What the San Juan County numbers mean
A median is the middle household: half of owner-occupied households in San Juan County pay more than $1,249, and half pay less. Your own bill is set by your home's assessed value, the exemptions you qualify for, and the local taxing districts your property sits in — so individual bills vary widely around the median.
Dividing the median tax by the median home value gives a derived effective rate of 0.68% for San Juan County. It is an estimate built from two survey medians, not the county's official rate, but it is a fair way to compare the local tax burden with other counties where home values are very different.

How the tax is worked out
The bill is built in stages. First the assessor puts a market value on the property. Exemptions — a homestead exemption above all — then reduce the taxable amount. Finally the combined local rate is applied. To see the scale: at the county's derived rate of 0.68%, each $100,000 of value corresponds to about $675 of tax a year, and a $400,000 home to roughly $2,700. Real bills use the official assessment and district rates, not this derived figure, so treat the example as a sense of scale only.
