Estimating potential rental income

[Zachary Schimenz]

I'm analyzing a bunch of properties at the moment, what's your go-to way of estimating the amount of rental income you'll make on a property?

Right now I'm just typing in "rent house in (zip code)" which gives me a general idea, but there aren't usually a lot of properties that also have the same amount of beds/baths, square footage, etc.

Is there a better way to estimate rental income? If you have something that works for you I'd really appreciate it!

Thanks, 

Zach
