Tax Sale - Property under forclosure

[Florian N.]

I was wondering if someone could clear the following question.
What happens with the mortgage/lien if a property is sold at a tax sale(judicial PA) but said property is under the foreclosure process but not finalized yet, eg. bank started the foreclosure process but it's still on the roll.

I can't seem to find a straight answer for this one.

I understand that if the bank/lender doesn't pay the taxes the property is foreclosed on and the title will be free and clear but as the foreclosure process is already started what happens?

Thanks for any insight.
