Hi VZWKELLY,
I'm not sure why you would not want to ask this of a Realtor as they most likely will have the right answer for you. I ran some numbers for Greene County and here is the result:
time period: 1/1/2004-12/31/2004 (most would consider a healthy market)
107 properties sold with a well
140 properties sold with public water/public water access
time period: 1/1/2007-12/31/2007 (most would consider a changing/declining market)
81 properties sold that had well water
100 properties sold that were on public water/public water access.
So - it doesn't seem to make much difference. There are micro-markets within each market. In my experience if someone bought high, they are often not willing to sell low. However, if you can find a re-sale property that was not purchased at the peak and Seller is willing to be reasonable you can get a great price... and in 3-5 years from now, hopefully still be under the competition price wise....after all it's the price, condition, and location that are the 3 biggest criteria which determine how quickly a property will sell. Hope this helps. Disclaimer: I am a Realtor in Charlottesville, VA

In addition to Greene: I hear Forest Lakes, Chesterfield, Deerwood, Hollymead, etc. are popular in the 29 North Corridor. My wife loves North Pines off of 29 North.
