Motivated Seller Owes Back Taxes

I am waiting to hear back from my attorney, but I would like to know the opinion of some of the seasoned investors on this site.

Long story short, this home owner inherited the house that he wants to sell. He is out of state and currently owes a couple of years worth of back taxes.  He couldn't pay it before, so I doubt he would be able to pony up the money now.

The house is in a good location and needs a moderate amount of repairs, the numbers are positive. My question is: Is this a deal worth pursuing despite the back taxes?  And what can be done about the back taxes?
