So let's look for something that's sold. One block down from your example, we have a home that just sold a few days ago. Also for $27.5 million, coincidentally - but this one is improved with a 12,000 square foot mansion on it and is on four acres:

$29M on 4 acres. You understand that if I take this as the baseline, it still makes the judge look bad?
(MaL on 17 would be $123M).

Perhaps because Mar-A-Lago is encumbered with a historic preservation easement, which prohibits not only changing the exterior (which is burdensome but common for single-family residential historic properties), but also portions of the interior? Or the deed restriction which prohibits it being used for anything but a private club, which is an extraordinary burden on the Property?

Yeah, because nobody would buy it as a resort.

So the Property Appraiser got the appraised value approximately right for your example - but is off by 1800% for Mar-A-Lago?

Ahem.
Market value /= appraised value. When a property sells, then the two are one and the same but not before.
