Appraising a property in Winfield IL: I have 2 questions I need help with. 1. Does anyone know what added value a property would have if it is built off of a river and how would I go about finding out.(The plat survey indicates the owner has right about a 1/4 way into the river). I have already tried pulling comps with simliar water rights but found none. I have also called several realtors in the area with no results. 2. The same mentioned house is a raised ranch but is built like a split level. (the house is built into a slight hill and the front is level with the ground, if you go down into the basement and out the back door, it is also level with the ground.) Do you count the basement level as GLA. Since it is ground level like the front. Please help, this thing is driving me crazy.
