I'm appraising an REO in which the carport was converted to a guest quarter/mother in law type setup. Separate kitchen, bath, but not connected to main heating/cooling. And of course, nobody got any permits for the addition. On the comp grid I noted the quarters and made what I thought was the correct adjustment. My client wants a second adjustment made on the grid that has the net effect of giving no market value to the add on. On the REO repair section I included a "cost to cure". My problem is that the add on has market value, regardless of permit status. If I follow my clients directives, I eliminate the market value. Please, advise this struggling rookie on the best and most accurate way to proceed.
