How a Colorado Home Appraisal Works: Comps, Gaps, Deadlines

A Colorado home appraisal is a written opinion of market value from an appraiser licensed by the Colorado Division of Real Estate, built on closed sales of similar homes in the same area, adjusted for the differences between those homes and yours. On a financed purchase the buyer's lender orders it, the buyer pays for it, and the Colorado Contract to Buy and Sell Real Estate gives the buyer a dated deadline to object or walk if the number comes in under the contract price.

This guide covers how the appraiser reaches the number on a Front Range home, what moves it up or down (finished basements, garages, views, metro district taxes), the appraisal deadlines in the Colorado contract, the four ways to handle an appraisal gap, and how a seller learns the value before listing without paying for an appraisal at all.

Who appraises homes in Colorado and what it costs

Residential appraisers in Colorado hold one of three credentials from the Colorado Board of Real Estate Appraisers, part of the Division of Real Estate inside the Department of Regulatory Agencies (DORA): Licensed Appraiser, Certified Residential Appraiser, and Certified General Appraiser. A lender assigns the appraiser through an appraisal management company, so neither the buyer, the seller nor the agents pick the person.

A conventional appraisal on a Denver metro single-family home runs $500 to $800 in 2026. Expect the higher end for homes over 4,000 square feet, homes on acreage in Elbert or Park County, and rush orders. FHA and VA appraisals carry their own fee schedules, and a VA appraisal on the Front Range comes with the Tidewater process described in the Colorado VA appraisal guide.

The three ways an appraiser reaches a number

• Sales comparison approach. The appraiser pulls closed sales of similar homes from REcolorado and public records, then adjusts each sale for the differences. This is the approach on every Front Range house, townhome and condo appraisal.
• Cost approach. Land value plus the cost to rebuild the house today, minus depreciation. It shows up on new construction in Parker, Erie, Windsor and Castle Rock, and on unique homes with no close comps.
• Income approach. Value from the rent the property produces. It applies to duplexes, fourplexes and rentals, not to a home the buyer plans to live in. The Colorado duplex and multifamily buying guide explains how lenders read rent on 2-to-4-unit buildings.

Which comps a Front Range appraiser uses

The appraiser wants three or more closed sales from the same subdivision or the same square mile, closed within the last 90 days where the market provides them, and within 180 days as a fallback. In a Denver neighborhood like Platt Park or Berkeley, a mile is too far; the appraiser stays inside the same blocks because prices change street by street. In Elizabeth, Bennett or a mountain community west of Evergreen, the search radius stretches to several miles and a year of sales because there are fewer of them.

Pending and active listings appear in the report as support, but a closed sale is what sets the value. This is why a Colorado seller's own comps sheet matters: the agent hands the appraiser the closed sales that fit, and the appraiser is free to use or ignore them. The Denver seller pricing strategy shows how the Kenna Real Estate Group picks those comps before a home lists.

The adjustments that move a Colorado number

No two Front Range homes match, so the appraiser adds or subtracts for each difference between the comp and the subject home. These are the adjustments that show up on nearly every Colorado report:

• Finished basement. Below-grade square footage is reported separately from above-grade living area under the ANSI Z765 measuring standard, and it is worth less per foot than the main floor. A finished basement with a bedroom that has an egress window and a full bath adds real value; a bedroom without egress does not count as a bedroom. Read what Colorado buyers want in a finished basement before you finish one.
• Garage. A 2-car attached garage is the Denver metro baseline. A 3-car garage, an RV bay, or a detached shop on acreage draws a positive adjustment; a 1-car or no garage draws a negative one.
• Views. A direct mountain view from the main living level, an open-space or greenbelt backing, or a golf course lot is a paired-sales adjustment: the appraiser finds a comp with the same view and one without and measures the gap in price.
• Metro district and HOA. Two identical homes in Adams, Douglas or Weld County sell for different prices when one sits in a metropolitan district with a high mill levy and the other does not. The appraiser notes the district and its taxes and adjusts for the difference the market shows.
• Lot, age, condition and updates. A quarter-acre lot in Centennial against a tenth of an acre in Stapleton, a 1998 kitchen against a 2024 remodel, a 20-year-old roof against a hail-claim replacement from last summer.

