We have looked at properties listed as Davenport but are actually unincorporated close to Lake Roosevelt.
Grand Coulee too. Lake Roosevelt View Property is a possibility too. Beautiful country looking right at Lake Roosevelt. Property with a large shop is a little harder to find there though.
Would like this to be our last move but could see us doing one more move downsizing to a waterfront house or Condo for our later years... maybe like 15-20 years from now.
