps are necessary to resolve the liens? Thanks in advance.
