A good rule of thumb is, if you would buy a home in a certain neighborhood for you and your family, if you have one, other people will want to rent it. Not all families have the means to buy a home in a neighborhood they want, so they rent. Strive for the best property in that market's price range.
Be mindful of price however. You want to be sure you'll get your PITI paid by the rent. I can help you with likely monthly cash flow scenarios for each property you're looking at, to see if it pencils.
