My wife and I recently purchased a new home in Tennessee. Here are some helpful hints we picked up along the way:1. Use all of the online resources available. Almost every state and local government has a website where you can research real estate information. The data on home sales, taxes, and neighborhoods is invaluable when you are shopping for a home. We were able to find out the most recent sale prices in the neighborhood we selected, and we didn't have to rely on a real estate agent to get.
