Buying a home from a seller that has a county tax lien

[Kevin Polite]

I've been contacted by a seller that has a tax lien on their property.  They have 11 more months to pay it off the tax plus the 20% the County tacks on. My question is should I just get it under contract and the tax lien would be paid for by me through the closing attorney? The price I'm talking to the seller with and the underlying value of the home makes this well worth it if I can get it.
