I just did an FHA appraisal on a rural property on 9 acres with a private well pump and septic. Comment was made in the report "No readily observable septic or well pump defects were noted at the time of inspection. The appraiser has no obligations to measure the distance between the well and septic or lot lines however it was noted at the time of inspection that septic and well distances meet FHA minimum setback requirements. The septic tank is at least 50 feet from the well, the septic drain feed is at least 100 feet from the well and the well is located at least 10 feet from property line." The lo wants me to go back out to the property and physically measure the distances. Can the appraiser do this or does a qualified third party have to? I am definitely not an expert in the septic/well pump field. No survey was provided to me therefore the location of the septic and drain field was supplied to me by the ho. I could physically observe that the well pump was at least 10 feet of property line but how would I know its exact location from the property line? And without being able to see the septic tank and drain field, how will I be able to get a true measurement of the distances from the well to septic and well to drain field? Any advise would be greatly appreciated.
