Should I Rent My Colorado House If It Will Not Sell? The Math

Rent the house when three comparable homes within a mile leased in the last 60 days for at least 125 percent of your mortgage payment with taxes and insurance. That extra 25 percent pays for vacancy, management and repairs. When the leased comps come in under that line, renting is a monthly loss, and a Denver metro home that did not sell in 60 days has a price problem that a tenant does not fix.

This post is the yes-or-no math. The 10 questions to answer before renting a Colorado home is the operating checklist once the math says yes. The Kenna Real Estate Group at Keller Williams DTC runs both with owners across the Front Range.

Why did the house not sell?

Three reasons cover it. The price sits above the last three sold comps. The condition shows an inspection item Colorado buyers walk from: a failed sewer scope, a hail-worn roof, a 25-year-old furnace, or radon above 4 pCi/L with no mitigation. Or showings were blocked by a tenant, a pet or a schedule. Each has a cost to fix, and that cost is the first number to compare against a year of landlording.

• Price. A 3 percent cut on a $550,000 Aurora home is $16,500 once. Renting the same home at a $500 monthly loss is $6,000 a year, every year, plus the selling costs you still pay later.
• Condition. A sewer line replacement on the Front Range runs $8,000 to $15,000; radon mitigation $1,200 to $2,500; a furnace $4,000 to $7,000. A tenant does not remove the defect, and Colorado's warranty of habitability makes the furnace your problem inside days of a written complaint.
• Access. Move out, stage, and re-list. The pricing your Colorado home page shows how a Smart Pricing Report sets the number from sold comps instead of hope.

Does the rent cover the payment plus 25 percent?

Three Denver metro owners, same $550,000 house, same $3,000 leased-comp rent. Only the mortgage differs.

Owner A nets about $375 a month after the reserves below and keeps a 2021 rate. Owner B loses $600 a month before a single repair, which is $7,200 a year to hold a home that a 3 percent price cut sells. Owner C is paying to hold a home that has no equity to protect; the am I underwater on my mortgage page starts that conversation.

What vacancy should I assume in the Denver metro?

One month per year, or 8 percent of annual rent. On $3,000 rent that is $250 a month set aside. Turnover on the Front Range costs another $1,500 to $3,000 each time: cleaning, paint touch-up, carpet cleaning, re-keying, and a leasing fee of half to one month's rent when a manager places the tenant. A lease that ends in December instead of June adds two to four weeks to the vacancy, so write leases that end between May and August. The Apartment Association of Metro Denver publishes vacancy by county each quarter; our state of the Denver rental market post reads it for owners.

What does management cost, and should I self-manage?

Denver metro property managers charge 8 to 10 percent of collected rent plus the leasing fee. On $3,000 rent, that is $240 to $300 a month. Self-manage when the home is within a 30-minute drive, you answer a phone at 2 am, and you have a furnace contractor, a plumber and a roofer who call you back the same day. Owners who moved to Fort Collins or out of state and kept a Littleton house hire a manager; the savings from self-managing disappear the first time a habitability repair waits a week because nobody was in town.

What do repairs cost per year on a Front Range rental?

Set aside 1 percent of the home's value each year, $458 a month on $550,000, and expect it to be spent in lumps.

• Furnace. $4,000 to $7,000 to replace; 15 to 20 years of life at Front Range altitude.
• Water heater. $1,500 to $2,500 installed; 10 to 12 years.
• Roof. Hail season runs May to September. A claim costs you the deductible, and Colorado carriers write percentage deductibles of 1 to 2 percent of the dwelling coverage, $5,000 to $10,000 on this house.
• Sewer line. $8,000 to $15,000 when clay or Orangeburg pipe under a pre-1980 Denver, Arvada or Englewood home fails.
• Sprinkler and hose bibs. $300 to $800 a year in freeze repairs when the blowout is late.

Owner A's $375 a month covers this reserve. Owner B's loss grows to $1,058 a month once vacancy, management and repairs are counted honestly.

How does the capital gains exclusion clock run once I rent?

