Do the lawn and bushes look neatly manicured? Could it use more? Are pretty flowers or plants framing the entrance?  Does it smell like blooms or manure as you approach the front door. Are the windows clean? Is the paint peeling?Is the grass healthy? Weeds are green, too, you know, so by healthy I mean not only green, but no weeds. Does your front door have a fresh coat of paint or stain? Curb appeal can be a chore or a family fun event. Either way, to attract the most buyers it needs to happen. And, by the way it needs to continue to closing. Curb appeal attracts people in.
