Denver County, CO — Property Tax Underwriting Guide
Colorado · Cyclical hold until revaluation
What this means for multifamily underwriting
Denver multifamily benefits from a biennial reassessment cycle with a 3% cap between reappraisals. Post-2023 legislative changes to residential assessment ratios have added complexity; confirm the current classification.
Transaction type breakdown
Colorado conducts a full reappraisal every two years (odd-numbered years). Between reappraisals, Actual Value growth is capped at 3% per year. A sale does not trigger an off-cycle reassessment.
Refinance has no effect on the assessed value.
Ownership transfer does not trigger an off-cycle reassessment; the biennial cycle governs.
Tax appeal information
The 6.0 mill placeholder (0.6% of market value) is a simplified estimate for Denver multifamily. Colorado's assessment ratio for residential multifamily changed materially in 2023-2024.
