Death and taxes ......
Surprised nobody has proffered the differences of market value, to appraised value, to assessed value, over time. Historical data is relevant to relevant history, however.
A point not made yet, relative to Moultonborough's available data, is on the town website in the tax/gis section, and then the Vision Property card section. The property card has "appraised value" and "assessed value" side by side. You pay taxes on the assessed value.
Market value ... in the eyes of the beholder.
Perusing the April 1st, 2017 to March 30th, 2019 Moultonboro sales report can give an idea of some recent relevance of market value to assessment.
