Well, the short answer is that it depends on the type and purpose of the easement. A utility company, for example, might claim an easement on the edge of your property to run new sewage lines or power lines. This could result in the loss of space, or just temporary loss of space and use while the new utilities are installed and usually aren't a problem.
But there are other types of easements that could have a greater impact on you. While these situations are not common in most situations, understanding what an easement is and how it can affect you is an important consideration as you look to list or look to buy.
