One of the first things that people will notice is crumbling paint and bland or tired and faded colors on the exterior. If the outside of the home is rather unimpressive potential buyers are unlikely to discover the diamond that is the inside of your home.
Another thing you can do to add curb appeal is plant low maintenance flowers and plants around the exterior of your home.
Another thing to keep in mind when making the upgrades is to clean the footpath and driveway. It is amazing what a high power pressure washer can do to your driveway and front porch. Don't stop there however; take the time to make sure your doors and windows are clean as well. These little things often make the biggest impression. If you care properly for the exterior of your home and keep it nice and shiny chances are (in the buyer's mind) that you will have taken the same care of the inside of the home that they are quite possibly now considering.
Taking the extra time to ensure that the outside of your home is attractive to buyers can translate into higher and quicker offers than neglecting the essential real estate between the front door and the curb. Do not overlook this powerful piece of advice and you should enjoy a little more success in your efforts to sell your home or investment property.
