To use an Appraiser or Not?

[Krystyna Schexnayder]

My husband and I are starting our BRRRR journey and have found a few properties of interest. We are having our contractor come out to view the properties with us and provide rehab estimates, but we are wondering is it also necessary to have an appraiser come out and help with the ARV or should I just run comps to come up with an estimated ARV (im a real estate broker)

When analyzing your deals, whats your process?

Thanks for any and all feedback/ suggestions.
