How To Determine If A Location is Good for a Rental

[Kyle Scholnick]

Anyone have any tips on how to determine if a certain area is good to have a rental property? I am just outside of DC so in order to find affordable rental options I need to go more into the deep suburbs/rural area in places like b/w Culpepper, VA and Richmond, VA. But since these areas are less populated and not near a major city, how do I determine if it will produce consistent renters or if vacancy will be high?
