Which online resources are best for potential properties?

[Ryan King]

I am about to send out 280 yellow letters to vacant homes in my area which I got from a partner but if I am looking to generate a lot more potential properties, what are the best places to get leads for wholesaling? Is there one that embodies most of the opportunity sellers (i.e. probate, free and clear, tax deferred, vacant, etc.)? 

Thanks.

@Ryan KingLeadSource.com seems to have a bewildering number of dials to tweak in terms of buying leads. I haven't seen anything else that quite compares, but I'm fairly new to this as well.
