Relisting can reset MLS days on market (DOM) while cumulative days on market (CDOM) carries earlier exposure forward. The DOM vs. CDOM distinction separates the current listing’s counted time from counted exposure across linked listings. Local MLS rules determine which days count and when either counter restarts. A new listing number does not necessarily reset both.

What DOM and CDOM measure

These fields answer different questions:

• DOM: How much counted market time belongs to this listing?
• CDOM: How much counted time belongs to this property across the listings the MLS links together?
• ADOM: In systems using agent days on market, how much counted time belongs to this property with a particular listing agent?

FBS’s overview, last modified July 1, 2025, explains that ADOM replaces standard DOM where used. Check the field label before comparing records across MLS data systems.

A counter reset does not necessarily erase earlier records. Flexmls’s history documentation, updated March 29, 2023, describes a property history showing previous MLS numbers, prices and changes. The MLS chooses the fields used to match records, which may include address or parcel number. CDOM is a calculated measure of qualifying exposure, not a lifetime record of every marketing attempt.

Which statuses pause the counters?

Pausing accrual and qualifying for a reset are separate events. Arizona Regional Multiple Listing Service (ARMLS) illustrates the distinction. Under its calculation policy, modified October 5, 2023, Pending, Coming Soon and Temporarily Off Market (TOM) stop ADOM and CDOM from accumulating. Time in those statuses does not count toward its reset interval.

Cancelled and Expired also stop accrual, but they can count toward that interval. A Closed listing causes both counters to restart when the property is subsequently relisted, regardless of the gap. These are ARMLS rules; the status names do not carry universal reset rules.

When reviewing a withdrawal, establish the actual MLS status. A seller saying “we took it off the market” does not tell you whether the record was temporarily withdrawn, canceled or allowed to expire.

Reset periods differ by MLS

These dated MLS sources specify different intervals:

Permission to relist is a separate question. SmartMLS allows cancellation followed by same-day relisting with a new, fully executed listing agreement, while relisting as Coming Soon has additional restrictions. A new record can therefore be valid without qualifying for a cumulative days on market reset.

None of these intervals is a national waiting period. Before changing status, have your agent or broker confirm the required paperwork and exact qualifying date with the local MLS.

How 10 DOM can coexist with 50 CDOM

Consider a hypothetical MLS that counts only active days, restarts DOM for a new listing and carries prior exposure across a 14-day cancellation gap. Assume no ownership change or other reset exception.

A seller accumulates 40 counted days, cancels for 14 days, then relists and accumulates another 10 days. The result is:

• Current listing DOM: 10 days.
• CDOM: 50 days, combining 40 and 10.
• Elapsed time across the sequence: 64 days, including the break.

The 50-day count puts the latest listing in context, but it does not establish how long buyers have seen the current price or condition. If repairs or a price reduction accompanied the return, mark those changes on the timeline.

Why Zillow days on market can differ from MLS figures

A portal’s counter may use a different starting point or reset rule. Zillow’s help page updated December 12, 2023 says that for listings supplied through an Internet Data Exchange (IDX) feed, Time on Zillow uses the MLS-provided On Market Timestamp. Zillow cannot manually change that source-controlled value.

For non-IDX feeds, the same guidance describes separate reset conditions. For example, relisting with the same agent and a different MLS number does not reset its counter unless the property was off market for at least 31 consecutive days. That condition applies to the specified Zillow feed treatment; it is not an MLS reset standard.

Coming Soon can also explain a mismatch. SmartMLS’s November 8, 2023 syndication guidance explains that downstream sites can count public Coming Soon exposure while SmartMLS DOM begins when the listing becomes Active. Different starting points can produce different figures without either record being erroneous.

Read the full MLS listing history before judging performance

Request the property history across listing numbers, not just the current listing’s change log. SmartMLS distinguishes those reports in its February 8, 2024 instructions.

Use that history to establish when buyers could encounter the home, the actual status during each interruption, and the price and condition offered during each active period. Investigate unexplained gaps before treating a low current DOM as evidence of a fresh offering.

Brokerage analysts should compare the same counter, set of statuses and reporting period when evaluating market speed and inventory measures. Keep time attributed to a single listing distinct from the property’s counted exposure across linked listings.

For sellers, understanding listing performance means connecting that history to a decision: whether the current price, presentation and showing access have had a fair test. A smaller counter alone does not show that those conditions improved.
