You've made that argument several times in the thread in lieu of contributing any original thinking of your own to it. What you're doing here is known as the appeal to authority. The assumption that they're right about how to appraise due to their status as Fannie. For that matter, Lee is doing the same when he refers to former ASB members - who at least are experts at appraising and USPAP - who agree with him.If you're saying that about me then you're also saying it about Fannie Mae, why don't you report them to the CFPB or your state board for putting out this newsletter instead of whining about in a forum?
Wrong, the vacant lot listing ended up being cancelled and the MLS shows an SFR sold for $414k with the extra parcel in the comments, once again.
This has nothing to do with HBU, everyone agrees that the HBU of the vacant lot is to build an SFR. The problem is this - nobody ever asked you to appraise the vacant lot.
You've failed to identify the subject property, failed to meet your client's scope of work ("I'm just going to give them two values and let them decide" haha the order would be canceled in three seconds), failed to demonstrate/support your value by not using like comps (A+B are adjoining and marketed at the same time) and therefore grossly overvalued the subject property leading to increased risk for your client.
You've also failed to cite any source that a property must be appraised in its highest and best use, or that HBU is equal to market value. And you've failed to answer the question: in these rather common cases, how can the market be so wrong, so often? Where are all the smart buyers? How many times can you write something off as atypical, uninformed, outliers etc, three sales in a row is not enough for you? Sounds like willful ignorance to me.
On the flip side, you're trying to tell me I violated a couple of USPAP FAQs that don't even apply to this situation. Mmmkay.
What I did say was that if I have the comparables to support a MV of $540 for the two and your report includes zero (as in, not one) actual comparable of the "house+extra" subject that you appraised it's going to be you who ends up playing defense, not me.
Nobody can claim later on that they didn't really understand what the effect on value was or what the property's attributes - including the HBU really was because I already cover that.
Ok, so my experience is that sometimes there is a reason why two parcels cannot be sold separately. Maybe it has to do with some physical property to the land (like the property percs on one parcel and the house sits on the other or some other reason). If they can be sold separately, they typically should be valued separately. You likely will determine this by contacting someone with the authority to determine this in government. Then in your report you say, per Mr. Smith in the zoning department these parcels cannot be separated. This is how we cover our liability. If the bank wants to bundle the land appraisal and the improved property they may do it themselves and can feel free to foreclose on both. However, the valuation should be separate if they can be sold separately. You risk undervaluing a parcel that can be sold separately when you appraise them together, which could be misleading.
