How are the Cumulative Days on Market (CDOM) and Agent Days on Market (ADOM) calculated?

On the Arizona Regional Multiple Listing Service (ARMLS), Arizona's MLS, Days on Market (DOM) refers to the number of days that a property takes to sell, from the time that it is listed to the time an accepted contract is signed. Once a property is listed on the MLS and Active, DOM will begin at zero if it has not been listed (and Cancelled or Expired) in the last 90 days.

Listings accrue Days on Market (DOM) while in either Active status or UCB status. If a property is changed to Temporarily Off Market (TOM) or Pending it stops the DOM from accumulating days.

There are two types of DOM calculations, Cumulative Days on Market (CDOM) and Agent Days on Market (ADOM). CDOM is the total number of days a property has been on the market. ADOM is the amount of days the current Realtor has had the property listed on the MLS.

Once a property is listed for the first time in 90 days, both the CDOM and the ADOM begin at zero. If the listing is Cancelled or Expired and the seller relists the property with a different Realtor within 90 days, the CDOM from the previous listing period will carry over to the new listing. The ADOM will begin at zero since it was listed with a new Realtor. If the seller relists with the same Realtor within 90 days, the ADOM will also carry over from the old listing. So in other words, in order to have the CDOM start at zero again after a seller cancels or lets a listing expire, the seller must wait 90 days to relist the property.
