I live and work in Waterford and I think it depends on where the house is. There is much information that is needed here. Is the house you are interested in vacant? What kind of shape is it in? When you say it is comparable what does that mean? Year of construction. I have seen houses on the same street for sale and have seen as much as a $50,000 difference. The more expensive one got snapped up and the other two are still on the market.