The appraisal deadlines in the Colorado contract

The Colorado Real Estate Commission's Contract to Buy and Sell Real Estate (Residential) carries three dated appraisal terms in its deadline table: the Appraisal Deadline, the Appraisal Objection Deadline and the Appraisal Resolution Deadline. When the appraised value comes in below the purchase price, the buyer has until the Appraisal Objection Deadline to deliver written notice and terminate, or to propose a change, and the earnest money returns to the buyer on a timely termination. If the buyer and seller do not sign an agreement by the Appraisal Resolution Deadline, the objection ends the contract.

The buyer also holds a separate loan objection right tied to the New Loan Termination Deadline. Buyers read both before writing an offer; the guide to making an offer on a Colorado home walks through each date, and the escrow guide shows what happens between contract and closing.

When a Denver home appraises low: the four gap options

An appraisal gap is the difference between the contract price and the appraised value. A $650,000 contract with a $630,000 appraisal has a $20,000 gap, and the lender will lend on $630,000. The parties have four moves, and each one is decided before the Appraisal Resolution Deadline:

1. The buyer pays the gap in cash. The buyer brings the $20,000 on top of the down payment. Buyers who wrote an appraisal gap clause in the offer already agreed to this up to a stated amount.
2. The seller lowers the price to the appraised value. The seller nets $20,000 less and the deal closes on schedule.
3. The two sides split it. The seller drops to $640,000 and the buyer brings $10,000.
4. The buyer terminates. Written notice by the Appraisal Objection Deadline, earnest money back, and the seller relists with a number the market has already tested.

A fifth path runs alongside all four: a formal value review, which lenders call an ROV. Since 2024, lenders on conventional loans follow a standard ROV process, so the buyer's agent submits a handful of closed comps the appraiser did not use, with a written explanation of why they fit better. On a VA loan the Tidewater notice gives the agents two business days to send comps before the report is finished. A value review changes the number only when the new comps are stronger than the ones in the report; it does not change it because someone asked.

Assessor value, online estimates and the Smart Pricing Report

Three other numbers get confused with an appraisal. The county assessor's actual value is a property tax figure: Colorado assessors reappraise every home in odd-numbered years using sales from a data window that ends June 30 of the year before, so a Jefferson County notice mailed in May 2025 reflects sales through mid-2024, not this month's market. Online estimates come from an automated model that has never seen the inside of the house; they miss an unpermitted basement finish, a foundation crack, a mountain view and the metro district mill levy.

The Smart Pricing Report is the seller's tool. The Kenna Real Estate Group builds it from the same REcolorado closed sales an appraiser uses, applies the same adjustments for basement, garage, lot, view and condition, and adds the part an appraisal leaves out: the list price that brings the strongest offers in the seller's specific city and price band, the net proceeds after commission and closing costs, and the improvements that pay back before listing. Sellers request one on the Smart Pricing Report page, and the adding value guide lists which fixes move the appraised number and which do not.

How long an appraisal lasts and who can see it

A conventional appraisal report supports a loan for 120 days from the effective date, with a lender update possible after that. FHA appraisals attach to the property's FHA case number for 120 days, so a second FHA buyer on the same house inside that window inherits the first report. The buyer paid for the report and receives a copy from the lender. The seller has no automatic right to it; the buyer's agent shares it during gap negotiations because it is the only way to argue the comps.

On the financing side, the Kenna Real Estate Group works with Mike Oswald, VP of Mortgage Lending at Rate, NMLS 261003, Equal Housing Lender, who orders the appraisal early in the contract so a low number surfaces with time left before the deadlines. You are free to use any lender. Details and the pre-approval link are on the financing page.
