Whatever info you get from the 2003 sale might not be that useful 6 years later. It does look like when it was purchased in 2003 it was also an estate sale so I would imagine improvements were made after that purchase. The sales price now of $85,000 seems to be a great listing price for the area. If you are interested in moving foward on the propery, you would have the opportunity to elect a home inspection to have all the systems looked at as well as the roof evaluated. Also, you can view the sellers property disclosure statement which might have some useful info as well.
