Estimating rental rates with limited examples

[Ryan Heywood]

Hello everyone,

I've run into a bit of a dilemma with estimating potential rental income. The small town I'm looking for properties in currently has zero rentals on the market, leaving me with limited information. It's located close to an affluent area with a good amount of middle class jobs that is currently experiencing a housing shortage. 

I am going to ask a few local realtors, and PM companies what they believe rates might be at, does anyone have other suggestions?
