Trustee Sale - IRS lien on previous owner

[Neha Wadhwani]

I am considering a property being auctioned at a Trustee sale in Texas. Current owner is a bank. However, I noticed that the previous owner has a $20k IRS lien on him. The IRS lien clearly states its a claim on all his property, but is not specifically attached to the subject property being auctioned. 

If I buy it, will I get title insurance? If Not, then do I have to go through a quitclaim process or negotiate/pay off the IRS lien to get the release? Which would be cheaper from an attorney costs perspective? Thanks in advance
