What happens to the Liens on a defaulted property listed on a TAX

[Orian Rama]

Hello,

I was wondering if someone had some insights on what happens if someone wins a property Tax auction bid on a defaulted property.
I saw a property listed for tax Auction and with some more due diligence I happen to find out that the property has two mortgage liens. If I win the auction, do i have to pay also the remaining balance on the mortgages? I ask this because the county website is a little vague and it is stating that some liens maybe dischargeable and some not. what are some instances that liens can be eliminated?

Thanks!!
