Doesn't matter.
The onus was on the buyer to due their due diligence before the entered into a legal binding contract to buy the house. The bank's appraiser comes after the buyer/seller/agents have all interacted in their best interests to negotiate a price. The bank's appraiser reads all those market reactions to opine a value as of the day the bank's appraiser did the inspection, for the lender's information.
The buyer had every right and opportunity to hire someone to run down permits in neighborhoods and chose not to do so. Which is an indication that the market does not care that buyers of view properties don't own the rights to the view.
New Jersey is not a rural area. As the eastern part develops all of its land that is not already preserved or under water, development moves west and north. At some point, in my opinion, there will be no unimproved (vacant) privately owned land in NJ. When that will happen, I don't know. I have not projected when the draw to NY city, and/or Philadelphia will decrease, and New Jersey is still within commuting distance of both.
There is no appraiser that will tell you they check building permits for vacant land in all neighborhoods of all subject's and all comparable sales and competitive active listings when doing lending work. There is no requirement for that either. Because the appraiser is there to read the market as of a specific date. If the market refuses to due its diligence, appraisers can only surmise that coming improvements are acceptable to the market. Because the market is knowledgeable. The market of buyers was put on notice prior to signing the legal binding contract, that the market participants were supposed to run down such things.
And to highlight this, there is no clause within a contract to purchase that says, the buyer will be reliant upon an appraiser's inspection of the property, surrounding neighborhood, or permit reviews, in deciding if the contract and negotiated price to purchase are valid, in New Jersey. Agents may place a value addenda in a contract, but again that appraiser's value is the opinion for the bank, as of the day, and is based on accumulated market reaction from knowledgeable buyers and sellers acting in THEIR best interests.
