How to price a rental house?

[Chris Clemptor]

I'm wondering if it would be a good idea to hire a real estate agent just to give me the going rate for my rental house.  I have looked on Craigslist and Zillow, but there just doesn't seem like many options in my area.  Also, the rents seem to be all over the place.  Is there a way to compare houses to apartments and then just add a certain percentage for a house?
