We always hear that certain areas are cheaper to live in than others. But are they really cheaper to live in or is it only just the house that are cheaper? An example of this is Hagerstown Maryland has 3.20 a gallon regular gas but the homes are cheaper but in laurel, Md off of I95 the gas is 2.99 a gallon. I know salaries are lower across certain parts of the US but how do they claim it is cheaper to live if gas and food etc are still high? Just curious. I have had homes in MD. PA and Va and each has advantages and disadvantages. Md is too liberal and anti gun but they don't have a car tax. Va has the silly car tax and taxes personal property and in NVA the prices are really high. Pa does not tax retirement income but their sales tax is 6 percent. So is there any truth to any of the saying about, "lower cost of living".??
