How To Negotiate Tax Liens

[Oraude Boston]

Hey Bp Fam, I have a Abandoned property of interest which needs A full Rehab located in Orange New Jersey. Seller just wants to get rid of the property. This property has tax liens of about 14k as well as a Blight Notice. My Question is how do I go about negotiating this lien down with the county. Are they any pointers or advice I need to know when negotiating tax liens. Are they any specific way or negotiating tactic when dealing with this issue. P.s This would be my first Deal so just looking for any input on this matter
