CDOM is the total number of days a property has been on the market. There are two types of DOM calculations, Cumulative Days on Market (CDOM) and Agent Days on Market (ADOM).
If a property is changed to Temporarily Off Market (TOM) or Pending it stops the DOM from accumulating days. Listings accrue Days on Market (DOM) while in either Active status or UCB status. 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. 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. How are the Cumulative Days on Market (CDOM) and Agent Days on Market (ADOM) calculated?
