Renovate and List or Sell As-Is? A Denver Numbers Framework

Renovate before listing a Denver metro home when the added sale price beats the renovation cost plus the carrying cost of the extra months by 20 percent or more. Sell as-is when it does not, when the money is not available up front, or when the extra months collide with a move date. Everything below turns that rule into a table you fill in with your own numbers.

The costs below are Front Range ranges, not national averages. Bring your own quotes and the framework still holds.

The formula: added value minus cost minus carrying cost

Every project gets four numbers. Cost is the contractor quote plus 10 percent for surprises. Added value is the difference between what the home sells for with the work done and what it sells for without it, taken from sold comps on the same street type, not from a national remodeling survey. Added months is how long the project pushes the listing date. Carrying cost is added months multiplied by what the home costs to hold each month.

• Net gain = added value minus cost minus carrying cost.
• Do the project when net gain is positive and at least 20 percent of the cost. The margin covers the quote coming in high and the comps coming in low.
• Skip the project when net gain is negative. Price the home for the condition instead.
• Required repairs (roof, active leaks, dead furnace, failed sewer line) get a different test: the cost of the repair versus the credit or price cut a buyer demands for it. In the Denver metro that credit runs 1.5 to 2 times the repair cost, because the buyer prices in hassle and risk.

What it costs to carry a Denver metro home for one month

Carrying cost is the number sellers forget. On a home with a mortgage in Arapahoe, Jefferson or Adams County, one month of holding runs $3,000 to $5,000 once principal, interest, property tax, insurance, Xcel Energy, Denver Water or the local district, lawn care and HOA dues are added up. A paid-off home still carries $900 to $1,800 a month in tax, insurance and utilities. Multiply that by the months the project adds. A three-month kitchen remodel on a mortgaged home costs $9,000 to $15,000 before the first cabinet arrives.

Two Colorado items push the number up. A vacant home needs a vacancy endorsement or a separate policy after 30 to 60 days empty, and winter holding means running the furnace so the pipes do not freeze.

Worked example: a 1978 Aurora ranch

The house: a 1,600 square foot brick ranch near Aurora's Utah Park, unfinished basement, original kitchen, 22-year-old roof with 2023 hail bruising, carpet throughout. As-is value from sold comps: $440,000. Carrying cost: $4,000 a month. Every number in the table is an estimate for this example, built from Front Range contractor ranges and recent sold comps, so a home in Lakewood or Arvada gets its own version.

The answer for this house: paint, floors and the roof, then list at $485,000 to $495,000. Total spend $34,500, added value and avoided credits $56,000, five weeks added. The kitchen and basement lose money for this seller, because the buyer who wants a finished basement in Aurora pays for one that already exists, not for the seller's version at full retail. The preparing and adding value before selling page lists the projects that clear the bar across the metro.

Which projects clear the 20 percent bar on the Front Range

• Interior paint in a warm white. $4,000 to $8,000 on a 2,000 square foot home. Returns 150 to 200 percent because Colorado's 300 days of sun show every scuff and every 1990s beige.
• Flooring replacement where carpet is worn. Luxury vinyl plank runs $6 to $12 per square foot installed. Returns more than cost on main levels, less in bedrooms.
• Roof with hail damage. A roof past 20 years or with hail bruising fails the buyer's inspection and, in 2026, fails many insurers. Class 4 impact-resistant shingles cost $12,000 to $25,000 on a 2,000 square foot home and earn an insurance discount the buyer sees in the quote. The Colorado roof replacement cost guide has the material comparison.
• Sewer line spot repair. Clay laterals in pre-1975 Denver, Lakewood and Arvada homes crack from tree roots and bentonite soil movement. A spot repair costs $3,000 to $7,000 and prevents a buyer walking or demanding a $15,000 to $25,000 credit for a full replacement.
• Radon mitigation. Most Front Range counties sit in EPA Zone 1. A mitigation system costs $1,200 to $2,500 and removes the single most common inspection objection in the metro. Since 2023 Colorado law requires sellers to hand buyers a radon warning statement and any known test results.

