How to learn values of properties in a new city

[Craig Coulson]

My name is Craig.  I just joined biggerpockets and I'm really impressed by what I have seen thus far.  I have a situation that maybe someone can provide some advice on how to approach.  We bought a house in St. George 5 years ago and moved my wife here for her health.  I continued to work in Salt Lake City and commute to see her for the next 4 years. I am now retired and I'm here full time.  I want to buy at least one rental property with the plan to hold on to it.  However, I don't know the areas of the city.  So I don't know what properties are worth in the various neighborhoods or what properties will rent for.  How can I find out this type of information?  I'm in the process of selecting a real estate agent that hopefully will help.  However, I'd like to do my own independent research to learn more about the area.  I just don't know where to start.  Any help would be appreciated.
