Informational notice
Figures describe the median homeowner household in Alamosa County as reported to the Census Bureau; your parcel can differ. Not tax, legal, or financial advice: check the county assessor or a qualified professional before decisions that depend on these numbers.
The rate gave way faster than almost anywhere
Between the 2020 and 2024 releases the median home value in Alamosa County rose 55.6%, from $153,700 to $239,100. The effective rate fell 25.5% over the same span, a steeper move than in 94% of U.S. counties.
The median bill still rose 15.8%, to $1,024. Where the rate drops this far and the bill rises anyway, what changed is the value the rate is applied to.
Effective rate is the published median bill divided by the published median home value, so the two multiply back to the bill exactly; the rate's movement here is derived from those two figures rather than read from the rounded published rate. Both are ACS 5-year survey estimates for the median owner-occupied household, compared across non-overlapping releases. They describe what the Census published, not a local policy, assessment, or exemption change.
How to read this county's bill
Bills rose across 2020-2024, from $884 to $1,024, a gain of 16%. This is a comparison of published ACS medians, not an explanation of a particular property's assessment or tax bill.
The fullest band here is the $800 to $1,499 range, holding 1,533 of 3,719 owner-occupied homes (41.2%). The band shows where the largest share of reported owner-occupied households falls; it is not an individual-bill estimate.
Both sides of this comparison sit low: household income here is in the bottom quarter of US counties, and so is the effective tax rate. The median bill works out at 1.8% of median household income, which is the arithmetic of a modest levy on modest earnings rather than of any deliberate relief.
The share above is the median annual bill divided by median household income, a ratio of two county-level medians rather than a household-by-household figure.

At 0.43%, Alamosa County sits in the lowest 9% of all U.S. counties by effective property-tax rate. A low rate does not by itself mean a low bill: the median here is $1,024, and what a homeowner actually pays depends as much on local home values as on the rate.

Each row is a separate ACS 5-year release, and consecutive releases share four of their five survey years. The percentage beside each bill is therefore movement in the published estimate against the previous release, not a single year's tax change. The two releases largely describe the same households. For change over time, compare releases that do not overlap.
