DENVER REAL ESTATE | COLORADO LIFESTYLESThe short answer
Property taxes are a recurring ownership cost that can differ substantially between Denver-area addresses with similar prices. Use the actual parcel record, taxing authorities and a realistic estimate of the completed property’s assessment. Divide the annual amount by twelve for budgeting, but remember that an escrow estimate is not a guarantee of next year’s bill.
Read the parcel record before comparing homes
Confirm the county and parcel rather than rely on a mailing address or listing summary. Review the latest actual bill and identify every taxing authority. Ask whether the displayed amount reflects the entire property, a prior owner’s exemption or a partially completed new home. A low historical number can be accurate for its period and still be a poor estimate for your ownership.
Separate market value from taxable calculations
The purchase price, assessor’s actual value and assessed value serve different purposes. Denver’s assessment guidance explains that valuation and taxing-authority mill rates both enter the tax calculation. Do not apply a remembered statewide percentage to today’s price and call it precise. Use the county’s current guidance and ask about any changes that are not yet reflected in the last bill.
Convert annual differences into a useful comparison
If two otherwise comparable homes have hypothetical annual taxes of $4,800 and $7,200, the difference is $200 a month. That is arithmetic, not a claim about typical taxes in any neighborhood. Add the difference to insurance, dues and mortgage costs before deciding the less expensive house is the less expensive ownership choice.
Leave room for future changes
Your budget should tolerate a bill that changes after reassessment or tax-authority decisions. If taxes are escrowed, ask the lender how a shortage or updated estimate affects payments. For a new build, request a completed-home estimate from the appropriate professionals and retain its assumptions. I would avoid making a home affordable only by using the smallest historical tax figure available.
Your decision checklist

Common questions
Does buying at a higher price immediately set my tax bill?
Do not assume the purchase price directly becomes the bill. Colorado valuation and assessment procedures apply; confirm timing and treatment with the county.
Are property taxes included in the advertised mortgage payment?
Sometimes, but not always. Ask for a breakdown and verify whether the estimate uses the exact property.
