Good landscape design can add up to 20 percent to your home’s value, so it’s no surprise that poor exterior choices can have the opposite effect. When preparing your home to sell, it’s important to consider features that might have a negative impact on potential buyers. In addition to these features, “poor planning, bad material choices, or lack of a cohesive project can all negatively impact home value,” says landscape architect Gregg Spadaro, of LAND Identity in Westfield, New Jersey. “Approaching landscaping without a plan is like building something from Ikea without an instruction manual,” he says. These considerations will help you create a landscaping plan that maximizes your selling potential.
