I'd like to see your calculations.  
70% of "this guy's" property taxes may go to the Kenai Peninsula Borough.  Some goes to the City of Seldovia where the mill rate is higher than the Boroughs and a lesser value of his property value is located.  You  go on and provide the calculation.   But only a relatively small % of that goes to the School District and an even smaller % goes to the school in Seldovia.  Check it all out and report back.
