@aaron_renn That is a strong percentage. Lots of other markets just don't have the type of office buildings that can be converted due to physical conditions of the property (ie floor plates are too large) or the economics don't work.
@shagbark_hick I tried searching for these types of homes in Wisconsin. I was shocked to find there really very little under $50k. Upstate NY lit up like a Christmas Tree. I just assumed a cold midwestern state would have more of this type of housing available.
