Should You Rent or Sell Your Denver Home? Taxes, Timing and the Real Math

The question most Denver owners face

You're relocating, upsizing or moving in with a partner, and you own a Denver home with a low mortgage rate. Sell it, or rent it out?

There's no universal answer, but there is a clear way to decide. This guide walks through the money, the taxes and the Colorado-specific rules. It's general information, not tax or legal advice. Run your numbers with a CPA before deciding.

Step 1: Will it cash-flow?

Start with real numbers, not hopes.

Rent: use leased comps from the last 60–90 days. For context, Zillow's Observed Rent Index for single-family homes in the Denver metro was about $2,930 a month in September 2026, up about 1.6% from a year earlier. Your home could rent well above or below that. Our pricing guide explains how to set rent.

Monthly costs:

If rent minus all of these is negative, you're paying to own a rental. That can still work if you expect strong appreciation, but go in with eyes open.

Step 2: Understand the tax rules

The home-sale exclusion

When you sell a main home, you can generally exclude up to $250,000 of gain from income, or $500,000 if you're married filing jointly. To qualify, you must have owned the home and lived in it as your main home for at least 24 months during the 5 years before the sale. The months don't need to be consecutive, and you generally can't have used the exclusion on another home in the previous two years.

The practical consequence: if you've lived in your Denver home for at least two years, you have roughly three years after moving out to sell and still meet the 2-of-5 test. IRS rules also say that time after you last lived in the home, within that 5-year window, doesn't count as "nonqualified use," so renting during that window doesn't shrink the exclusion. Confirm your dates with your tax advisor.

Depreciation recapture

When you rent the home, you depreciate the building (not the land) over 27.5 years. Depreciation lowers your taxable rental income each year. Your starting basis for depreciation is the lower of your adjusted basis or the home's fair market value when you convert it to a rental.

The catch: the home-sale exclusion doesn't cover depreciation. When you sell, gain equal to the depreciation allowed or allowable after May 6, 1997 is taxable, generally at a maximum 25% rate. "Allowable" means you owe it even if you didn't claim the deduction, so claim it.

Rental losses

If your rental shows a tax loss, you may be able to deduct up to $25,000 of it against other income if you actively participate in managing it. That allowance phases out between $100,000 and $150,000 of modified adjusted gross income, with different limits if you're married filing separately.

Property tax

Colorado taxes residential property in one residential class, and a long-term rental home is generally assessed in that same class as an owner-occupied home. For 2026, the residential assessment rate is 7.05% for school district levies and 6.8% for other local levies, after a value reduction of 10% of actual value up to $70,000. Your actual bill depends on your local mill levies.

Step 3: Check your mortgage and insurance

• Mortgage: many standard home loans require you to occupy the home as your principal residence within 60 days of closing and for at least one year. After that, converting to a rental is common, but read your loan documents and talk to your servicer if you're unsure.
• Insurance: a standard homeowners policy may not cover losses while the home is leased. For a typical 6- to 12-month lease you'll likely need a landlord (dwelling) policy, which costs about 25% more than a homeowners policy, according to the Insurance Information Institute. Call your agent before the tenant moves in. See our landlord insurance guide.

Step 4: Know the Colorado rules before you become a landlord

Being a landlord in Colorado is more regulated than it was five years ago:

• Denver rental license: required for any home rented for 30 days or more. See the license guide.
• For-cause tenancy: since April 2024, Colorado landlords generally need a legal reason to end or refuse to renew a residential tenancy. Selling to a buyer who will live in the home is one of the allowed no-fault reasons, but notice requirements apply. If you plan to sell in two years, plan your lease terms around it. Our eviction guide explains for-cause rules.
• Security deposits, habitability and fees: see our guides to deposits, repairs and junk fees.

What about short-term rentals?

In Denver, generally no. The city licenses short-term rentals only in the owner's primary residence. If you've moved out, your Denver home isn't eligible for a short-term rental license.

When renting usually makes sense

• The home cash-flows, or comes close, at today's rents.
• You have a low fixed mortgage rate you'd lose by selling.
• You plan to hold for at least several years, or might move back.
• You have reserves for repairs and vacancy.
• You're ready to manage it, or to pay someone who will.

When selling usually makes sense

• The numbers are significantly negative every month.
• You'd lose the home-sale exclusion on a large gain by waiting too long.
• The home needs major work you don't want to fund.
• You need the equity for your next home.
• Being a landlord from a distance doesn't fit your life.

A middle path

Some owners rent for a year or two, then sell inside the 2-of-5 window, keeping the tax exclusion (minus depreciation recapture) while waiting for a better selling season. If that's your plan, choose lease terms that end when you'd want to list, and remember that Colorado's notice rules apply.

How to get help

Before you decide, get a rent opinion based on real comps and a clear cost breakdown. A good property manager can give you both, and should tell you plainly if renting doesn't pencil out. Pair that with advice from your tax advisor and lender.
