HOW IS EVERYONE COMPING APARTMENT BUILDINGS

[Allison Meggison]

I've searched all over the forums here, I don't have access to CoStar. I need comps on a 31 unit apartment building in Phoenix, 7 two bedrooms, two studios, and the rest are one bedrooms. When I type the address in google it only shows sites like trulia and realtor, neither have comps that are actually comparable to this building. The building is 15,794 sq ft
