Side Note:

The Home Values Website's Value Accuracy, according to their companies own data (Click Here), is that 60% to 80% of values are within 10% of the selling price and 20% to 40% are off by more than 10%.

The site gives a good overall view of properties and comparables with adjustments needed for lot and structure square footage as well as condition and location. Specialty properties such as View, Waterfront, Acreage, Custom Built Homes, etc. can be off considerably.

An Experienced Realtor can further refine a properties true and current market value based on market trends in an area coupled with a visual inspection of the property.
