Aquiring property at tax sales- Safe?

[Summer Segeleon]

I do not mean to ask about buying a tax lien, which is different.

My county in PA has first an "upset sale" , in which you are buying the actual property, but any mortgages, liens, etc. are still attatched . If not sold, property goes to "judicial sale" , where it is free and clear of liens, mortgages, etc, however, I believe you receive a "tax deed" , not a warranty deed. Will I run into issues when I try to sell this property and someone wants to finance it using traditional lending?
