40.5% of homes in Montrose County are overassessed.

Montrose County is a Colorado county with an average effective property tax rate of 0.45%. Colorado assesses residential property at 6.95% of actual value (the 'residential assessment rate'). Your tax bill equals actual value × 6.95% × mill levy. Over-stated actual values directly inflate your bill. But here's the problem: the Montrose County Board of Assessors is responsible for valuing tens of thousands of properties every year using mass appraisal models that cannot account for the specific condition, improvements, or market dynamics of your individual home.

According to statewide Colorado property tax data, roughly 40.5% of residential properties are assessed above their true fair market value — meaning homeowners are legally being charged more than they owe under Colorado law. In Montrose County alone, that's an estimated 8,100 households paying too much right now.

At the county's 0.45% effective rate, every $10,000 of overassessment costs you $45 per year. Over a nine-year median homeownership period, that's $405 lost on just $10,000 of excess assessed value.

The Montrose County assessor is responsible for valuing every property in the county annually. Mass appraisal models make systematic errors — and Colorado law gives you the right to correct those errors through the formal Board of Assessment Appeals appeal process. The county has no incentive to notify you when you're overpaying. You have to check yourself.

Colorado appeals begin with an informal protest to the county assessor (May 1–June 1 deadline). If unresolved, you can escalate to the County Board of Equalization (CBOE), then to the State Board of Assessment Appeals (BAA). To win, you need evidence. The most compelling evidence is recent comparable sales — homes similar to yours in Montrose County that sold at prices implying a lower value than your assessment. A licensed appraisal is also highly effective.

Your assessment can only go down from an appeal, never up. Colorado law prohibits assessors from raising your value as a result of an appeal you initiate. The only risk is the time it takes to file — which is why Fairmark does it for you.

These figures represent the average overassessment in counties with Montrose County's tax profile. Your specific situation may differ — the only way to know is to check your assessed value against what your home would actually sell for today.

86% of pre-screened appeals in Colorado result in a reduction. The assessor's office knows their valuations are imperfect. When presented with credible evidence, they typically settle.

Nationwide, only about 5% of eligible homeowners appeal their property tax assessment each year — despite roughly 40% being overassessed. The gap exists for three reasons:

First, 53% of homeowners don't know they can appeal. The annual tax notice contains a legal disclosure of your appeal rights — but it's buried in fine print that most people skip. The county is legally required to disclose your appeal rights, but not to make them easy to act on.

Second, gathering evidence feels overwhelming. Pulling comparable sales data, analyzing assessment methodology, and building a credible case against the county's own records takes time and expertise most homeowners don't have.

Third, the county has no incentive to help you. Every dollar of overassessment is revenue. The system is designed to be just difficult enough that most people give up. We don't. Enter your address above and we'll show you exactly what you're overpaying — for free.
