How to get comps if you don't have a real estate agent?

[Yelitza Mora]

Hi all, I would like to know a good way to run numbers against the numbers we are getting from Wholesalers. We want to move forward with our first investment property but we still don't know how to identify if a deal makes sense or not. 

I am getting deals daily from wholesalers, in paper they look good but i don't have a real estate agent to run numbers for me.
