An appraiser does not complete an "inspection" -- appraiser views the site/home and then reports what they view/observe as a basis for their valuation estimate.
A HOME INSPECTION is done by a specialist and is more comprehensive - and includes actual testing of systems, evaluating the buidling structure, materials, general maintenance items, etc. If you did have a home inspection done... separate and diff than an appraisal -- what did it say about the well/septic systems? A home inspection report would clearly indicate whether or not they are onsite and provide the inspector's conclusions about their condition, along with recommendations.
Your evasiveness to my question pertaining to having an independent HOME INSPECTION done, by a home inspector (and not an appraiser), suggests this was NOT DONE? Did you waive this right... to have a home inspection done, as some chose to do (i.e. roll the dice), to make your bid more appealing... when bidding wars etc were purvasive and competition among buyers was fierce?? Should have had this done...
Or -- did both the home inspection report AND the appraisal say the same thing based on what could be readily viewed?
