What's the next step and what are my options to purchase house?

[Galvin Duesler]

Hello Everyone! 

I recently went to a tax sale to familiarize myself. Prior to the sale I walked some streets and searched the deeds of the properties I liked. A few of the houses I am interested in were not bid on at the sale and the owners are deceased. The tried locating the heir of the estates but have come up with nothing. Can anyone point me in the right direction? Any help would be greatly appreciated

Thank You,
