Glenn pricing a home involves more than just price per sq. ft. you have to compare apples to apples. location,what amenities, number of bedrooms, baths, lot size, upgrades the home has and what buyers have ultimately paid for homes comparable to the home that is being valued. The process of an appraisal takes an expert who is valuing an individual property and comparing it to other individual properties in similar locations, sq.ft. lot size, upgrades and how these upgrades translate into value added to the property. There is little to no accuracy in a website valuation of homes in a whole town.
