Hello Fellow Big Pocket Members ,

So i'm starting to do the mailing list approach  for marking for wholesale. I just need couple questions answered before i fully start. First of all is where would i normally get a list from such as vacant or anything along that road even out of state owner ? Second how accurate are these mailing list given by sourcelist.com and other ? Last but not least are the list downloadable for personal use for Microsoft for example ? ( I might have more along the process of answering the first three )
