Did you hear the news?

If you list properties in Unlock MLS, there is a significant change to Cumulative Days on Market, commonly known as CDOM, that could impact how you advise sellers, time a relaunch, and approach your listing strategy.

And this is one update we think agents are going to be happy about.

Effective September 8, 2026, Unlock MLS reduced the CDOM reset period from 90 days to just 30 days.

Yes, you read that correctly.

90 days is now 30 days.

For years, a property generally needed to remain off market for 90 days before its Cumulative Days on Market could reset. Under the new Unlock MLS policy, a property that remains off market in Withdrawn or Expired status for at least 30 consecutive days can now be entered as a new listing with its CDOM reset to zero.

For REALTORS® working with sellers who need to pause, reposition, improve, or relaunch a property, that is a substantial change.

At Capital City Coordination, our coordinators spend their days working behind the scenes of real estate transactions and listings. Because our team is made up of experienced, licensed REALTORS®, we understand that MLS changes like this aren’t just technical updates. They can directly affect listing strategy, seller conversations, timelines, marketing, and the administrative work required to properly bring a property back to market.

So, let’s recap what changed, what agents need to know, and why we think this is great news.

First, What Exactly Changed?

Previously, Unlock MLS required a property to remain off market for 90 days before its CDOM could reset.

As of September 8, that period has been reduced to 30 days.

According to the Unlock MLS FAQ, a property must remain in Withdrawn or Expired status for at least 30 consecutive days before CDOM resets to zero when a new listing is entered.

There is also an important detail for agents who use Flex listings.

A Flex listing can be used during the 30-day reset period and can count toward the 30 days required for the CDOM reset.

When using Flex, Unlock MLS advises that the Flex Deactivate Date, meaning the date the listing leaves Flex, must be greater than 30 days from the previous listing’s off-market date for CDOM to reset.

And there is another piece of good news for listings that were already off market when the rule changed.

Any Expired or Withdrawn listing that has been off market since August 9, 2026, may now be eligible to be relisted with zero CDOM under the new policy.

That means some agents may have listings sitting off market right now that are already eligible for a fresh CDOM start.

It may be worth taking a look at your roster.

Wait, What’s the Difference Between ADOM and CDOM?

If you have ever looked at an MLS listing and wondered why there are two different Days on Market numbers, this is where ADOM and CDOM come into play.

ADOM, or Agent Days on Market, tracks the days associated with a specific listing ID.

CDOM, or Cumulative Days on Market, follows the property’s market time across multiple listing IDs until the MLS requirements for a reset have been satisfied.

Think of it this way.

A new listing number can give you a new ADOM count, but that does not necessarily mean the property’s CDOM starts over.

Under the previous Unlock MLS policy, if a property was withdrawn or expired and then relisted before completing the required 90-day period, its cumulative market time generally followed it.

Now, that reset can occur after just 30 consecutive days off market, assuming all Unlock MLS requirements are satisfied.

That is a dramatically shorter window.

Why Is the 30-Day CDOM Reset Such a Big Deal?

Anyone who has worked listings knows that Days on Market can influence the way a property is perceived.

Buyers notice it.

Buyer’s agents notice it.

Sellers definitely notice it.

When a listing has accumulated significant market time, buyers may start asking questions.

Why hasn’t it sold?

Is it overpriced?

Is there something wrong with the property?

Has another buyer backed out?

How motivated is the seller?

Sometimes those questions are completely reasonable.

Other times, the number simply doesn’t tell the entire story.

A seller may have temporarily withdrawn the property for personal reasons.

The home may have needed repairs or improvements.

The seller may have decided to pause showings.

The listing strategy may have changed.

A property could have been taken off market for staging, renovations, landscaping, photography, or other updates.

The seller may have changed agents.

Or market conditions may simply have shifted.

Under a 90-day reset period, a seller who legitimately needed to pause their listing had to wait roughly three months before receiving a fresh CDOM count.

That’s a long time in real estate.

With the new 30-day policy, there is significantly more flexibility to pause, regroup, and return to market.

A Lot Can Change in 30 Days

Real estate markets don’t operate on a 90-day schedule.

Interest rates can move.

Inventory can change.

Buyer activity can pick up.

Competing listings can sell.

A new school year can begin.

A major employer can announce changes.

Seasonal demand can shift.

A seller can complete meaningful property improvements.

Even pricing strategy can look very different a month later.

That is one reason the new policy makes sense from a practical listing perspective.

Unlock MLS explained that its Compliance Committee and staff determined the previous 90-day period was longer than necessary and did not accurately reflect current market conditions. The 30-day period is intended to better balance transparency for buyers with fairness for sellers.

From a coordinator’s perspective, we see another benefit: it gives agents more options.

Instead of feeling like a property is tied to its previous market history for an entire quarter, agents can have a more realistic conversation with sellers about whether a temporary pause and strategic relaunch makes sense.

Of course, this does not mean every listing should be withdrawn for 30 days just to reset CDOM.

MLS rules should never replace thoughtful pricing, positioning, marketing, or seller guidance.

But when there is a legitimate reason for a listing to come off market, the seller now has a much more reasonable path to a fresh CDOM count.

What Happens If You Relist Before the 30 Days Are Complete?

This is an important one.

The new rule does not mean CDOM automatically resets whenever you create a new listing.

If a property is relisted before the full 30-day reset period has been completed, its CDOM continues to carry forward.

In other words:

29 days is not 30 days.

Agents should be careful when calculating dates, particularly when planning photography, marketing, listing paperwork, MLS entry, and a targeted go-live date.

