Best Way / Website for locating owners of vacant property

[Chris Wolfe]

Hey everyone-

There are several vacant properties in disrepair I'm looking to find the owner.  I've done it before, just through the easy methods of searching google for a phone number, property records etc.  But is there a good skip tracing website that has better info for finding phone numbers, emails etc?  I'm in california (fresno county specifically).  Any advice would help!
