It comes up in litigation assignments, where the attorney has found errors, inconsistencies or ideas that look like a cross-examiner's picnic.
right answer
I did a large 20 property estate earlier this year. The heirs were L bent upon selling portions of this estate because they had to raise cash to pay the estate taxes of the deceased...millions.
The IRS allows them to submit any sold properties as evidence of the "market value" of that property. But the client had to have preliminary numbers in the event the sale didn't take place in time and/or they could juggle what was sold. They would submit only the ones that I appraised lower than the sales price and the ones that were not sold.
In all, they also found that some properties were held in a separate corporation and could be taken out of the taxable pool. So my client contracted me to do the 20 properties but after the draft was presented, they took out several parcels (and each farm had more than one parcel) They took out entire farms and they just recently came back with 2 more small properties that they needed removed because they were under a different ownership on their books (the tax card didn't reflect that because the documents were not filed). They executed the sale of the properties just in time. They filed preliminary estate taxes only days later, writing a 8 figure check supposedly. They are not in the process of filing a final return and finalizing the results. At no time did they ever pressure me for different values.
If you ever suggested that the "Vero Possemus" campaign signs had something to do with possums, you may be guilty of racist Obama jokes.