This is exactly the kind of detail that can become important when you’re coordinating a relaunch.

The last thing you want is to build an entire marketing strategy around a fresh listing only to discover that the property was activated too early to qualify for the CDOM reset.

What About Flex Listings?

Unlock MLS has also confirmed that Flex listings can be used during the 30-day CDOM reset period.

That creates another option for agents who are preparing a property for its return to the active market.

However, the dates still matter.

According to the Unlock MLS guidance, when using Flex, the Flex Deactivate Date must be greater than 30 days from the previous listing’s off-market date for the CDOM reset.

This is another reason we recommend agents think about the listing timeline as a whole rather than simply focusing on the day they want the property to go Active.

There may be listing documents to prepare.

Signatures to obtain.

MLS fields to complete.

Photos to schedule.

Marketing copy to write.

Showing instructions to confirm.

Title information to organize.

Brokerage compliance requirements to complete.

And now, depending on the circumstances, a CDOM reset date to consider.

The actual listing launch may be one day on the calendar, but there is a lot happening behind the scenes before you get there.

From a Coordinator’s Perspective, This Is Great News

At Capital City Coordination, we look at MLS updates through a slightly different lens.

We’re asking:

What does this change for the agent’s workflow?

Because a policy change is only helpful if you know about it and know how it affects the work you’re doing.

For agents, this particular change creates an opportunity to be more strategic when discussing listing timelines with sellers.

If you have a seller considering withdrawing a property to make updates, for example, you now know that the potential reset window is substantially shorter than it was before.

If you have an expired listing you are preparing to relaunch, you need to know exactly how long it has been off market.

If you’re taking over a listing from another agent, understanding the property’s MLS history and CDOM may be an important part of preparing your new listing.

And if a listing has been Expired or Withdrawn since August 9, it may already qualify under the new rule.

These are details worth catching.

Have a Listing Coming Back to Market? Start With the Dates

Before promising a seller that their CDOM will reset, verify the property’s MLS history and applicable dates.

A few questions to consider:

When did the previous listing officially go off market?

Was it Withdrawn or Expired?

Has the property remained off market for at least 30 consecutive days?

Will a Flex listing be used?

If so, does the Flex timeline comply with the reset requirements?

What date are you targeting for the new listing to become Active?

Does the brokerage have any additional procedures or compliance requirements?

Are new listing documents required?

Has anything changed regarding price, exclusions, inclusions, showing instructions, seller disclosures, or other property information?

A CDOM reset is only one piece of bringing a listing back to market.

The goal is not simply to get a new number.

The goal is to relaunch the property correctly and strategically.

This Is Also a Good Time to Review Your Listing Process

MLS changes are a good reminder of how much goes into listing a property.

Agents are often focused on the seller, pricing strategy, preparing the home, generating business, hosting open houses, negotiating offers, and keeping their pipeline moving.

Meanwhile, there is an entire administrative side of the listing that still needs attention.

That’s where Capital City Coordination comes in.

Our Listing Coordination service is designed to help REALTORS® manage the behind-the-scenes details required to get a listing organized, entered, and launched.

And because our coordinators are licensed, experienced REALTORS®, we understand the real estate process behind the checklist.

We aren’t simply checking boxes.

We understand why the dates matter.

We understand MLS terminology.

We understand listing paperwork.

We understand brokerage compliance.

We understand how the different parties fit into the process.

Most importantly, we understand how quickly an agent’s day can disappear when you’re trying to do all of this yourself.

Let Us Help With Your Next Listing

If you’re reading about this CDOM update while also thinking, I have a listing I need to get ready, this is your reminder that you don’t have to handle every administrative detail yourself.

Our Full Listing Coordination service is designed to support agents from the behind-the-scenes preparation of the listing through launch.

Depending on the listing and brokerage requirements, our team can assist with tasks such as organizing listing documentation, MLS entry, compliance coordination, title opening, listing details, marketing copy, and other administrative pieces that help move a listing toward Active status.

Need something more limited?

We also offer Listing Compliance Only and Listing Compliance + Corrections options for agents who may not need full Listing Coordination but still want an experienced set of eyes helping with the compliance side of the file.

Our goal is simple:

You stay focused on the seller and the strategy. We help manage the details behind the scenes.

That division of responsibility becomes especially valuable as MLS rules, forms, brokerage requirements, and real estate workflows continue to change.

Information Is Part of Good Coordination

We believe great transaction and listing coordination involves more than moving documents from one place to another.

Our coordinators work inside real estate every day.

We see the forms.

We see the deadlines.

We see the MLS changes.

We see the compliance requirements.

We see the questions agents encounter repeatedly.

That’s why we think it’s important to share updates like this.

An agent shouldn’t discover a major MLS policy change by accident while entering a listing.

And you definitely don’t want to be working from an old 90-day rule when the requirement has already changed to 30 days.

So, if you missed the announcement, consider yourself caught up.

As of September 8, 2026:

Unlock MLS CDOM now resets after 30 consecutive days off market rather than 90 days.

Expired and Withdrawn listings can qualify for the reset.

Flex can be used during the reset period when the applicable requirements are followed.

Relisting before the required 30 days means the previous CDOM continues to carry forward.

And properties that have been Expired or Withdrawn since August 9 may already be eligible for a zero-day CDOM when relisted, subject to the Unlock MLS requirements.

That’s a big change.

And for many agents and sellers, we think it’s a very welcome one.

The Market Changes. Your Support Should Keep Up.

Real estate doesn’t stand still.

Forms change.

MLS rules change.

Brokerage policies change.

Markets change.
