Go through your photographs and find the best from each season. Give these to your agent to copy and use as part of the material given to every open house guest and potential buyer who tours your home.
If you have a rose garden or tulip bed that’s dormant right now, show a photo of it in all of its glory. If you have flowering shrubs or trees, show them in bloom. If you add lights to a tree in the yard for the holidays, include a photo. If your back yard is stunning in moonlight, show them!
