I'm throwing this out there................ Here's the situation: An owner has lived in her house for 10 years with no previous flooding. Recently, her property was declared by FEMA to be in a flood plain. To what extend would that affect the value? (if any). The owner now feels her property is now worth less because of this new designation. ( Note:There are no other sales in the area that are also in the same flood plain) And, for future reference....Are they any resources for appraisers out there either by FEMA otherwise with guidlines on how to determines property values located in a flood plain? Thanks to all !!!
