The property I am appraising is completely off the grid. Electric is completely provided by solar, and additionally this borrower has a windmill to help keep the batteries charged. From the market standpoint, I'm thinking that this represents a functional utility problem and there are no comparables that I can find that replicate it. How do I adjust properly for the functional problem? I'm thinking that 10% is an appropriate penalty - is the 10% applied against the sales prices of the comparable sales?