Which projects lose money before a Colorado sale

• Full kitchen and bath remodels. $50,000 to $90,000 for a mid-range Front Range kitchen; buyers pay 60 to 75 percent of that back. The exception is a home above $1.2 million in Cherry Hills Village, Greenwood Village or Boulder, where an original kitchen removes the home from the buyer pool.
• Basement finishes. $40 to $75 per square foot plus $4,000 to $8,000 for an egress window. Appraisers give finished below-grade space a fraction of above-grade value.
• Additions and pop-tops. $250 to $400 per square foot in Denver and six to twelve months with permits from Denver Community Planning and Development.

What as-is means in the Colorado contract

Every Colorado resale uses the Colorado Real Estate Commission's Contract to Buy and Sell Real Estate. There is no as-is checkbox. As-is is a listing description and a negotiating stance: the seller states that no repairs or credits come with the price. The buyer still gets an inspection objection deadline and an inspection termination deadline, and the buyer still walks away with the earnest money if the inspection turns up something they did not sign up for. What an as-is stance does is set the expectation up front, so the offers that arrive already price the condition in.

The Seller's Property Disclosure still applies. Colorado law requires a seller to disclose known adverse material facts, as-is or not. A cracked sewer line the seller knows about, a basement that took water in the 2013 or 2023 storms, a Federal Pacific panel a previous inspector flagged: all of it goes on the form. As-is protects a seller from paying for repairs; it never protects a seller from a nondisclosure claim.

Who buys as-is homes in the Denver metro

Three buyer groups. Owner-occupants using conventional or renovation financing, who want a discount and plan to do the work themselves. Local investors and flippers, who buy at 70 to 80 percent of after-repair value minus repair costs. And Professional cash home buying companies, which close in 7 to 21 days with no inspection contingency and price the home the same way a flipper does. The Denver cash home buyers and fast sale choices page shows how those offers compare with a listed as-is sale.

The listed as-is sale beats the cash offer for most Front Range sellers because owner-occupants pay more than any investor. The cash offer wins when the seller needs to close in under three weeks or the home is not showable.

Inherited homes: the decision changes

An inherited Denver home gets a stepped-up federal tax basis at the date of death, so the heirs owe capital gains tax only on appreciation after that date. That removes most of the tax reason to hold and renovate. Colorado has no state inheritance tax and no state estate tax. Rules on who inherits and how a probate sale gets approved fall under inheritance law that differs by state; in Colorado the personal representative sells through the probate court process, and the personal representative signs the Seller's Property Disclosure with what they know.

Out-of-state heirs carry a vacant home at $1,500 to $4,000 a month with nobody local to manage a contractor, so the right call for most estates is a clean-out, paint if the estate has the cash, and an as-is listing priced from comps. The selling an estate home in Colorado guide walks the probate steps.

Pricing an as-is home in Denver

An as-is home is priced from three numbers: the sold price of updated comps, the cost of the work the home needs, and the hassle premium buyers charge for doing it. Take the updated comp, subtract 1.5 times the repair cost, and that is the top of the as-is range. The Smart Pricing Report the Kenna Real Estate Group builds for every seller shows the updated comps and the as-is comps side by side, so the seller sees both prices before choosing a path. The Denver seller pricing strategy post covers how to set the number when inventory is high.

The timeline difference

• Sell as-is, listed: 1 to 2 weeks to prepare, 20 to 45 days on market in the current metro, 30 to 40 days to close. About 10 to 13 weeks door to door.
• Sell as-is, cash buyer: 2 to 4 weeks door to door, at a 10 to 25 percent lower price.
• Light refresh then list: adds 2 to 4 weeks. Paint, floors, fixtures, cleanup.
• Kitchen or bath then list: adds 8 to 14 weeks, longer when Denver permits are involved.
• Basement or addition then list: adds 4 to 9 months.

Doing part of the work

Most Front Range sellers land in the middle: fix what fails inspection or financing, refresh what is cheap and visible, and leave the big remodels for the buyer. The room-by-room Front Range renovation cost guide prices each project separately.

When as-is is the better net number

• The work costs more than 15 percent of the as-is value and the seller would finance it.
• The move date is fixed by a job, a closing on the next home or a lease.
• The seller is out of state and nobody local manages the contractor.
• The home has a systemic issue (foundation movement on bentonite clay, a full sewer replacement, a Federal Pacific panel plus galvanized plumbing) that a flipper prices better than an owner-occupant.
• The neighborhood ceiling is close. When updated comps in the same Lakewood or Westminster subdivision top out $40,000 above the as-is value, no $60,000 project pays.

The checklist version of this decision is in the Colorado Home Seller's Guide.
