Indeed, and the mechanism for adjusting any unfairness in assessment you encounter there is always going to be more byzantine than a fair self-assessment, and probably impossible in practice.

E.g. let's say you live in a neighborhood where everyone's paying a premium for fanatic views. Except your house is the only one that doesn't have that view.

Even in such an obviously unfair scenario the government is likely to stick to some assessment that's going to be unfair, e.g. some mean sale value of the N lots adjacent to yours.
