Agree with Terrel-typical buyers do not do H & B use tests and in land transactions when prices are low it's often just pure speculation on the wish and hope a future event happens. There are also cases where a property is purchased to create a buffer between two neighbors who dont like each-other. I had an-Uncle who once purchased an-adjoining lot because the neighbor two lots over had a dog that barked too much. Then my uncle used that vacant lot for the next 30 years to park his trucks on. His H & B use analyses was originally based on nothing but utter contempt for his neighbor and he said he way over paid for the lot but it was worth every dime. Go figure his H & B use analyses consisted of nothing but extreme buyer motivation to get farther away from his neighbor. The same goes for how Realtors come up with list prices, they do no individual line item +/- adjustments but in some cases there estimated values are really similar to what appraisers arrive at.I have heard plenty of lot buyers say they bought something just to control who and how something is developed... Or not developed. My neighbor bought a 10 acre parcel that had been landlocked for 50 years after a road was closed. The road to the parcel could have been reopened as a dead end to the property. It was on a hillside and overgrown with trees. The owner inherited it 40 years earlier and when he died, heirs decided to sell. The neighbor offered a premium to prevent someone from making it into a building site next to him. Its HBU is a moot question and when have you heard a buyer say they analyzed HBU when buying property? Buying a buffer is easier to do when and where land prices are cheap.
I keep saying this: the more accurate default on the situation of the 2-lot assemblage in general isn't "never" but it also isn't "always".
Correct you are.
That some folks can't understand this is (almost) amazing.
Carnivore, we already did the HBU analysis.
Fannie issued guidance on loan eligibility of the subject property in a not uncommon scenario: subject is adjoining parcels a(improved) and b(unimproved) sold together by same owner.
I understand what George is saying here 100%. Our disagreement is only what constitutes the best market data to support our conclusion. We have this sale of the subject example on Garfield in 2016 and again in 2018, and also this sale on Walnut, in all three cases both lots went to the same buyers and they're still not built on. That data really stands out to me, you can write it off as atypical or uninformed if you want, and use other lot sales instead. Given the scope of work, I'll hang my hat on that and say that the MV for our subject property A+B is the MV of A plus the value in use of B. If you prefer, you can turn down the assignment or provide multiple values. As an appraiser my business philosophy was to solve problems for my clients, not create them. I will agree with Lee that in the case of a refi with no data this is a sticky situation and therefore Fannie should have worded the last sentence of the newsletter better to include something like "might" or "may".
The lot on Walnut does not have the same HBU as our subject, it's zoned for multi family. Also the appeal of the main home would not be impacted much by the development since it's already on a nice large parcel off to the side vs a small flag lot. The vacant lot on Garfield is really marginal and the appeal of the main home would be greatly impacted by the development. The most profitable is not the most probable in this case.
We made a $418k mortgage on this property that you valued at $440k. However, 30% of that $440k value is attributable to the separate vacant lot, whereas the improved parcel only contributed $310k. If you had told us the value of the house by itself was only $310k we would never have put a $418k loan on that property."

Sorry, cuz, data inaccuracies occurring outside of the appraiser's SOW isn't the appraiser's fault. That's one of the standard assumptions and limitations we assert in every appraisal report we sign. There is no overlap between that and the appraiser not doing (MV) what they say they're doing.We made a $300,000 loan based on the GLA at 2,500 sq ft, when the house was only 2,000 sq ft. Only if you could have verified the correct sq. ft. we would have never made the loan at 300,000.
Blame it on the third party inspector or Fannie in the case of multiple parcels.![]()

Different zoning? WTH? Both sets of parcels are reported in the County GIS app as being zoned RD-5 and the vacant parcel on Walnut isn't a corner lot.

As for the appeal of the vacant lot on Garfield, it fronts the street. It's the SFR parcel to the rear which relies on the dominant driveway easement for access. All this does to the vacant parcel at the street is reduce its usable lot area to maybe 6000sf.
