Many buyers form an opinion of whether or not they are interested in a home before ever stepping through the front door. Therefore, your home's curb appeal is your first and best chance to make an excellent first impression on the buyer. You may have spent a lot of time and money updating the interior, but if the exterior of your home screams "help!" you've already lost the sale.
Exterior renovations may not be as exciting as getting the interior into tip-top shape, but it's possibly even more critical. Landscaping, the physical exterior, and the facade of your home are all important factors that you should consider and are vital to selling your home for top dollar.
