How convenient your neighborhood is can affect your happiness -- and your wallet. Is there a shopping center nearby where you can accomplish several errands at once -- pick up your groceries, fill a prescription, find a last-minute hostess gift? Easy access to stores you frequent on a regular basis is key to keeping your stress level to a minimum, as well as avoiding spending too much money on gas. But the biggest convenience factor regarding your neighborhood's location is probably your commute to work. Unless you telecommute every day, the distance you have to drive to and from work is something you need to consider -- especially if you live in a city that is notorious for rush-hour traffic. You might find the perfect house in the perfect neighborhood, but if moving there will double your commute, will it really be worth it?
