There are some very easy ways for you to enhance the curb appeal of your home without investing that much time and energy.

Dress up the front door
Your home's front entry is the focal point of its curb appeal. Make a statement by giving your front door a pop of color with new paint or by installing a custom wood door. If you are in love with your door as is give it a good clean and use metal polish on the door fixtures if they are a raw metal finish, or wipe down with warm soap and water.  To protect your exterior fixtures you can use a coat of a product like Turtle wax.  This will allow water and other elements to bead on top instead of permeating the finish.  Your entry should also reflect the home's interior, so add some details that reflect your personal style.  This could be a wreath or something as simple as a new door mat.

Replace old hardware
House numbers, the entry door lock set, a wall-mounted mailbox, and an overhead light fixture are all elements that can add style and interest to your home's exterior curb appeal. If they're out of date or dingy, your home may not be conveying the aesthetic you think it is. These elements add the most appeal when they function collectively, rather than as mix-and-match pieces. Oiled-bronze finishes suit traditional homes, while brushed nickel suits more contemporary ones.  If you do not currently have a door knocker or a door bell they are a nice way to dress up the first impression of your home and provide a wonderful function for you and your guests.
