Buying a home should be an exciting, fun time for any family. Unfortunately, many end up with bad experiences because they didn't do their homework first. Before you buy a home, there are many details you can't afford to overlook. Once you're approved for financing, the house has passed inspection and you are ready to move in, there may still be one problem with your home you are unaware of. In order to cross everything off your list when buying a home, you may want to first check to make sure you don't have a mechanic's lien against it or determine if you are responsible for it.
