HELP!Tenant caused $25k LIEN on MY Property for HIS Unpaid Taxes!

[Jim C.]

Just found out from my local recorder's office that my tenant's failure to pay his federal Income taxes has caused the IRS to place a $25k lien on MY property! There is also another Lien for $5k from a local hospital. Am I responsible for these? How can I get this removed? Do I need an attorney involved? Should I evict them because of this? What happens if I want to sell in the near future? Will these liens hold up the sale of my property?
