If you were selling your house, your agent would go to great lengths to make sure it looked amazing from the outside. Its curb appeal is important for an obvious reason. When a potential buyer rounds the corner and sees your house, what will be their first impression? Will they be looking at a dull building with hanging gutters, brown spots in the otherwise sparse landscape, and dingy windows? A poor first impression based on the outside of your house would be hard to overcome even if the inside was a granite filled paradise.