The federal Section 121 exclusion, $250,000 of gain for a single filer and $500,000 for a married couple filing jointly, requires the home to have been your primary residence for two of the five years before the sale. Move out today and the clock gives you three years to close a sale with the exclusion intact. Sell in year four and the entire gain is taxable at federal capital gains rates plus Colorado's flat income tax, and the depreciation you took as a landlord is recaptured at sale in every case. An owner with $200,000 of gain on a Centennial home is deciding between a tax-free sale now and a taxable one later, which is a bigger number than a year of rent.

What if I am underwater?

Renting a home that is worth less than the loan defers the problem and adds a tenant to it. The owner still owes the shortfall at sale, still pays the monthly loss, and now carries Colorado landlord duties. Owners who bought in 2022 or 2023 with an FHA or VA loan and 3 to 5 percent down are the ones we see in this spot. A short sale, a loan modification, or holding as an owner-occupant until the balance drops are the three real paths. The short sale, foreclosure or stay comparison and the Colorado short sales guide lay them out without a sales pitch.

Can I buy the next home while renting this one?

Yes, once the lender counts the rent. Owner-occupied conventional, FHA and VA loans require 12 months of occupancy before the home becomes a rental. After that, a signed lease lets the lender count 75 percent of the rent against the old payment, so Owner A qualifies for the next purchase with most of the old payment offset and Owner B carries the $600 gap into the debt-to-income ratio. Mike Oswald, VP of Mortgage Lending at Rate, NMLS 261003, Equal Housing Lender, runs that qualification for Kenna clients before they list or lease. You are free to use any lender. The Colorado home financing guide lists the programs, and the Colorado mortgage pre-approval guide covers the paperwork.

How much appreciation does a losing rental need to break even?

Owner B loses $1,058 a month, $12,700 a year with reserves. Selling costs on the Front Range run 6 to 8 percent of the price, about $38,000 on $550,000, and they are paid whether the sale is this year or in three. To break even on a three-year hold, the house has to gain $38,000 in carrying losses on top of the selling costs already baked in, which is 7 percent over three years just to get back to zero. That is a bet on the market, not an investment, and the money lost each month is gone even when the bet pays. Owner A, by contrast, needs no appreciation at all; the tenant pays the loan down $700 a month and the rest is cash flow.

Which Colorado rules apply the day a tenant moves in?

• Security deposit. Capped at one month's rent (the cap dropped from two months on January 1, 2026), returned within 30 days of move-out (up to 60 when the lease says so) with an itemized statement. Bad-faith withholding costs three times the deposit plus attorney fees.
• Warranty of habitability. Heat, water, electrical, a roof that keeps weather out, and no mold or pests. Written notice from the tenant starts a repair clock measured in hours for conditions that threaten health and in days for the rest.
• Denver rental license. Required for every long-term rental inside the City and County of Denver, after an inspection by a Denver-certified inspector, before a tenant moves in.
• HOA and metro district. Read the covenants for rental caps and minimum lease terms; the metro district mill levy is inside the tax bill the rent has to cover. The Denver HOA rules and fees guide explains what to pull.
• Disclosures. Colorado requires a radon disclosure to every tenant; federal law requires lead-based paint disclosure on pre-1978 homes.
• Late fees and non-payment. Seven-day grace period, late fee capped at $50 or 5 percent, and a 10-day demand for compliance before an eviction is filed in county court.

Can I put the house back on the market with a tenant in it?

Yes. The lease survives the sale, the buyer takes the home subject to it and receives the deposit at closing, and investors buy tenant-occupied homes across Adams and Arapahoe counties every month. A tenant-occupied home shows less and sells for less than a vacant, staged one, so the better plan is a lease that ends in April or May and a listing the week after move-out. Colorado's 2024 for-cause eviction law lets an owner decline to renew in order to sell, with 90 days' written notice. The how to sell a house in Colorado guide covers the timeline from there, and the rent it or sell it decision guide covers the case where the home never went on the market at all.

The one-sentence answer

Rent the house when the leased comps beat your payment by 25 percent and you will hold it three years or less without losing the capital gains exclusion; otherwise cut the price to the sold comps and sell, because a tenant does not fix a listing that was priced wrong. Sellers who want a fast exit have cash options too; the Denver cash home buyers guide shows what those offers net.
