how to calculate ARV and Apprasial Value

[Aaron Hearne]

What is a good way to calculate ARV and appraisal value. I'm pretty good at estimating the rehab cost. What tools (i.e. Eppraisail, housecanary, etc.) are you guys using. I haven't finished real estate lic. yet so I don't have access to the MLS. I could call a realtor but I'm planning on analyzing hundreds of properties and that would be hard to get a realtor to give me comps on that many.
