In 1999 I paid $255K for 157 acres ($1.6K/acre) in Mendocino Co. California. It is timber production zone (TPZ) so it has low taxes. I could probably get at least two times that now just for the land, three times that with the improvements I have made, and at least six times that if the whole plot was suitable for growing wine grapes.
I am trying to sell my 33 acres and home in Huntington West Virginia and hope to get around $200K. The land, if it didn't have a house, would be valued at between $1.5 and $2K/acre.
