Best List to COLD CALL!

[Roger Covin]

Hi BP Community,

I've been wholesaling by driving for dollars and direct mail campaigns. I'm ready to begin cold calling and wanted to know what the best lists (type of owner) I should cold call? I wanted to hit Absentee Owners of vacant homes but saw a blog that said only cold call FSBOs, Expireds, NODs, and For rent. Is this sound advice? (Bonus question, can I cold call cash buyers or only send them letters?) 

Thanks BP Community!
