Finding comps

[Heather Harrison]

recently, a fellow investor and I were discussing the most difficult aspect of wholesaling. He said that he found it to be finding TRUE comps. Have any of you found that to be the case? Because I am just starting out, I'm not sure how tell the difference between "true" comps and unreliable ones. I do not have direct access to the mls yet and have been relying primarily on sites such Zillow, trulia, BeenVerified, etc. any advice on telling the difference between a good comp and bad comp without using the mls? Thanks, and happy investing!
