For Sale by Owner sales are not included in this calculation. Depending on the actual sold homes, it could have included one lower price home that skewered the numbers downward. Some Search sites cull their information by zip code, some by city or town name...I would be more than happy to do ongoing research and market analysis of the area you are interested in. It sounds as though you may be wanting to list your home and are concerned that yours may be well above the median price that was mentioned a couple months ago. These numbers are a moving target. Every sale moves them up or down. Hope that helps.
