I think you need to clarify why they want to appraise a portion of land. If the lender only loans on a half acre; the answer should be no. If you are appraising it for condemnation purposes, via Eminent Domain and you have a map of it; you will need to determine if there are any severance damages to the rest of the parcel. Perhaps the government wants a piece and you need to find out if the taking of the portion (cut out) affects the rest of the parcel. If this is a lot line adjustment where an adjacent owner is selling off a portion to another adjacent owner and it is legally permissible they need a map of it and you need to do a before and after appraisal before the bank will release that portion of the "cut out." Never heard this term before... If they need to put it in a community well and that is purpose of the cut out sometimes they need a before and after appraisal. If it is a subdivision, then you should be provided with a tentative subdivision map. My point is that you need to know what the scope of the work and there should be a good reason. Ask to talk to the owner and find out why they need a cut out valued; the answer for something like this is just not so simple and frankly if they are trying to get around lender guidelines because they want to sell a loan; it is not reason enough. Moreover, some lenders will not lend on properties with a lot of land because they want to avoid the risk associated with land value; getting an appraiser to break these rules is not ethical. You need to know where the "cut out" is and what it is for. It should be for a valid, ethical reason.
