Question about Lien on Upset tax sale Purchase

[Ray Slack]

Hello all my PA genius investors! 

Need some advice.  I purchased a property at Luzerne County PA upset sale and I know I'm responsible for liens/mortgages ect. 

My question is this.. there is a PA commonwealth lien from 2008 against the prior owner for Cigarettes' tax.. (I assume he owned a convenience store or something)  for $7,000. 

The property sold (to me) at the upset sale for $17,000 The Taxes and costs due to the county were about $5,000 leaving funds to payoff the $7,000 lein on the prior owner. 

My question is will the excess funds go towards paying off the Commonweath lein? or will those funds go to the prior owner and I would still be responsible for paying off the lien. ? 

If I am still responsible for the lein any tips or advice on the ability to negotiate the 12 years interest they are probably going to want to charge on the lein? 

Thanks for any input

Ray
