Pull up Redfin or Zillow and Denver shows homes selling in about 18 days. Pull up a different report and the number climbs past 50. Both figures are being presented as facts about the same market, in the same city, at roughly the same time.

They're both real. They're just measuring different things.

Days on market looks simple until you examine how it's calculated. Once you understand what each source is actually counting, reading Denver real estate data gets a lot clearer. That's what this post is for.

Why "Days on Market" Doesn't Mean One Thing

The confusion starts with the terminology. Depending on the source, "days on market" might mean two slightly different things.

DOM (Days on Market): The number of days from when a listing goes Active in the MLS to when it goes Pending (under contract). Some sources track this cumulatively across multiple listing periods; others reset the clock if a home is withdrawn and relisted.

DIM (Days in MLS): REcolorado's version of the metric, and the one DMAR uses in its monthly market reports. DIM counts only the days a listing is in Active status. Time spent in Coming Soon status, or in Withdrawn or Pending status, does not count. In Colorado, Coming Soon status is capped at 7 days, so the difference is small. But it's one reason DIM can slightly understate total marketing exposure.

Both are tracking the same transaction. They just draw the lines in different places.

How to Read Denver Real Estate Data: Why the Numbers Differ

Even when you know which metric a source is using, five variables can send the numbers in very different directions. Most sources make different choices on at least two of them.

1. What time period does this reflect?

This one matters more than most people expect. Denver's market moves significantly by season.

DMAR's February 2026 report showed the Denver metro median Days in MLS at 45 days across the first two months of the year. By March, that figure had dropped to 16 days. Same market, same metric. Just measured in winter versus spring.

A report citing 50-plus days on market for Denver metro isn't necessarily wrong. If it's based on winter data, it may accurately reflect how slowly things were moving before the spring surge. By April, the median had fallen to 14 days. The calendar matters enormously.

2. What geography does it cover?

Redfin's 18-day figure covers Denver city proper. DMAR's market report covers the full 11-county metro area, including Adams, Arapahoe, Jefferson, Douglas, and Boulder counties, suburbs that typically move more slowly than intown neighborhoods. A metro-wide median will trend higher than a city-only median even when both numbers come from the same underlying MLS.

3. What type of property?

This is the variable that gets overlooked most often, and it may matter as much as any of the others.

Condos and townhomes often take longer to sell than single-family detached homes across Denver, though the gap varies significantly by neighborhood. At the $500,000 to $750,000 range, detached homes averaged 31 days in MLS in April 2026. Attached homes averaged 48 days. (REcolorado, April 2026) Same price range, same time period, same city, and a 17-day gap just from property type.

The difference shows up clearly in specific neighborhoods. In Cap Hill, single-family homes rarely trade (only seven have sold so far in 2026), with a median of 14 days on market. The condo and attached market in the same zip code tells a different story: 69 transactions, a median of 51 days, and an average of 83 days pulled upward by a handful of units that sat for 300 to 400-plus days. Same zip code. Two very different markets.

4. What's the endpoint?

Some sources measure from listing date to the day a home goes pending (under contract). Others measure to the day it closes. Closing typically takes 30 to 45 days after a contract is signed. A source using closing date as its endpoint will always show a significantly higher number than one using pending date, even when everything else is identical.

5. Median or average?

This is where numbers diverge most sharply, and where it's easiest to be misled.

The $1 million-and-above segment in Denver illustrates the problem precisely. Year-to-date through 2026, the median Days in MLS for that price range is 21 days. The average is 62 days. (REcolorado, 2026 YTD) Same market. Same time period. A 41-day gap between the two statistics.

What explains it? A small number of overpriced or problematic homes that sit for 180, 200, or 300-plus days. Those outliers barely move the median, but they drag the average up dramatically. Median is almost always the more useful number for understanding what most buyers and sellers actually experience.

The neighborhood-level MLS data from Denver makes this concrete. In the RiNo area in 2026, three income-restricted condos sat for 350, 418, and 473 days, properties that couldn't be sold at market rate due to income qualification requirements built into the units. The other 13 units in the same dataset averaged around 69 days. The blended average for the neighborhood comes out to about 134 days. That number tells you almost nothing useful about buying or selling a market-rate condo in RiNo.

What This Means If You're Buying or Selling

For buyers

Days on market is one of the clearest signals of a seller's negotiating position. A home that has been sitting for 90 days in a market where most comparable homes sell in 20 is telling you something real: either the price is too high, there's a condition issue, or both.

That said, don't assume high DOM automatically means leverage. Context matters. A condo listed for 50 days in Cap Hill is right around the median for that market, not a sign of a desperate seller. The same listing in Sloans Lake, where the attached median is 14 days, would be well above it and worth asking about. Use neighborhood-level context when reading DOM on any specific property.

Hot homes in Denver are going pending in about 5 days right now, according to Redfin's May 2026 data. If you're targeting one of those, days on market is nearly irrelevant by the time you see it. The more useful question is whether the home is priced in line with recent sold comps, and whether you're prepared to move quickly.

For sellers

The Denver metro median Days in MLS is 16 days (REcolorado, May 2026). That's your benchmark. A well-priced home in good condition should land close to it.

Homes that sit significantly longer almost always have a pricing problem, not a marketing problem. If the market is moving in 16 days and your listing is approaching 60, that's the conversation to have before you consider anything else.

The pricing discussion before your home goes active is the most important one you'll have.

A Quick Framework for Reading Any Market Report

When you see a days-on-market figure for Denver, four questions cut through most of the noise:

  • What month is this from? A winter number and a spring number can differ by 50 percent or more in the same city.
  • Is this median or average? Average figures are more susceptible to distortion from outliers. Median is usually more useful.
  • Does it separate attached from detached? A blended figure is often less informative than either number on its own.
  • What geography does it cover? City-only data and 11-county metro data will produce different results even from the same underlying source.

No single number fully captures the Denver market. But with the right questions, you can get a lot closer to understanding what the data is actually saying.
