Philadelphia back taxes

[Derrick Alexis]

Hey BP community,

I am dealing with a new potential deal where the ARV is definitely there along with the rehab costs. The seller is insistent that he does not want to pay the owed back taxes of $37,500. He also states that there's a way to have the purchase go through even with a lender and have the taxes paid on the back end.

Are there any Philly investors who have dealt with this before? If so, how would it be done?
