On a typical Colorado rental, a single-family home near $450,000 renting for about $2,450, the numbers produce a 4.2% cap rate after Colorado's 0.49% property tax, insurance, vacancy, and upkeep. That is $19,016 a year of net operating income before any mortgage. The tool below is preloaded with that rental; every return measure updates as you change it.

Colorado costs behind the cap rate
Property taxes come straight off the cap rate
When taxes are assessed near the purchase price, the effective tax rate subtracts almost one for one from the cap rate: Colorado's 0.49% costs the example rental about 0.49% of yield. Assessment rates are set statewide and have declined over time; individual counties add temporary mill levies for schools, fire, and parks.
Insurance in Colorado
Budget about $2,000 a year for a landlord policy. Wildfire is the fast-growing cost in the Mountain West. Homes in the wildland-urban interface increasingly face non-renewals or sharply raised premiums even at moderate rebuild values.
Landlord rules in Colorado
No statewide rent control. Deposits must be returned within one month, and cities such as Boulder, Denver, and Aurora enforce additional tenant protections. Rules on deposits, notice, and rent increases shape vacancy and turnover cost, two of the softest numbers in any NOI.
How to analyze a Colorado rental
- Enter the asking price and the cash you'll need at closing and for repairs before the first tenant.
- Set rent from comparable Colorado leases for the same bed and bath count within a mile, signed in the last few months.
- Replace the statewide 0.49% tax rate with the parcel's actual bill; watch for reassessment after a sale.
- Keep maintenance and management in the budget even if you self-manage; your time and the next roof are real costs.
- Read cap rate for the property, cash-on-cash for your deal, and use the price table to set an offer at your target cap rate.
Methodology
Net operating income is rent and other income, less vacancy and every operating cost, before the mortgage. Cap rate divides annual NOI by the price. Cash-on-cash divides cash flow after the mortgage by cash invested; total return adds year-one principal paydown and appreciation to cash flow over the same cash.
Colorado prices, rents, and tax rates start from sourced statewide data (listed under Sources), scaled to a typical single-family rental; insurance is an estimate. Cap rates vary widely between neighborhoods; compare against recent sales of similar rentals nearby.

Colorado FAQ
- What is a good cap rate in Colorado?
- There is no single figure, but the typical Colorado single-family rental in this example earns 4.2%. Prime neighborhoods trade lower, higher-risk ones higher. The useful test is the spread over your mortgage rate: at 6.875%, this rental's cap rate is below it, so financing dilutes the cash return.
- How do Colorado property taxes affect cap rate?
- Almost one for one. Taxes are an operating expense, and when they are assessed near the price, the effective rate comes straight off the cap rate. Colorado's 0.49% costs about 0.49% of yield; that is light by national standards.
- Does the 1% rule work in Colorado?
- The example rental rents for 0.54% of its price each month, short of the 1% screen. Few US markets meet it at today's prices, so use it to sort listings and the full NOI to decide.
- How much does a rental property make in Colorado?
- On the example numbers, about $19,016 a year before the mortgage and -$7,590 after it with 25% down, a -5.8% cash-on-cash return. Adding principal paydown and 3% appreciation brings the year-one total return to 7.2%.
