help determining ARV of duplex in Colorado

[Beth Liesenfeld]

We have a duplex under contract to fix up and flip, but we are making it into a "legal" duplex (yes, we are verifying zoning) and officially making separation between the units. I'm an agent, but I'm having a hard time comping it for ARV due to the limitations of my CMA programs. What are you tips/tricks for finding comps? Any comp programs that you like for multiunits? Any techniques you have to share! Thanks so much for the help!
