Skip Tracing for Wholesalers

I recently started skip tracing and searched the internet and Facebook groups trying to find the most reliable data out there. I came across Batch Skip Tracing among many other providers. It seems everyone has an opinion about who has the most accurate data. Any time I am researching a new service for my business I use a couple of criteria to determine whether a service is legitimate or being hyped by Gurus to make a quick buck from unsuspecting people.
