Tools for determining average rent in an area, and other apps?

[Faiz Kanash]

Hey guys!

I was just wondering if anyone had any tools or apps they used when they determine a multifamily property to purchase? I know about rentometer, but I don't want to pay for a subscription really when I know i'm not going to be using it often. I occasionally come across multifamily deals where I work, so I want to check average rent prices in the area to see if its a good enough deal for me to snag myself, but it isn't a constant occurrence where it justifies me paying a subscription you know? I've been using Zillow, but i'm not quite sure if its really that accurate, so I wanted to see if any of you guys had any suggestions, or do you primarily stick with rentometer to determining average rents?

Also, any other useful apps or websites you use to help you in your rental property purchase? I'd love to hear any recommendations, thanks!
