Take a good, hard look at the outside of your home, since that's what potential home buyers see first. If you've ever bought a home, you know that you passed by houses simply because they looked shabby and unloved from the curb viewpoint. It's just a quirk of human nature that makes a person think that if a home looks bad from the street, it will be just as bad on the inside--so don't let your home make a negative impression from the first glance.
