I realize your question was posted Dec '07, however, just in case if you are still interested in Amelia National, 2008 has seen dramatic price decreases with several short sales which ultimately affects the per square foot value. Also, the per square foot value is based on heated square footage space only. Appraisers use a plus and minus system to reach true comparative values.
I hope you have found this information useful. You can reach me easily for additional information. See below.
