Hi Fed Up,
I think you would be surprised by what is selling in Charles Town right now. Contrary to what you have been told, a finished basement, nice landscaping, and upgraded interiors ARE making a difference in sales of homes. With inventory in Jefferson County and all over the DC area lower than it has been in 10 years, people are jumping on great houses that are priced right. And a buyer for a Dan Ryan is a different breed than a historic home, etc (like BMW and KIA buyers).
Appraisals are catching up, too. Things have changed significantly in 4 the last 4 months as far as sales and comps go. I blogged about it 2 weeks ago: http://www.blackwellpropertymanagement.com/posts/1399-now-is-a-great-time-to-sell.
Locally, this has become a mini sellers market, in many expert's opinions. I agree.
Hope that helps a little bit.
