Determining monthly rent rates for duplex in Coolidge, Arizona

[Keegan Darby]

We are under contract on a MFH in Coolidge, Arizona. Each unit is 2/1 and has window a/c units (no central HVAC). They look nice inside.

It's been difficult to find data on comparable monthly rent rates. Two questions: 

1) Has anyone every posted a listing on Craigslist prior to owning the property to determine generated interest at a certain price? 

2) For anyone local to the Coolidge area, or with property there, what are you getting on rents for 2/1?
