Ask David: How is Days on Market (DOM) Data Shown in Listings?

Days on Market (DOM), Days on Market at Most Recent List Price (PDOM), and Cumulative Days on Market (CDOM) each provide different perspectives on a property’s market exposure. How they are calculated and displayed on other cooperating websites may differ, but this is what you’ll see while accessing and managing listings in NorthstarMLS systems:

DOM tracks the number of days a listing remains active under its current MLS number and resets if relisted under a new MLS number.

PDOM specifically measures the time a property has been listed at its most recent price, resetting overnight after a price change.

CDOM reflects the total market time for a property with the current owner over the past 12 months, even if relisted under different MLS numbers. It provides a broader view of the property’s time on the market. Understanding these distinctions helps sellers and buyers assess market trends and pricing strategies more accurately.

The days on market calculations are conducted automatically by the database and update after overnight processing.

Quick Tips

• DOM will reset if the property is listed under a new MLS listing number.
• PDOM will reset if the price is changed on the listing.
• CDOM only resets if the listing has been off of the market for 356+ consecutive days OR the property sells (changes owners). CDOM will not reset even it the property is listed with a different agent, different brokerage, or different association.
