Question about tax sales......

[Christopher Frey]

Hello,

We have some tax sales coming up soon in the next couple of months in Central PA.  I did some calling around to different counties to see if I could obtain the list prior to it being posted publically, and some counties said I could purchase it beforehand, and other counties said I could not.  Is there a way to access this from public records without knowing the address of the properties?  I figured I could get it from the PA Right to Know Law, but I have been turned down in some counties.  Any suggestions?  My next question is since all tax sales are final and you assume all judgements and liens,  is there some way to check if a property has a clean title without paying for a full on title search.  Is there anything else I can do to check on encumbrances on a property without paying for a title search?

Thanks for any and all help, I appreciate it!
