Recommendations for FMV/ARV programs?

[Sarah Ella Simrill Ray]

As a new investor, I could really use a few recommendations for programs that calculate FMV/ARV values of properties I'm looking at. I've heard Zillow is "all over the place" and I used Homelight once, but the second time I searched a property there, they called me and told me they couldn't give me the information, I think he said because they only work with investors? I AM an investor, so maybe he didn't understand me. I also looked at Ownerly and a couple of others. Any recommendations?
