The appraiser on the property I purchased with an FHA loan marked my water and sewer as public therefore the required FHA tests and minimum distance requirements were not performed. The system has not only failed it will cost upwards of 60k to bring up to health and safety standards due to the size of the lot and having to move the well. The property does not qualify for a FHA loan due to the distance from the septic to the well as is being only 40ft. Any advice on who is liable?
min distance requirements are only required when there is both a well and septic onsite; appraiser reports what they can readily observe... you may want to check MLS offering etc -- was it originally reported correctly and was that what the appraiser relied upon? was it a typographical error - i.e. simply a case of the wrong box was checked?
Did the system fail AFTER PURCHASE after it was viewed/observed by the appraiser??? I believe this is the crux of it, right? And now you have a financial cost to remedy...
TBH -- i feel that your're looking to go after the appraiser or ANYONE else that you can now find fault with, now - after the transaction has closed, to recoup costs... and may be unjustly targeting the appraiser; appraiser's job is to estimate VALUE and report various conditions//observations etc (i.e. relative to FHA guidelines/requirements). Appraiser is not a system or construction expert.
DID YOU HAVE A HOME INSPECTION done? This is a more comprehensive inspection by more of a specialist to specifically determine if any system deficiencies etc are present and is typically required; if you did... the lender's UNDWR would have recv'd a copy a knew that both a WELL & SEPTIC were indeed present and called for revisions, clarifications, etc from the appraiser. What did your home inspector say about the systems??? Or, did you WAIVE having this done to make your bid more attractive [as some Buyers/realtors have done or suggested]?
Ultimately, it is the LENDER/UNDWR's responsibility to determine adequacy of collateral and it is likely them who you should likely pursue for negligence (if present) -- for the loan shouldn't have gone through if the collateral was inadequate and/or it was their responsibility to get remedied PRIOR to settlement (for which the Seller may have given you a credit, reduction in price or had to fully bare the cost themselves to do).
As part of the closing process -- you likely signed off on form HUD-92564-CN -> "For Your Protection: Get a Home Inspection"; additioanlly - you were likely provided a copy of the appraisal, closing docs, etc to review prior to closing; thus - now just may be a case of "let the buyer beware" --- but you should still consult an attorney as has been suggested.
Good luck to you and please keep us updated.
