Looking for a Zero Energy Home for Sale? It is important to engage a real estate agent who understands the market value and the features of genuine sustainable zero energy homes and zero energy ready homes. A real estate agent trained in sustainable homes can help you identify whether or not the home you are considering is truly a zero or zero energy ready home, and they can help you evaluate whether a building lot you are considering buying has the appropriate southern exposure for constructing a zero energy home. They can also help identify banks and appraisers who understand the value of a truly sustainable home.
