Best way to find accurate comps

[Matt Doubell]

Hi currently I'm working on starting my real estate journey and and I am extremely interested in doing BRRRR deals. I have a large background in rehabbing both as a contractor and now an engineering working with contractors often. Due to my technical background I very much enjoy fixing up houses. From a rehab standpoint I would say I'm very comfortable giving accurate estimates for the overall cost to rehab. But an area where I'm not near as comfortable is estimating the ARV. My initial thought process is that comps are the best way of estimating an ARV. Is there flaws in this way thinking? Also what are the best ways to ensure accurate comps and accurate ARV estimates? I would appreciate anything y'all could share to help me keep moving in the right direction. Thanks for your time
